Greetings -- I have a small program (about 3K lines of C) which I want to rewrite in Z80 assembly language in order to reduce the code size. The target system is a Kaypro 10, 64KB RAM, CP/M 2.2. In its C incarnation, the program *will* run but frequently runs out of system memory. The program is designed around multiple dynamically allocated linked lists which expand and contract as the (interactive) program is used. I've done little Z80 assembly programming (a number of small utilities, all of which were < 500 lines of code) but I've already written and tested *almost* all the low-level functions (console, file, & printer i/o) which the program requires. Except . . . how do I dynamically allocate memory? I don't see a CP/M function call to allocate or free memory. Does such a function exist, and if so, what are the details? Lacking such a CP/M function, how do I write replacements for malloc() and free()? It has to be possible or the calls would not exist in the library of the compiler I used to build the C program. TIA for any hints -- Glen 0/0

Inland ProBackup 500 sought (pinouts or software)

You know the brand name of the UPS: There's likely freebie software out there on one of the .dll catalogue pages, if you know the make/model/series names/numbers.

Inland ProBackup 500 sought (pinouts or software)

by julesrichardsonuk＠yahoo.co.uk

Message: 23 Date: Sun, 26 Jan 2003 20:32:22 GMT From: pete(a)dunnington.u-net.com To: cctalk(a)classiccmp.org > >From a previous life, I have a perfectly fine working UPS. ... > Would anyone happen to have windows software for it? As a last resort, how > standard is the DB9 pinout (IF I can find the pinout, no luck there > either)... I'm wondering if I can use just about any UPS software for it. I guess you can get a meter on the various port pins and simulate various failure modes to work out which pins signify what - if the UPS is non-intelligent and just uses various serial port pins to signify conditions. If the UPS forms some sort of protocol with the host you have a bit of a problem! I seem to remember setting up a linux box with an unknown UPS years ago, and doing just that, but of course getting a UPS to work with Linux is probably a little easier than Windows as you don't need any custom software. I expect if you can figure the UPS port out and find out what the UPS software (whichever you choose) on Windows needs then you can wire up a cable and everything should work fine. have a look at: http://www.tldp.org/HOWTO/UPS-HOWTO.html that says that a lot of intelligent UPSes can be operated in dumb mode, and also gives specs for a few units. Probably worth a read even though it's for Linux. cheers Jules __________________________________________________ Do You Yahoo!?

Can a TU81+ be connected to a TU80 controller?

I thought that TU80 had a Pertec formatted interface while TU81 (plus or not) had LESI interface, i.e., two totally different interfaces. They are both CDC Keystone tape transports and I think it's one board inside that provides the interface and thus differs. But if you want to try swapping CDC Keystone logic boards, you are on your own. MS

System/36 whining and begging...

by ceby2＠csc.com

Folks -- Thought I'd continue my unreasonable begging from the previous note back to Bill. I'd like to take on a little project of creating archival images of S/36 media. I've made a duplicate of most of what I own on fresher 8" stock. But I don't think that's a long term strategy for avoiding the inevitable ravages of media corruption. What I had in mind was something like a 'dd' dump of each disk that could be reloaded to fresh 8" media when required. I haven't given this too much thought so bear with me.... I'm working on a list of questions and puzzles to accomplish this goal.The first obvious problem is media to hardware integration. If memory serves, I read somewhere that IBM used an oddball disk format (Sellam, you might know this). 8" Shuggart drives come on the market from time to time but, would they, using low level drivers, be able to make a physical block by block copy of IBM S/36 disk data? The second problem is hardware to hardware integration. Has anyone had luck integrating a 8" drive with a more recent machine? And what are the alternatives? I presume this could be done on DEC hardware and then sent to any open platform over a network connection. Has anyone gotten an 8" floppy operating under an Intel based Linux host. That would seem the obvious media transfer station because of the wide range of hardware compatibility. Once these first two steps are done, any basic disk utility ought to make short work of creating binary dumps. An alternative approach might be to copy the disks directly on the System/36 host using platform native tools then sending the file across some form of network connection. The problem is I haven't a clue how that would need to be done. I've never read any low level API for S/36 as a platform. IBM seems to have kept anything harware layer proprietary. Any and all thoughts welcome. Thanks, -Colin ceby2(a)csc.com Senior Consultant, National Performance Engineeering Practice CSC Consulting.

