My floppy-controller is interrupt-driven and, as I realized this week, has an interrupt pending after power-on. Normally the interrupt is cleared after a floppy-operation, which had been done first after switching my computer on. But now I have switched to a hard-disk which doesn't use the floppy-controller any more, so the interrupt remains active. This led to the following problem: At power-on all interrupts are disabled with DI The system boots and logs drive A, the hard-disk. I'm running ZCPR3.3, so arunz is invoked to fiddle around with aliases, and I use much of them. The system crashes immediately. It took me a long time to think of arunz as the problem, but as I debugged arunz I found to my surprise DI and EI instructions, which led of course to problems, as no interrupt routines exist as default. Now my question is: Do I have to check all my programs to find out which of them play around with the interrupt system or is arunz a rare exception (as I hope) that uses DI,EI instructions? Until now I have thought that only the bios or some very specialized user programs should use the interrupt system. I hope someone has a opinion on this and may enlight me on this subject. Thank you very much Martin Frerichs PS: I remember that someone looked for a gif-viewer for cpm. If there is still interest I can mail my version in turbo-pascal. It needs routines to draw lines and points on the screen. Alternatively I have adopted an include that prints to a file which may be send to a NEC printer. ----------------------------------------------------------------------- My email-address: mfreric@dgogwdg1.bitnet My smail-address: Martin Frerichs An der Stupe 3 W-3405 Rosdorf Germany ------------------------------ Date: 4 Mar 92 07:05:03 GMT From: baron!baron!pnet07!donm@nosc.mil (Don Maslin) Subject: Re: Z80 S-100 and SBC system help needed Message-ID: <1992Mar4.070503.28073@baron.uucp> Sorry about the bandwidth used, but none of his addresses would work for me!

This machine is apparently different enough from the other Sanyos (models 10xx and 11xx) that the standard Sanyo installation does not work. A messed up screen indicates that the terminal emulation is quite different, and with the screen garbled it is hard to check out the serial port operation. If no one has a MEX overlay for this machine, an IMP or MDM740 overlay would be almost as good. Lacking that, some straight technical information about the UART and its port addresses and the codes used by the screen would probably get us going.

Four respondents suggested reading data from the printer port, but unfortunately the degree of access I have to the CPT does not extend that far - I can use the CPT to print to paper, but not to tickle its backside or innards. Likewise for running Kermit or PIP. Two respondents suggested using any commercial service that uses the Shaftstall conversion package - apparently a very good product, but naturally not cheap.

In return for contributions to help fund user group activities, we would like to find new homes for these items where they would be put to good use. You may communicate your offers in any of the following ways: (1) by leaving a message on the Zi/Tel BBS in the Boston area at 617-965-7046 (or 617-965-7785 to limit access only to the USR Courier HST modem on line 2) (2) by leaving a message on Jay Sage's Z-Node at 617-965-7259 (logon password is DDT) (3) leaving GEnie mail for JAY.SAGE (4) sending email to Jay Sage on Internet at the following address: sage@ll.mit.edu (5) sending postal mail to Jay Sage at 1435 Centre Street Newton, MA 02159-2469 (6) telephoning Jay Sage at 617-965-3552 weekday evenings or Sunday or during weekday days at 617-981-4704 The last method will probably be the least reliable and may take several tries.

