Pictures are at www.ezwind.net/jwest named FD-X.JPG. These two 8" floppy drives are about 1" tall each. The model number on them is Mitsubishi M2896-63-02U Rev. G. Their functionality is unknown, but were pulled from a working system. They appear to be doublesided. Best offer....or they go to ebay. Jay

For Swap : HP 21MX E-Series

by birs23＠zeelandnet.nl

I am about to move and need to cut down on my collection a bit for now until I know how much space I really have. One of the items that has to go is a HP 21MX E-Series. I have no idea if it still works etc but willing to look at anything you want me to look at. The system is located in the south-west of the Netherlands and I prefer pick up, shipping might be possible but is going to be VERY expensive.

Apple ][ boards (mostly

by ard＠p850ug1.demon.co.uk

Sellam mentioned that Apple ][ Comms card the other day... Thinking I should have one, I went digging in the depths of my workshop and found a box of mostly Apple ][ cards. I am not really an Apple person, so perhaps somebody sould tell me what I've found... All are Apple ][ plug-in cards unless I state otherwise. Wildport Ltd 6522 VIA card. Contains a 6522 (Duh..) and a '04 only. Has a lenght of 26 way ribbon cable connected by a permanent transition connector, other end unterminated. Probably a user I/O card. MTL APC.1.1 (that's in the PCB etc, no other identification). Cotnains 6821, 6850, 1488, 1489, '04, 2-off '151, and a 4060. Also a 2.4576 MHz crystal. Ther's a 20 pin header with nothing plugged into it, and a 10 pin SIL header with a cable ending in a DB25-P connector. Obviously a serial card, the 4060 divides down the Xtal to give the baud clocks, these are selected by the '151s to give the Tx nad Rx clocks to the 6850. >From a glance at the board, it would appear one port of the 6821 goes to the 20 pin header, the other controls the 151s (baud selection). Note there's no firmware ROM on this board. Another MTL APC.1.1 Apple Super Serial Card II.6551 + 2316 + TTL + RS232 drivers. I think I recognise this :-) CCS Asynchornous Serial Interface Assy No 07710-0001A. Another RS232 card. Containss 6850, 75150, 75154 (RS232 driver and receiver), 8304, 2 PROMs, '09, '136, '03, 4702 (baud rate generator). 4 position DIP switch marked 'Baud Rate'. 26 pin header, presumably for an RS232 cable. Epson APL Board Unit G479501000-0. Nothing to do with the language, I think, just an Epson printer interface. Contains a 2708 EPROM + TTL. 16 pin header, presumably parallel printer interface. Wesper Microsystems Wizard IPI. Assy 80003601. Looks to be another printer interface. has an EPORM la=belled EPSON/G10X + TTL Sync Printer Inerface Card. Apple. TTL + 2 off 2112 RAM + ROM. Has a DE9 connector at the front edge. I think this is a Silentype interface. Mountain Computer ROMWRITERTTL + a couple of 555 timers + a 24 pin ZIF socket + discretes. Clearly an EPROM programmer. Apple/PC link interface. 2716 EPROM + TTL + buffers + M58725 (?). One 20 pin header near back of card. No idea! Advanced Text Systems P.001 6520 + a couple of '16s + space for more buffers. Had a bit of ribbon cable soldered to it, with a DB25-P on the end. No idea! Another Mountain Computer ROMWRITER MEMOSOFT Made In France. Contains 6850 + TTL. Also 3486 and 3487 (buffers?) never soldered in + space for passives and a 2716 EPROM. 