Xilinx purge this time

by aw288＠osfn.org

Thanks for all that asked for EPROMs - I think I could help about half of you guys out. I still have *lots* more, but not many oddballs. Anyway, I have a small pile of FPGAs - (6) Xilinx XC2018-70PC68C and (1) Xilinx XC3042-70PC84C. Pulls, PLCCs, good leads. Anyone need this pile for $6.00 - and that includes shipping ConUS! And yes, I take Paypal. I also have buckets of old Lattice GALs, if anyone wants them cheap, to erase and reuse. William Donzelli aw288(a)osfn.org

HP1000's

by avickers＠solutionengineers.com

Wow, what a day... Today (erm, well, yesterday now), I have collected 2x HP1000 machines (c/w 4 free-standing disks & 1 line printer), one 700 (can't remember if that's a HP1000 model or not), and a whole stack of tapes & disc packs & documentation. Woohoo! Thanks Tim! Sadly, we weren't able to save a 3rd HP1000, as the van was already showing serious signs of being overloaded with the gear that was in there - backing into my shed, it was actually running over its own mudflaps... I forgot my digicam, so there's no pics yet. Hopefully, when I'm up north next I'll take a few snaps (and try to get at least one of the boxes booted). And now, I'm officially knackered, g'night! -- Cheers, Ade. Be where it's at, B-Racing! http://b-racing.com

Not very rare or very valuable. Ebay has an auction for a monitor //c (Item #2302608656), currently at $10.00 US. An Apple //c is also for auction on eBay (item #2302671100), currently at $26.00 US. This will give you a sense of the computer's worth. I am sure that a unit with lots of accessories, software, etc. and in excellent condition, will bring more. Stuart

Slightly OT? Squished Boxes..

by dholland＠woh.rr.com

Perhaps this is slightly off topic.. (If so, someone say something, and I'll hush..) I was down in the basement when I stumbled across my box of moldy old software, (mostly pre-1995 IBM PC oriented stuff) and thought to myself, "Hmmm, maybe I should put these up on a bookshelf instead of letting them rot down here." Anyways, upon pulling them out of said box, I noticed a number of the boxes had become fairly squished/dented/etc.. (Next time pack them better. :-/ ) Any body ever try to "restore" old software/computer boxes? Got any tips? Thanks, David

wanted: Multia/UDB spare parts

by freddy＠kotelna.sk

hey folks, I've just missed a great ebay auction for Multia spare parts, does anyone have some multia accessories they might sell/trade? I'm looking mainly for floppy drive with cable and pci riser card with 2.5" connection (and external scsi cable). My multia has also burned videocard, so eventually a whole multia box (with the above included) might be of use as well. If your box doesn't have battery or burned the chip on the botton (common problem, afaik), this doesn't really matter, I'm able to fix this.

ibm sys/36 5360 basic needed

by ceby2＠csc.com

Bill -- I have most of the System/36 stuff... except the languages, sigh. You wouldn't happen to have any of the SSP on 5.25" would you. I have a 5363 I've never successfully IPL'd . And while I'm turning your request for assistance on its head... you wouldn't happen to want a 5360 would you? I have one in need of a good home. I don't even have a garage so I'm paying storage for the beast (2 tape drives, 2 printers, expanded main cabinet with additional disk platters and the magazine version of the 8" floppy). Maybe I can be more helpful if you have other S/36 needs in future. I have a lot of the books and even a few already scanned to PDF. While I'm begging, I don't suppose anyone out there has the Office suite for S/36, or any interesting applications? Or maybe someone wants to be free of a 5364 (a little easier on the electric bills than the 63, 62 or 60). My systems only have SSP, and I have a perverse desire to get some use out of them. -Colin ceby2(a)csc.com Senior Consultant, National Performance Engineeering Practice CSC Consulting.

