Everyone, Lee Felsenstein is giving a talk, signing autographs, etc. at the InfoAge Science Center (2201 Marconi Rd., Wall, NJ, 07719) on Sunday, July 1. at approx. 10:30am. Unfortunately he couldn't be here for VCF East 8.0 last month. But this is the next best thing! Lee is very friendly and looks forward to meeting many of his fans. I assume all cctalk'ers know who Lee is ... but just in case .... Lee is famous for his work at the Homebrew Computer Club, Community Memory, Processor Technology, and of course Osborne. He was even part of Berkeley's Free Speech Movement. There's a $10 "strongly suggested" donation per person for our museum.

Sorry for delayed response, vacation intervened. http://www.cloud9tech.com/ (no affiliation, other than as a highly satisfied customer) does market DriveWire for the CoCo3 running NitrOS-9. I have not (yet) used it, but they claim 115,200 bps on a CoCo3. There is a corresponding server that runs on the (Windows/Mac OS X/Linux) other end of the serial wire, and they claim TCP/IP and several dependent services (telnet, MIDI streaming to the server).

anyone need an oscillscope?

uh I might be having issues with it. I may have more opportunity to investigate over the weekend. Maybe Im doing something wrong. The voltage display in the upper left corner disappeared, as did the trace. Sorry. Stay tuned

S-100 board PCBs remaining

by LYNCHAJ＠yahoo.com

Hi There have been several requests recently as to what S-100 boards I still have on hand I have remaining: one S-100 Z80 CPU board PCB three S-100 6502 CPU board PCBs twelve S-100 Serial IO board PCBs They are $20 each plus $3 shipping in the US or $6 elsewhere. Please send a PayPal to LYNCHAJ at YAHOO.COM Thanks and have a nice day! Andrew Lynch PS the S-100 IDE V2 board PCBs are gone. The next PCB reorders will be the S-100 ZFDC (intelligent floppy controller) board PCBs, then the S-100 4MB SRAM board PCB, and the S-100 backplane PCBs in that order.

Mystery Panel

by silent700＠gmail.com

I received this 23" panel strip recently along with a large lot of unrelated (DEC) items. I've tried some creative googling but have been unable to ID it. I'm hoping somewhere here may have encountered it in their past travels. Here is a gallery of pics: https://picasaweb.google.com/102190732096693814506/MysteryTelcoPanel Whatever it came from, it appears to be hand-wired with great care, perhaps even a one-off for its particular application. I thought at first it was telco-related, rather than computing, being a 23" rather than 19" mount. That may still be the case. Or, it could be both, given the intersection of the two industries. So, do those panel codes stir up any memories here? -- jht

P800 boards

by camiel＠camicom.com

I've completed a list of boards in the P800 haul: CPU BOX 1 - labeled P859 . CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . MCU3 : 5111 199 77442 (Paper tape, serial control unit (partially populated)) . 2 x M128E : 5111 199 67592 (128Kx21 RAM) . MCU2 : 5111 199 78181 (Line printer, card reader control unit) .

AMA-8A : 5111 199 75318 (Asynchronous line multiplexer) . SLCU2 : 5111 199 69373 (Synchronous serial line control unit) CPU BOX 2 - labeled P859 . 2 x CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . M128E : 5111 199 67592 (128Kx21 RAM) .

BIGD2A : 5111 199 57852 (Big disk) The weirdness of Box 2 is - obviously - a second CPU in the same box. This can't be right. CPU BOX 3 - labeled P859 .

GPC : 5111 199 79382 (Custom card) Box 4 just looks wrong. I don't know what the CDD cards are, but there doesn't appear to be a CPU or memory in there. However, there are P856 CPU's in the spare cards box, and I found references to the P856 being able to use MOS memory as well as core, so all might not be lost here. EXPANSION BOX - E2 type (6 slots) . BIGD2A : 5111 199 57852 (Big disk) . MTCU : 5111 199 72467 (Pertec 9 track magnetic tape control unit) .

SLCU2 : 5111 199 69373 (Synchronous serial line control unit) . TIMER CARD : 4022 422 20091 Looks like I should be able to get a few systems going with these parts. There's also a second box with spare cards, having different formats. Some of these are double eurocard format, like those used in the P85xE systems. There's also a spare power supply for a P859 box, as well as a spare power supply for a P856 box. I'm interested in finding out more about the cards I couldn't identify, these are: . ? : 4522 107 62304 . 4 x CDD : 5111 199 7817X . FLDB : 5111 199 69667 . 2 x MX : 5111 199 79335 . TIMER CARD : 4022 422 20091 I'm hoping CDD means Cartridge Disc Drive, and that these are the controllers for the X1215 disk drives. The 2 8" floppy disk drives are CDC BR8A8A type, looks like they are 800KB double sided, double density drives. They're very dusty.

Mac IIci/IIcx/Quadra 700 PSU schematics?

by fraveydank＠gmail.com

I've recently acquired a Quadra 700 from eBay. The power supply seems to be dead in the water; no voltage whatsoever on any of the lines, including the +5v trickle. Before I go delving into finding what may be wrong with the supply, does anyone happen to have a schematic for the GE version of this power supply? There's one available from bomarc.org, but they only deal with physical checks and mail, which means it would probably be about a week before I got anything back. Likewise, if anyone knows common failure modes for this particular supply (the Astec one has a known failure in the +5v trickle with a known hackish workaround, but the GE supply has a totally different reference designator schema and possibly completely different circuitry), I'd be interested in hearing about it. - Dave

DD versus HD 5.25" floppy drives

by dgriffi＠cs.csubak.edu

I'm pondering putting 3.5" and 5.25" floppy drives in a single chassis along with a Discferret / Kryoflux. The 3.5" can be HD with no problem. I'm leery of the complications of DD versus HD 5.25" drives. If I bulk-erase a DD disk and write to it with an HD drive, might there be any problems when the disk is used again on a DD drive? Would simply formatting the DD disk be enough? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing?

Has anyone ever heard of theProtec Microsystems PRO-83?

by rdcoll＠hotmail.com

Hello everyone, I just joined this mailing list today on the advice of more than one vintage computing contact. I was wondering if anyone could tell me anything about the Protec Microsystems PRO-83 Z80 Single-Board Computer. I have conducted an exhaustive search of the Internet and found only two sites (one from a surplus store and a picture of it from a museum). I would appreciate any information available, especially information regarding the power supply and peripheral devices. Thank you very much.

Tekniques vol1-8 online (Tektronix 405x newsletter)

Some time ago I obtained a batch of the Tektronix 4050 series newsletter issues. I have scanned these and Al has put them up on bitsavers: <http://www.bitsavers.org/pdf/tektronix/tekniques/> I've also scanned a software catalog for 4050 series: <http://www.bitsavers.org/pdf/tektronix/405x/Supplementary_Software_and_Serv…> I have some other Tekniques related items, but they are collections of reprints of articles from specific issues of Tekniques that I've already scanned above, so I considered it redundant.

Copying 5.25 inch floppy disks

by tom94022＠comcast.net

I have just received several hundred 5?-inch FDDs which I would like to copy to modern media. They contain WordPerfect files Does anyone know a low cost copying service? The best I have found so far is about $5 per disk although I suspect I could negotiate a lower bulk rate. In the alternative, can anyone recommend a USB 5?-inch reader? Device Side Data's FC5025 USB 5.25" floppy controller (http://www.deviceside.com/) looks like a starting point towards a reader for about $100. Tom