Now for the inventory of items! +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ First, there are boxes and boxes of HARD-SECTORED diskettes. So far there have been no firm or accepted offers for these. 18 boxes of 8" 32-sector hard-sector diskettes 17 boxes of 5.25" 10-sector hard-sector diskettes 7 boxes of 5.25" 16-sector hard-sector diskettes +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Then there is some miscellaneous hardware: 1 Televideo 802H (CP/M with hard disk) 1 Soroc 135 terminal 1 Kaypro that needs work (probably fixable, certainly good for parts) 1 mint condition Kaypro 2 with ComRiter diasy-wheel printer, original manuals 1 Osborne 1, condition unknown These items probably make sense only for people in the greater Boston area or for people who can take delivery at the Trenton Computer Festival in April. +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Next, there is the software. We will start with the CP/M items. There are lots of copies of MicroPro packages in sealed, shrink-wrapped boxes. Most were originally for Apple CP/M. I opened one of the boxes and was able to read the diskettes using Uniform and my special disk controller. Thus, there will be no trouble converting the contents over to just about any other CP/M format. People who have purchased these have been very satisfied. 7 WordStar 3.31 7 MailMerge 3.30 7 SpellStar 3.30 1 WordStar - MailMerge combined package The additional CP/M software items include: 1 Z-Term for Apple CP/M Softcard 1 Osborne: Documate-Plus, Spellguard, Supersort, DataStar 1 Osborne Personal Pearl We also have a few packages for PCs: 3 Curse of Ra 2 Upper Reaches of Apshai 1 RBase 4000 relational database management system (DOS) 1 Borland Sprint wordprocessor (DOS) 1 Samna Plus IV wordprocessor (DOS) 1 Open Access (integrated package: graphics, spreadsheet, wordprocessing, and more) (DOS) 2 TK Solver (equation solver) (DOS) 1 WordStar (MS-DOS for TI Professional) +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ We still have a few books left from the large original collection. 1 CP/M Handbook, Andy Johnson-Laird 1 CP/M User Guide, Hogan (Osborne) (special Apple version) 20 Introduction to Wordprocessing (free for asking with order for any other items) 2 Database Management Systems, Kruglinski (Osborne) 1 Everyman's Database Primer, Byers 1 The Power of Multiplan 1 Micro Cookbook, Don Lancaster 4 Pascal, A Problem Solving Approach, Koffman 1 Introduction to WordStar, Naiman 1 Kaypro WordStar 4 Manual (DOS version) 1 The VisiCalc Book for the IBM PC, Beil 2 Osborne User Guide 1 Using the Osborne 1 Computer 2 Osborne User's Reference Guide 1 Osborne Executive guides collection (4 vols) 1 Osborne Start-Pak instuction kit with tapes 1 Osborne Guide to Understanding the Micro 1 set of Symphony manuals +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Among the more interesting items were a lot of accessories for the HP-41 calculator.

Message-ID: <10804@tamsun.tamu.edu> A few months back, I came to c.o.cpm with a problem: My QX-10 had just died! Thanks to the help I received from Wayne Sung (sung@concert.net) who did long-distance diagnosis with me via e-mail, and George Worley, a fellow QX-10 enthusiast and SysOp of "PIC of the MidTown" BBS in Houston, TX [(713) 527-8939] who loaned me his Technical Manual, I now have the CPU back up and running just fine. The problem turned out to be bad filter capacitors in the power supply. I had first come to c.o.cpm asking bout the hard disk that died on the QX-10. That project is now back on. I received a second drive mechanism from a fellow member of our very small Houston, TX CP/M user's group. I installed it and ran the ComRex ComFiler diagnostics and everything checked out. I then proceeded to format the disk. (The original mechanism refused to format.) After about 30 minutes the formatter declared ***DRIVE FORMATTED AND READY FOR USE***. Every- thing appeared to check out and I saved a couple of 0-length files on the disk. I then parked the heads and turned everything off. When I turned the system on again, the Hard Disk was dead. It would not read, write or format. NOTE: The recommended shutdown sequence demanded by the documentation is CPU first, then Hard Disk. If this is not generally accepted, I will happily disregard the manual. I have since had the opportunity to connect the mechanisms to a MeSsy-DOG machine where they format (low-level), partition, and format (DOS) just fine and they operate flawlessly. Unfortunately, I did not have the QX-10's hard disk software with me when last I had opportunity to check the mechanisms on the QX-10 itself, so I'll be doing that this weekend. I'll post my results.

