Hi, I am the proud new owner of an HP 85. Printer belts a little ratty but works fine. However when I attempted to Rew/Load/Cat any of the tapes I received with it I got a stall error. I cleaned the capstan which is intact, and did not fall apart, as I understand they tend to do. The tape motor spins fine when I pressed the tape sensor button inside and hit Rew. Finally after a bunch of attempts the tapes began to spin and I could perform the Load, Cat and Ctape operations. I still seem to get fairly frequent stall errors however. Do you think I need to replace the capstan? Can you get them (or the printer belts)anywhere, or should I use the silicon aquarium tube method mentioned in the archives? Any other thoughts appreciated. Eventually hope to hook it up to a floopy drive but need to find a mass storage rom. Also do you know of any good resources on the web for the 80 series as I haven't found a whole lot. Thanks, RH

6502 fans - the SBC-2 is about to have another run - order boards now!

by erd_6502＠yahoo.com

(Whoops... let's try that again with the editing *finished* this time... For those who haven't been to http://65c02.tripod.com/ , the SBC-2 is a single-board 6502 with the following onboard: o 1 MHz 65c02 o 32K of static RAM o 32k of EEPROM o 2 x 65C22 Versatile Interface Adapters (VIA) o 1 x 65C51 Asynchronous Interface Adapter. o Eight 16-byte address blocks decoded for I/O (3 used onboard) This will be the second run of boards. At the moment, Daryl has ten orders. The deadline is 15-Feb. Picture at http://65c02.tripod.com/sbc2.jpg Current cost breakdown is: (from Daryl's announcement) $26.20 per board $4-6 shipping US $4-14 shipping outside US $2 for the serial cable (The serial cable is a 10-pin IDC<->DE9M, like the kind you find on Socket3 and Socket7 PeeCee motherboards). No guarantees that more orders will hit a new price point, so if you have an interest in a compact CMOS 6502 SBC, write Daryl: 65c02(a)softcom.net Do it soon. Disclaimer: I have no affiliation with the SBC-2 except as a potential customer. -ethan

I saw you post 12-17-02 about Intel 1602

by dwightk.elvey＠amd.com

Hi One should note that the programming of the A parts is different than the non-A parts. The manual shown has the specs for the non-A parts ( these are really rare ). Most are either 1708A, 8708A or 4708A parts that are found now days. Signal wise, I believe that the non-A and A parts are similar. They made very few of the non-A parts.

Things FS (dec, ncd, sun, chips), and Info requested

by pat＠purdueriots.com

First, the question. Look for "SELLING" below for what I have 'for sale'. I've managed to pick up a TECMAR, Inc. "LAB TENDER COMP" card for the IBM PC (8bit ISA interface) but I don't have any docs on it. There's a total of 5 34pin headers on the card, a bunch of 7400 seris logic, an AM9513, AM8255A-5, 5xTL084CJ, 4xHEF4051BP chips, and 3x8switch dip-switches. Does anyone know what this is and/or have software/docs for it? SELLING + Digital SC008-AB, one with an "A" and one with a "B" on it, has many (maybe 20) TNC Jacks monted on it, some with 'terminators' on it. Does anyone know what this is? I'm intrigued by it. $5 each + shipping + Digital M8210 - 32kW (72bit words) MOS memory for a VAX-11/780. It's still sealed in an anti-static bag, so I assume it's in excellent condition. $5 + shipping + NCD 19c Xterminal, no cables. Uses a sync-on-green monitor, does color, has AUI/10Base2 network connectors, uses standard PS/2 style keyboard and a 9pin serial (pc-like) mouse. ** Based off of Motorola 88100 processor ** $10 + shipping + 4 x Sun SparcStation 5, 64MB RAM, CG6 framebuffer, 2GB Seagate ST32550WC hard drive. These are working, but don't have an OS installed for licensing reasons. I can install Debian Linux (base install) on them if interested (for free!). $15 each + shipping, also have some parts (lots of CG6's), email if interested. + 6 x Sun SparcStation 5 power supplies (PN 300-1215-02): ratings are +5V @ 25A, +12V @ 2.3A(Max 4A), -12V @ 0.25A max continuous 150.2W, max output <15sec 174.2W $5 each + shipping + Not really classic, but I've got a lot of RJ45->DE9-F cisco console cables, and 48VDC, 0.3A table-top 'wall wart' power supplies. I figured that they might be of some use to list readers, and wanted to do this before they go onto eBay. $5 for one + shipping, or make me an offer for >1. + VME Boards - have socketed chips that are re-usable: PE/IO: 1 x MC68881RC15A - math coprocessor 1 x MC68901P 2 x MC68230P10 - 68k 'parallel port' chip 1 x PAL16R4CN -\ 1 x PAL14L4NC --+- does anyone know if they're erasable? 1 x PAL16R6NC -/ 2 x D8293 --\ 1 x P8291A ---+-- Intel GPIB chips parallel ports: 2 x MC68230P10 n x 74LS00 series logic IC's net interface: 2 x MC68230P10 n x 74LS00 series logic IC's DMA interface: n x 74LS00 series logic IC's 68010 board: 1 x MC68010L10 4 x KM6264L-15 8k x 8 150ns SRAM 4 x M5L2764 8k x 8 EPROM 1 x 5.0688MHz oscillator 68000 board: mostly same as the 68010 board, except with MC68000P8 instead I also have a couple of prototyping (wire-wrap) VME boards. You can see everything I have at http://purdueriots.com/mvme/ including (fuzzy) pictures of the boards. I'd like to get $5 per board + shipping to recuperate my costs. I can do cheaper for large quantites. ** The CPU boards have custom-developed console 'debuggers' that use the RS-232 port on the CPU card as a console. They *require* that a PE/IO board be connected to the VME bus in order to 'initialize'. You could, of course get around this by replacing the ROMs. If (when) I get multiple offers, I'll try to choose fairly who gets the stuff, or divide it up if there's multiple people interested Thanks for listening!

Dunno -- that might be one of the Bulgin range? Or do you mean one in which the housing also looks a bit like three cylinders welded together, instead of a rectangular block with corners cut off? That's also an IEC connector, rated 2.5A. I've seen a couple of laptop power suplies with those. -- Pete Peter Turnbull Network Manager University of York

Yep. Go to www.powerbookguy.com and browse his site. I bought several things from him when I was refurbishing the Wallstreet I was given, and he was very friendly and helpful.

Strainge VAXserver 2000 card?

by Fred.van.Kempen＠microwalt.nl

All, A strange find today, in the pile of stuff-to-figure-out. See attached pictures. Its one of those little option cards that fit in the VS2000's "pizzabox" expansion unit. I have two of these machines, both have the box. One of the machines is a VAXserver 2000 (!), and that one had this card. One single flatcable going to the machine's mainboard (connector on the side of the mainboard, above the power supply) and it has the usual DEC 3-row connector on the outside faceplate. What's this? Serial line expander of some sort? The X.25 thing I heard about? Larger pictures available at 1600x1280 and 1280x1024. Cheers, Fred [demime 1.01a removed an attachment of type image/jpeg which had a name of VS2000-OPT-1_SM.JPG] [demime 1.01a removed an attachment of type image/jpeg which had a name of VS2000-OPT-2_SM.JPG]
