govliq: Gould Concept/32 model 32/67 & Kennedy 9-track

by ken＠seefried.com

From: Al Kossow > I hope someone can pick this up. Gould Series 32 machines are getting > pretty rare. I should have paid better attention. I'll be in Jax tomorrow morning and decided not to bring the truck. What software is still around for a Concept/32? KJ

Wanted: Corvus Z80 "Universal" Transporter

by alhartman＠yahoo.com

I used to work for a Corvus Distributor in Brooklyn, NY in the 1980's and never heard of this item. If you find one, I hope you post details on this list as I'd be interested to learn more about it. Al ---------- Steven Hirsch <snhirsch at gmail.com> Wrote: I'm still looking for one of the above. This was a daughterboard designed to sandwich between a Z80 and its socket. It carried the Corvus proprietary chipset and permitted any CP/M machine to become a client on their Omninet network. If anyone even knows who has one, I'd appreciate a lead. In a pinch, given good photos I can likely reverse engineer the PCB and build my own (have a slew of Apple 2 transporters to harvest the chips from). The device is mentioned in one of the Appendices to DRI's CP/NET technical docs, FWIW. Steve

Classic A/V equipment

by aliensrcooluk＠yahoo.co.uk

See a reply from Tore below regarding the video link he provided recently. You need VLC (available here: http://www.videolan.org/ ) or other compatible software to view the video (and audio). The current version 0.9.9 for Windows works pretty well (I love setting the speed to 1.9x for chipmunk speech!), though there is a slight bug with the time display on Windows 2K SP4 (it displays total time correctly, but time played/left is invalid!)

8 bit SBC with floppy controller for disk archiving [was: Xerox 820 system disks in Teledisk format?]

by lynchaj＠yahoo.com

Hi! I sent this message earlier but it seems to have gotten drowned in all the unpleasantness. Hopefully we can move on to something more constructive. If anyone would like to discuss disk archiving legacy formats with an existing low cost home brew Z80 CP/M SBC and Disk IO board I think the N8VEM project would make a great starting point. It does everything described by Jules and is common enough now to have a decent support base. There are at least one hundred N8VEM SBC owners so that might be helpful in using it to archive disks. It uses a standard Intel 8272/NEC 765A FDC with some extensions for use with formats other than the usual 5.25"/3.5" DSDD/DSHD. Especially when paired with an IDE CF adapter I think it would be a very useful tool. Thanks and have a nice day!

Commodore 1541? Actually, they'd done that one already. Think about the IBM 5100/5110 with the 5114 diskette drive unit. I don't think they even wanted to think about putting something like that on a "personal computer"... --Chuck -----REPLY----- Hi Chuck, Jules! At least in theory, the N8VEM SBC mated with its Disk IO board provides this capability right now. The N8VEM SBC has 512K SRAM for immediate storage, the Disk IO supports IDE and NEC765 FDC capability. Attach a IDE to CF adapter (several varieties of those have been demonstrated to work or just use an old IDE hard drive) for storage and use the SBC serial port for operator IO. Connect the SBC to the Disk IO board via a 64 pin DIN 41612 IDC connector and short 64 conductor ribbon cable for a nice and compact two board (stacked Eurocard) solution powered by 5VDC only. The SBC boots CP/M 2.2 from its ROM drive which could be easily augmented with CP/M applications to manage the floppy disk transfer functionality. I designed the system with something like this in mind and there are at least the beginnings of the software necessary to accomplish it. The Disk IO board even includes special control and data signal access for raw disk reads and 8" floppy drive manipulation if someone were *REALLY* ambitious. I spent quite a bit of time working on this design along those lines but the Disk IO was such a beast I rather burned out on it. Since the PCBs and parts are all available now if someone wanted to pick this up the hardware is essentially completed, some of the software, and you're most of the way there. It would "only" take someone with the desire to write the software to make this happen -- basically comfortable old CP/M and Z80 assembler. I've moved on to other things in the N8VEM project. Thanks and have a nice day! Andrew Lynch

Available PDP-11/35

by quapla＠xs4all.nl

Hello Christian, Yep, it's a BA-11 not an BA23 (it was Monday morning when I typed the msg ;) Otherwise it would indeed be difficult to mount the frontpanel onto it.

I think he may have meant "PDP-11/53" . . . assuming it is in a BA23 chassis. . .

Hello Pontus, It's near Arnhem, and it's to heavy to ship, unless you want to pay for it. BTW, the machine is not for free, I'll send an update to the list. Make me an offer if still interested but I'll wait for some time before it will go to the highest offer as I need the money for finishing our new house.