It seems to be a CP/M box manufactured by a german company (dfe). But all I have is the hardware. NO floppies, no manuals, etc. Is there anyone out there, who can provide me with hints, documentation, software or even a working system disk? Description ----------- solid case containing - big power supply - main board with 2(!) Z80 CPUs - floppy controller card - 2 floppy drives 5.25'' and following connectors: - DB 9 (unknown purpose) - DB 25 seems to be a serial port - DB 37 for monitor and keyboard - DB 37 (unknown purpose) The german keyboard is like all other components in a metal case and has it's own Z80 CPU. I also have an additional board which connects to the bus and plugs between main board and monitor/keyboard. I found that this board containing one more Z80 ;-) implements a hardware based debugger (ever seen something like that?!) which I can use e.g. to trace the bootstrap. When switched on the box beeps, does its selftest and then prompts with "IPL:" for a boot device, which defaults to "D1". If I type "F3" or "F4" the corresponding floppy drive is activated and the head makes a little move before beeping again. Any ideas are welcome because I'd REALLY like to get this machine up and running.

You are mis-informed regarding most 8080/Z80 machines having the boot ROM at 0000. At least for those that run CPM - certainly the TRS80 is an example of a common machine for which your statement is true. If you can call BASIC the boot ROM :-) Anyway, most machines that run CPM have the boot ROM in high memory, usually at F000 or F800. Various hardware tricks are used to get the CPU to start executing at that address. My personal favorite was elegant simplicity itself, needing only an 8 bit buffer and a single flip-flop. Whenever reset was pressed, it set the flip-flop, which enabled the POJ buffer and disabled the normal data bus buffer. The 8 bits were forced to a NOP value, and the Z80 started cycling through the addresses. When the decode line for the BIOS ROM went active (the Z80 had stepped through every address from 0 to the first byte of the ROM), then the flop was reset, enabling the standard buffering to the CPU. It was particularly elegant because most other schemes require not only a higher parts count, but that the user must set *two* addresses when addressing the BIOS, one for the BIOS itself, and one for the POJ. Note that at 4MHZ it doesn't take long to step through a 64k address space one instruction at a time :-) The most brute force method requires lots of parts and is really terrible, IMHO, but I suppose is the most 'politically correct' method. It is probably the method that would be approved by most CS departments. :-) :-) It is basically a state machine that forces three bytes on the bus in response to the first three instruction fetches: a C3, a 00, and an XX where XX is set by some dip switch or jumper block. This literally is a direct jump instruction that starts execution at any 256 byte page in memory immediately after reset. There are a number of other schemes out there, I only described the best and the worst of the common implementations I have seen. -- del AKA Erik Lindberg uunet!pilchuck!fnx!del Who is John Galt? ------------------------------ Date: 14 Mar 92 23:15:36 GMT From: bobsbox.rent.com!gnat!cmcewen@rutgers.edu (Chris McEwen) Subject: Re: This must be a FAQ ( .CYM files) Message-ID: krish@vuse.vanderbilt.edu (P Krishnan) writes: > I just downloaded UUCP for CP/M from Simtel20.

Various hardware tricks are used to get the CPU to start > executing at that address. Whoa! Are we talking Boot ROM, or are we talking the BIOS? A number CP/M machines *DO* have boot ROM at 0000h. For example, the Xerox 820 series boots at address 0000 with the Boot ROM enabled, transfer the BIOS from slow ROM to faster RAM at F400 using a block move, then jumps to Cold Boot, which swaps out the the ROM, leaving RAM at the lower address. Your "cycle through the addresses" is not at all elegant, though it is a cheap and dirty solution that works. The above method I listed is not "brute force" as you might have sugested. It simply needs an additional flip-flop (in I/O space) to determine if the lower memory bank is ROM or RAM. The Z-80 takes a lot less time to block move a few K of BIOS code, than to cycle through all the address space. For that matter if you wanted to keep the BIOS in ROM, it is real simple to build in banked memory. When you power up (or reset), the ROM is at both locations 0000h *AND* F000 (or F800). You then jump to Cold Boot, and part of that swaps out the Shadow ROM at 0000 and puts RAM in it's place. Again, this is simple, "elegant", and requires little hardware. ~ Mike (Sprague.Wbst311@Xerox.Com) ------------------------------ Date: 11 Mar 92 23:50:46 GMT From: world!bmarcum@uunet.uu.net (Bill Marcum) Subject: Re: Televideo 803H information wanted Message-ID: In article larry@lfergus.UUCP (Larry Moore) writes: >Managed to luck onto one for a reasonable price, and since I have >a spare DS1612E SmartWatch, thought I might use it for >initialising the system clock at bootup.