6 solder pins at the front of the board, seem to go to the buffers. Maybe some kind of network card? ICE LTD Apple Cold Boot Adapter. EPROM + 6116 RAM + TTL. One 26 pin header that might go to ... P-DJ2-301-B Not an Apple card, this looks to be a hard disk controller. 26 pin header at one end, 34 pin + 2 off 20 pin at ther other, and a disk drive like power connector. Z80A + EPROM + 2 off 2114 + TTL + SCX6225NCM/V5 KONAN (what the heck is that?) + 8465 (data separator IIRC) PROG RWP 8255 + EPROM + 78S40 (SMPSU chip) + '158 + 28 pin ZIF socket. Another EPROM programmer board. ICE Multiplexor Host Adaptor 2716 + 6116 + TTL. One 20 pin header RML PIP card (nothing to do iwth the Apple ][). A 380Z board with 3 off Z80 PIO and a Z80 CTC + TTL on it. 50 pin RML 380Z bus header connector. Prototyping area. 2 off Videx 80 column (?) cards. Cotnain 46505 (CRT controller, 4 off 2114 RAM, 2 off EPROM + socket for another EPROM (char gen and firmware?), TTL Buffered Grappler+ (C) Orange Micro. 64K RAM (8 off 4864) + EPROM + TTL + a 40 pin chip (microcontroller?). 26 pin header (printer interface). Is this a printer buffer card? Microsoft Z80 card. Z80 + ROM + TTL. I know what this is.... Apple Clock Board. Maybe home-made (PCB is not plated-through). EPROM + 8253 + TTL. No external connections. Apple Parallel Interrupt Type 2. Looks to be the same origin as the last board.. EPROM + TTL. 10 pin header linked to a DA15 plug 2 off Communication Board. These aapear to the board Sellam was mentioning. 6850 + TTL + P2 PROM + 8304. 2 off Apple Parallel Printer Interface. TTL + P1 PROM. 20 pin external connector. I found the manual for this, so I know what it is (it's a centronincs-;like interface, the odd thing being that the busy line is an address input to the firmware PROM. The stnadard firmware goes into a loop waiting for the printer to go ready, when it does, the intructions read by the Apple are not the jump-round-the-loop, so it goes on and sends a characer). Watford Electronics 1770 module for the BBC micro (nothing to do with the Apple) Homebrew lightpen on stripboard with a 16 pin header connector. Presumably for the Apple ][ game port Wattford Electronics Sideways ZIF socket. PCB with a 28 pin ZIF socket and some resistor packs linked by ribbon cable to a 28 pin header. Presumably to fit in the 'ashtray' on a BBC micro to allow easy ROM swaping 2 of 'WORKSTATION' EPROMs, (C) University of Sussex. Probably for the BBC micro. Any ideas? A few more Beeb-related chips (Torch Z80 pack EPROMs, 8271, etc) Pracitcal Peripherals PROCLOCK. 6821 + MSM5382 (Real time clock chip) + EPROM + TTL. Oh, and a Lithium battery. Obvious what this is... Disk ][ Interface card. And yes, I know what it is... Heuristics 20A-1. TTL + 2 quad op-amps + 2 quad comparators + 2708. 3.5mm jcak socket. I think this might be a speech input card... Mountain Hardware Supertalker. TTL + PROM + 3418 _ 2 quad op-amps + LM380 audio amplifier. 3.5mm jack socket 'microphone input', 2.5mm jack socket 'speaker output). Speech I/O? 2 grotty dynamic microphones, probably for the last 2 card. Any thoughts? -tony