Inland ProBackup 500 sought (pinouts or software)

by jwest＠classiccmp.org

This is probably OffTopic(tm), but I thought folks here might be able to point me in the right direction. >From a previous life, I have a perfectly fine working UPS. The brand says "Inland - by ABI International". Model is "Probackup5000", part number is 19500. It has a DB9 serial port on the back for interfacing with a host to notify it of loss of ac, impending shutdown, etc. However, I don't have the software (for Windoze) that came with it. I've googled for hours, and can't come up with anything on this exact unit. Would anyone happen to have windows software for it? As a last resort, how standard is the DB9 pinout (IF I can find the pinout, no luck there either)... I'm wondering if I can use just about any UPS software for it. Any advice? THANKS!

Seeking LaserJet IIISi I/O card

by erd_6502＠yahoo.com

I have asked in the past about a replacement card for my HP LJ-IIID with little success (they are apparently somewhat rare). Several people offered me ones that did not physically fit. Well now, I have a *newer* old HP printer, an HP LJ-IIISi that takes the square interface cards with the white/grey 3-row connector. Unfortunately, the printer I got from OSU surplus (which seems to print just fine) only has this truely ancient C2059A integral print server - no serial or parallel, Novell only. :-( Worse, the firmware is particularly obsolete and deprecated by HP. So... if anyone has a spare interface card, I'm interested. Two, in fact; one for me and one for a friend who needs to hook another IIISi to his OS X Mac. The printer is on-topic (mine was manufactured in 1991) at least. Let me know cost/part numbers/etc off-list. Thanks, -ethan __________________________________________________ Do you Yahoo!? Yahoo!

Harvard Mark I Manual On-Line

by blstuart＠bellsouth.net

I haven't seen this announced here, so for those of you who don't read alt.folklore.computers, Al Kossow has made available a scanned copy of the Manual of Operation for the Harvard Mark I. It's at: http://www.spies.com/aek/pdf/harvard/MarkI_operMan_1946.pdf Be forewarned, however, it's big-about 43Meg. I have a real soft spot for this one. Back in college, I was wandering the library stacks one day looking for something interesting. A book caught my eye. It was a black hardbound book about 2 inches thich with the simple title Manual of Operation. Of course, my curiosity was piqued; I just had to take a look. I'd never heard of the Mark I, but I was absolutly enthralled. I credit that find with much of my interest in the history of computing. By the way, anyone know of an emulator for the Mark I? Brian L.

Subject: strange things to do with your IBM System/3x

by n8uhn＠yahoo.com

after reading the subject line, i thought the article was going to be about sledge hammers or making them into wet bars (yes on the web - someone has made a vax rack into a wet bar). all the ibm languages were available for the sys/34 and i have all of them basic,cobol,rpgii and fortran. i even have diag and ssp (system support program, ibm's os for sys3x) the two sys34's i have both have bad control storage cards - a typical problem with 5 years in cold storage. otherwise i would be playing with them and not this basic less sys/36. the ssp and all languages for the sys/34 are not compatable with the 36. i did find the 3270 emulator for the 34 and i may have pc support for the 34 - i know i have both for the 36. i found out that one of my 34's came from the local collage - which explains the "funtime" diskettes. they are programs is basic that have printfiles for many "pic's" and football and other text based games.