Even assuming all the ICs could handle the increase in >speed, wouldn't any of the firmware be time-critical andd need to be >re-written? I'd be very careful to run diagnostics for several hours before trusting the machine at a higher speed. (diagnostics that test all CPU functions, memory, and as much of the interface chips as possible). When I was designing a Z80 system, I knew that I had 2 cycles for memory read/write, 1.5 for opcode fetch so I bought chips that would just meet that timing (allowing for memory decode). Go any faster and the memory would probably start giving some garbage results but only for some locations. The peripheral chips may act strange. The Zilog I/O chips need to see the 2 byte sequence for "RETI" (return from interrupt) to reset the interrupt daisy chain. If they miss that sequence at the higher speeds, the I/O system may hang. So try it, but carefully and be aware that ANY part of the system may react. BIOS wait loops are possible, but I had hoped that the CTC (counter timer circuit) was used for timing, particularly since the Z80 was so nicely interrupt driven. - jeffj jeffj@synsys.uucp synsys!jeffj@uunet.uu.net ------------------------------ Date: 16 Mar 92 17:19:05 GMT From: micro-heart-of-gold.mit.edu!wupost!cs.utexas.edu!utgpu!utzoo!henry@bloom-beacon.mit.edu (Henry Spencer) Subject: Re: Z80 chrystal upgrade ???

Even assuming all the ICs could handle the increase in >speed, wouldn't any of the firmware be time-critical andd need to be >re-written? Way back when, I was working with a terminal server that used a Z80 as the processor. In order to get 19.2Kbaud, full duplex on both ports, we had to upgrade to the 8 Mhz Z80 processor. At the time, it was brand new and we received some of the first engineering prototypes. It was a direct replacement and none of the code had to be rewritten. Anything timing related was handled in hardware and no timing loops in the code were used. However, we did run into one major problem. It seems that although Zilog made a processor that ran at 8 Mhz and all of the other supporting electronics could handle that rate, Zilogs DMA chip would not run any faster than 4Mhz. This was a problem. In order to make things work we had to develop a sort of automatic transmission that would shift the clock rate down from 8Mhz to 4Mhz everytime we accessed the DMA chip. It worked liked a dream and everyone was pretty proud of the accomplishment and when we showed it to Zilog they asked, "Why would you want to do that?", response "Because you don't make an 8Mhz DMA!", ...."oh"...

Message-ID: <1992Mar18.073748.3259@st-andrews.ac.uk> I have had a number of Z80As running at 6 or even 8 Mhz. At times I run out of Z80Bs and have to use a Z80A as a temp measure. The problems you can get tend to be random, infrequent and usually terminal. In most cases if a Z80 is to fail at the new speeds, you find out in 3 or 4 seconds after trying it. One point to note. If the clock speed is incresed, the actual speed of a system may be slower. Someone said recently that they designed circuits using memory that just met the Z80 timing specs. If you are using wait states in the cicuit, a small increase in speed may actaully require you to add an entire wait state and hence slow the system down!!!. A small point I know, but if you have to find this one out the hard way it takes hours.

I would not expect ARUNZ to be doing anything with interrupts, but I have not looked at the source code yet to check. Are you perchance now using the type-4 version of the program? All type-4 programs have DI and EI instructions as part of the address relocation code in the type-4 loader, which occupies the second record of the COM file (bytes 80H to FFH). I believe that this code cannot work with interrupts enabled because of the way it uses the stack pointer. If you want interrupts to be disabled at all times, then you can simply replace the EI opcode with a NOP (00H), and your problem should go away. You will have to do this with any type-4 program you intend to use. The easy way to do this would be to take the T4LDR11.Z80 source, take out the EI opcode, assemble it to a new HEX file, and MLOAD it over all type-4 programs before you use them. Alternatively, you could simply stick with the type-3 versions of the programs. I should point out that versions 3.3 and later of ZCPR also have parts of the code that turn off interrupts and then reenable them. This occurs in the part of the code that asks for directory passwords.