cool Apple ][ Clone Webpage

by chenmel＠earthlink.net

I was trying to settle an arguement by finding a link to an Apple 2 clone that a friend of mine used to have (an Orange Peel). I googled a few keywords and found this COOL website of Apple ][ clone hardware. http://www.apple2clones.com/ These are the folks who kept the Apple legal department busy before Apple got all 'look-n-feel'y and sued Microsoft and HP. Just thought it was cool and interesting.

Giveaway: many Digital esp VAX + other workstation / microcomputer + peripherals

by tgarcia＠hivemind.org

Hello all, A private collector is giving away most of his computer stash. Stuff marked (*) is possibly already claimed; other stuff probably isn't, so make your free claim. There is a risk of stuff getting trashed, which none of us want happening - see "points" below. = QBUS-based VAX (nice) = 4 x MicroVAX 3400 - ok, what we have are 4 x BA213 cabinets, filled with many cards including processor+memory (KA640), and a huge pile more of QBUS cards, which will be catalogued separately. Millions of DESQA and other Ethernet cards are certainly apparent. I know at least two of these have 110V supplies fitted, but I also think there are 240V supplies lying around somewhere. Some have bulkhead panels in need of cleaning up where the battery has misbehaved. 2 x VAX 4000-500 - similar comment on the bulkheads, otherwise some nice beasts :-). (* at least one of each of the above taken) 2 x R400X - expansion boxes (*) BA215 = QBUS-based VAX (cabinets only in various states of undress) = 2 x BA123 - contains parts of a uVax II, not looking healthy 3 x BA23 2 x BA23 third-party clone = Desktop VAX = 2 x VAXstation 3100/38 2 x VAXstation 3100/76 VXT 2000+ 12 x MicroVAX 3100/30 6 x MicroVAX 3100/20 or 20e (were the things below uVAX or VAXstations??) 1 x MicroVAX 10 (*) 2 x MicroVAX 2000 = Other Digital computers = PDP-11/34 - with front panel, boots to ODT, no hdd/floppy (*) DECmate III (PDP-8) 2 x DECstation 3100 MIPS R2000-based 3 x DEC rainbow + much software: system kit, CP/M-86, Lotus 123, MS-DOS = Digital peripherals = various x storage expansion (BA46A and BA42B?) 6 x RX50 floppy drive 5 x TK50 tape drive + tapes Digital TU58 many x TK70 drives + tapes many x 8-inch floppy drive many x other DSSI hard drives many x RD5x hard drives - "*rare!!*" as eBay would say, and data may need wiping; - certainly available but possibly not immediately many x MMJ cables = Digital terminals (genuine) = VT520 VT320 (*) VT240 VT102 = Digital documentation = RSX-11M 1/2A-B/3A-B/4A-B/5/6/7 (ie nice and complete :-) RT-11 2/4/5 VMS: Using DECwindows (grey) VAX C (grey) some DUNIX 4.0B manuals (*1 taken) 2 x TCPware for VMS boxes = CP/M workstation = Shelton SIG/NET Gemini Galaxy 2 = IBM PC/compatible = 2 x IBM XT genuine with 386 upgrade cards 2 x IBM PS/2-70 (*) DEC Prioris w/ storageworks cabinet many x old 286-era stuff = thin client style PCs = Netvectra N30 (*) NCD ThinSTAR - WinCE 2 x mini ITX silver cases (empty...) = Apple computer and peripherals = Apple Macintosh II Apple Macintosh SE 2 x Apple IIe 2 x Apple IIgs w/ 2 x 5.25" + 2 x 3.5" ? 6 x Disk II floppy drives Appleworks GS Hong Kong Apple II clone w/ built-in FDD - another "*rare!!*" so this might be handled separately? = Commodore = Commodore Amiga B1500 ? Commodore Plus/4 several x Commodore 64 2 x Commodore VIC-20 = Acorn = 3 x BBC B 4 x Acorn electron with PSU Acorn A3000 3 x Microvitec Cub monitors = Other microcomputer = 2 x Amstrad CPC-464 Amstrad CPC-128 Atari ST 520FM Atari 1024ST 2 x Dragon-32 HX-10 - MSX Microtan 65 homebuilt Sinclair QL Tandy Color CoCo 2 = Sun = Sparcstation 1 Sparcstation 2 4 x IPX LX ...and their keyboards and other peripherals and stuff. = Other workstation = IBM RS6000 of some sort = Wyse terminals = Wyse 60 ...more to go here... = PBX systems = Tyonix with 30 handsets London 32 London 16 = Misc = Psion Organiser II printer ChannelPlus Genlock Message Centre (?) 19" rackmount fan tray 64180 in-circuit emulator Westcode systems serial port switches Intel MDS 220 lots of miscellaneous stuff for all the above - cables, ADB/Sun keyboards, etc... oodles of terminators, T-pieces Points: (1) Claim these items ideally within the next couple of weeks, although should be able to hold on to certain things for a few weeks more -- especially if you can tag something and give an approximate time to fetch it/have it delivered. (2) Unless otherwise indicated, items can be collected free from near Horsham, West Sussex, England, or will be posted absolutely anywhere, as long as you pay handling/shipping costs (Paypal etc is possible if you're abroad). If you turn up in person, you can probably take a lot more than you originally planned, if you feel like it. (3) Condition: Nothing listed is known to be broken, but everything should be considered untested. Some obvious points: Storage will be absent from the VAXen, and external PSUs missing from some of the microcomputers. Feel free to ask questions, but no guarantees! (4) Items marked (*) are probably already taken, but feel free to express your interest anyway, in case minds change. Other things may also be claimed by the time you read this. (5) Super-top-prize (of gratitude :-) to anyone who wants to provide space to store this stuff for longer (or just play with it, most importantly to SAVE it all from destruction). Feel free to e-mail me on the address below. Feel free to send this anywhere sensible. Cheers, -- Tom | tgarcia AT hivemind DOT org

Free Parts Computers in St. Louis, MO CoCo (4x 1, 3x 2, 1x 3) and Kaypro (2 & 4)

by nick＠computer-history.org

I have several parts computers available for pickup in St. Charles, MO. I have 4 CoCo 1's, 3 CoCo 2's, a CoCo 3, a Kaypro 2 and a 4. All have either cosmetic or operational difficulties, some have both. I've tried to freecycle them but had no luck. I was hoping there was someone in the area that could find a use for them. There are probably some other odds and ends to throw in as well. Nick

WD 1793 FDCs for sale

by dwight.elvey＠amd.com

Hi What I need is the improved replacement controller for the Versafloppy II. I forget the number but it was a 15?? to replace the 1771B( I think) . It was suppose to impove something about the format.
