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

Bernoullis were more or less predecessors of Zip drives, technologically speaking. I may have a Mac SCSI driver around here somewhere for these things or you might try the Iomega website. SML

Inland ProBackup 500 sought (pinouts or software)

by Edward.Tillman＠valero.com

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. Also, you might heck with C|Net (Download.com), ZDnet, or similar pages. If they don't have it, they can likely point you in the right direction... Cheers!

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

I used to use this email account for another purpose. I had this email account set for the "name" field to be "ssj152", in a misguided attempt to maintain SOME privacy.

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.

Interested in documentation, user guides, programmer manuals, brochures, advertisements, etc. If someone actually has one or more of the hardware components that would be very interesting. IBM announced it in 1971 with a big sale to Merrill Lynch that may never have been fully completed. Thanks in advance, - Jim Jim Keohane, Multi-Platforms, Inc. "It's not whether you win or lose.

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.

Can a TU81+ be connected to a TU80 controller?

by kees.stravers＠iae.nl

I have a VAX 11/750 machine with a TU80 controller in it. I also have a TU81+ tape drive. I know the TU81+ is supposed to be connected to a KLESI controller. But can a TU81+ be connected to the TU80 controller (only doing 1600 then of course)? And if not, does anyone have a Unibus KLESI for sale?

Ultrix v4.3 install on mVaxII

by Fred.van.Kempen＠microwalt.nl

Short answer (top-posted, sorry): i have a kit and a readme somewhere which allowes net.boot and net.install of Ultrix off any machine that runs Unix. I even ported it to NT :) (just for phun, obviously). Basically, you need: - 200M disk space - packet filter in kernel - my new MOP Server That'll boot anything, including the Ultrix install set.