I know I have COBOL and SSP and some other > crud... When I was in junior high school, my friend Doug got a job working on RPG code on a System/34. In his spare time, he translated ADVENT [*] from PDP-10 Fortran to RPG II [**] to run on the System/34. I don't know if there existed a Fortran compiler for the System/34, but if there was, his employer apparently didn't have it. COBOL would actually be a more reasonable language [***] into which to translate ADVENT, and there was a System/34 COBOL compiler. All of the text-handling code in ADVENT is non-portable, because back then FORTRAN didn't have reasonable support for arrays of characters. The number of characters that would pack into any given numeric type was implementation-dependent. On the PDP-10, that was five 7-bit ASCII characters per 36-bit word, with one bit left over. I think Fortran 77 fixed this problem, by defining an actual CHARACTER type. Unfortunately I haven't been in touch with Doug in over twenty years now; I have no idea whether he still has a copy of his RPG ADVENT. Which is a shame, because it would be nice to try it with the Eraseerhead RPG II compiler, which is GPL'd: http://rpg.eraserhead.net/ Eric [*] The original Colossal Cave Adventure game by Crowther and Woods, written in Fortran for the DEC PDP-10. Named "ADVENT" because the TOPS-10 operating system only allows for six-character filenames in SIXBIT code, which does not include lower case. [**] Or maybe it was RPG III. I don't really know what was available on the System/34 back in the late 1970s. [***} I'll bet you never expected to see "COBOL" and "reasonable language" in the same sentence, without an "isn't" between them. :-) Now I'm not saying that I *like* COBOL, but there are definitely some things that it is better-suited for than Fortran IV. __________________________________________________ Do you Yahoo!?

But if some weird system does require a special syscall, I can bet that dd on *that* system will make it. On each system its native dd utility will always do the right thing, as opposed to some special program ripped out of a 2.11BSD distribution and used for something it was never intended for (to write dist tapes for a completely different OS).

Grundy Newbrain

by toring＠inet.uni2.dk

Hi, I have an old Grundy Newbrain AD computer which doesn't work. The machine powers up with random chars in the built in anode display, but doesn't respond to keypresses. I used the machine some 20 years ago, and when I put it away at that time it was ok. I've checked the voltages at the 4116 RAM's and they are ok (+5, +12 and -5 volts). The ripple is also within reasonable limits. I don't have the schema for the machine so right new I'm pretty lost. Is anyone able to help me out? If so, please answer directly at my email address.

Quasijarus 4.3BSD on 1600bpi magtape

by Fred.van.Kempen＠microwalt.nl

> > > Yes. Use maketape from the 2.11BSD distribution. > > I strongly advise against this approach. > Well, I had to use some programm to write the tapes, dd(1), > maketape, or somthing else. Indeed. There is *nothing* magical about making tapes from selected files. What you have to keep in mind are: - select the correct tape boot blocks (MT, TK etc) - grab the correct kernel and/or RAM disk image - use the right blocksize for the above "file" (usually 512bytes) For the remaining files on the tape, blocksizes vary between OSes, and can be anywhere between 512 (old systems) and 10K (UNIX tar files). The key issue is to generate a magtape file marker between the individual files, so the tape handling software knows where a file ends. The block size and tape marker generation are done correctly by the Maketape program. If you want to do it manually: - grab the first ("bootable") file for the tape, and dd it to the tape: dd if=bootfile.img of=/dev/ntape bs=512 this copies "bootfile.img" to the tape, using a block size of 512 bytes, and when done, it will write a tape mark and **NOT** rewind the tape ("ntape" - can be /dev/nrst0, /dev/nrmt0h, /dev/ntk0, etc.) - copy the other files to the tape: dd if=nextfile.foo of=/dev/ntape bs=10240 which copies "nextfile.foo" to the tape, using a block size of 10240 bytes (common for UNIX tar files) and when done, writes the tape mark, and NOT rewind. - when done, write a tape mark and rewind the tape: mt -f /dev/ntape weof mt -f /dev/ntape rewind where the first command (Write EOF) is optional, as most UNIX systems do this automatically when rewinding a tape in write mode. This creates a magtape in the right format for booting. Tools like the Maketape program do this as well, based on a small description file which tells it what goes where and such. > > dd if=stand of=/dev/nrmt0h bs=512 > I learnd that the bs= parameter of dd doesn't set the block > size of the tape with an ioctl, it is only the buffersize > parameter that is used in the write(2) syscall. Correct. The 'dd' program **does not** set the physical block size of the tape device, as it is a generic block/deblock tool, and has no knowledge of devices whatsoever. It sets the block buffer size(s), on which the READ(2) and WRITE(2) system calls are based, which in turn tell the tape device driver what the block size is to be. This only works in the "raw" mode of tape devices, by the way- always use the 'r' device file of a tape unit when doing the above. Cheers, Fred