It was designed before the IBM PC had become an industry standard and therefor is not IBM compatable. The differences are in the way it handles the screen keyboard and disks. The disks are RX50's and are 80 track 10 sector single sided for 400K bytes each. A driver exists that will allow an IBM AT class computer to read and write the RX50 formated disks. At one time there were Rainbow support groups all over the country. There are still many of these units being used.

You are mis-informed regarding most 8080/Z80 machines having the boot ROM at 0000. At least for those that run CPM - certainly the TRS80 is an example of a common machine for which your statement is true. If you can call BASIC the boot ROM :-) Anyway, most machines that run CPM have the boot ROM in high memory, usually at F000 or F800. Various hardware tricks are used to get the CPU to start executing at that address. My personal favorite was elegant simplicity itself, needing only an 8 bit buffer and a single flip-flop. Whenever reset was pressed, it set the flip-flop, which enabled the POJ buffer and disabled the normal data bus buffer. The 8 bits were forced to a NOP value, and the Z80 started cycling through the addresses. When the decode line for the BIOS ROM went active (the Z80 had stepped through every address from 0 to the first byte of the ROM), then the flop was reset, enabling the standard buffering to the CPU. It was particularly elegant because most other schemes require not only a higher parts count, but that the user must set *two* addresses when addressing the BIOS, one for the BIOS itself, and one for the POJ. Note that at 4MHZ it doesn't take long to step through a 64k address space one instruction at a time :-) The most brute force method requires lots of parts and is really terrible, IMHO, but I suppose is the most 'politically correct' method. It is probably the method that would be approved by most CS departments. :-) :-) It is basically a state machine that forces three bytes on the bus in response to the first three instruction fetches: a C3, a 00, and an XX where XX is set by some dip switch or jumper block. This literally is a direct jump instruction that starts execution at any 256 byte page in memory immediately after reset. There are a number of other schemes out there, I only described the best and the worst of the common implementations I have seen. -- del AKA Erik Lindberg uunet!pilchuck!fnx!del Who is John Galt? ------------------------------ Date: Tue, 24 Mar 1992 08:05:51 PST From: Sprague.Wbst311@xerox.com Subject: Re: Xerox 850 Document System Message-ID: <"24-Mar-92 11:05:51 EST".*.Michael_D._Sprague.wbst311@Xerox.com> > I'm told that a Xerox 850 Document System may be cpm-based. > Can anyone out there confirm this (I've not touched one)?

Contrary to what at least one persone believes, the boot rom on the Televide is at zero. It's accesses by writing some code in the top 16K of memory that outputs zero to port 13h, this pages out the TPA and pages in the boot rom. Output a 1 to port 13h to page the TPA back in. As for where you'd put this code, I've got a couple of suggestions: On a standard 803 (dunno if this'd work on an 803h), BDOS starts at (I think) CA00H - this means the space from C000 to C9FF is available. The other place that is handy for hiding things away is the GSX buffer: this is 128 bytes long, lives in the BIOS (EA00H or higher) and is pointed to by the word at FF00H. Take a look at the standard 803 QTERM code in QTERM.Z to see how to shove something into that space. (David Goodenough or some other TeleVideo guru?) Dammit - I swore I wasn't going to be famous.

For example, I had to move the refresh signal on my SDS D-Ram boards, plus another signal (XRDY or PSYNC, I think). NorthStar RAM is dynamic, and refreshing is done in a bizzare fashion. DMA disk controllers (I think) won't work. You must use a wait state based controller. I'm doing this from memory, so take a good look at the schematics. The NorthStar ridiculously puts its boot PROM at E800. Make sure that memory stays free. You can put stuff above it, say at F000, but don't stomp on the boot PROM. It is on the NS Disk controller and takes about 256 (or 512, I forget which) bytes. This weirdness limits you to a 58K CP/M. Your re-written BIOS may cut that down a little further. I suggest moving the BIOS into the EPROM socket on the CPU card and putting above your CP/M at F000. All in all, an excellent S-100 beast. My sincere Thanks to Curt Mayer. ... gng ------------------------------ Date: 27 Mar 92 06:05:33 GMT From: baron!baron!pnet07!donm@nosc.mil (Don Maslin) Subject: Re: OASIS (sp?)

Message-ID: <11493@tamsun.tamu.edu> For those who have been following my QX-10 saga, I have more to report on my hard disk problems. I said before that the mechanisms I have work just fine on a MS-DOS machine with an Adaptec ACB 2010A controller. When operated under the ComRex system with WD1002-5D Rev. Y controller, the drive passes its seek test (very audible) and the standard diagnostic software claims that the controller passes all of its register tests. Attempting to format the drive, however, results in the drive being unreadble by anything--Epson or MS-DOS machine. I got different format and verification programs from a fellow QX-10 owner whose system uses exactly the same hardware. this program does about the same thing. It sits on each cylinder for about 17 seconds, then moves on. During the verification phase, it returns the following error message: WD1000 ERROR = 10 CYLINDER cccc SECTOR ss HEAD hh ALREADY LOGGED Starting with cylinder 0001, the message at the end is only 'LOGGED' for the first sector of head 0 only. It repeats the message(s) above for the first 5 cylinders after which it aborts. The stand-alone verifier returns the same message(s) except says 'WD1002 ...' Can anyone tell me what ERROR = 10 might be and the significance of the different '[ALREADY] LOGGED' messages. Thanks for the help. John D.

The files with z in them are "crunched" using LZW techniques, very simular to UNIX compress. The ones with the "q" are "squeezed" with Huffman encoding There are many programs that deal with these files look in the same place you found the files for an area labled "starter" or LIB-ARC or something like that. The programs I use are UNCR.COM and USQ.COM or NUSQ.COM . Most of the PD areas on the networks or BBS's have a "STARTER" area where you find uncompressed and unarchived versions of these programs along with introductory text that explains how to get started. -------- Ray Brown rjbrown@giamem.enet.dec.com or rjbrown%giamem.enet@decwrl.dec.com or decwrl!giamem.enet!rjbrown --------- ------------------------------ Date: 30 Mar 92 11:16:54 GMT From: world!bmarcum@decwrl.dec.com (Bill Marcum) Subject: Re: .tzt .tqt Message-ID: In article <1992Mar29.081123.15496@uwm.edu> mrdunn@csd4.csd.uwm.edu (Michael Robert Dunn) writes: >I'm just starting to download some cpm software and I noticed a bunch >of files with a z or a q in the middle of the extention.

(Note to Usenet newcomers: FAQ means Frequently Asked Questions, and almost every newsgroup has a list of these.) Files with .?q? filenames are "squeezed" (a very old form of compression). ?z? files are "Crunched" (Names ending with AZM might be either crunched, or written for the Z80MR assembler). A newer form of file compression is produced by a program called CRLZH, and has file names ending with .?Y? . Any of these types of files can be placed inside a LBR file. There are a few different programs to extract them. My favorite is LT30.

I mean, if interrupts aren't enabled, it should detect this and not enable them when it gets through the critical section of the code. Bridger Mitchell had some examples for doing this in The Computer Journal, Vols. 36 & 37. Be sure to see both articles, because the second has a work-around for a Z80 that the code in the first article. Specifically, if an interrupt occurs while your code is checking the interrupt status, the Z80 will wrongly report that interrupts are disabled. On the other hand, the code to do this might not fit, either in the Type 4 header or in the command processor. -- Jeff Wieland wieland@ecn.purdue.edu ------------------------------ Date: 00:35:54 GLT TUESDAY 03/31/92 From: K.MAGOUTIS i am looking for a brand new or good-conditioned used OSBORNE 1 machine + software, on sale in the U.K. Any offers directed to cacz1107@grtheun1.
