Osborne OCC1

by CochraneS＠sgstool.com

I have come across an Osborne model OCC1 Serial # 134033. This unit has the 300 baud modem. It also has 5 1/4 disk with it. (SuperCalc, WordStar, Qbasic) The unit boots up and runs the software but after about 15 to 20 minutes it starts to overheat.(smoke) My question is - What is the selling price for a unit like this and where would be the best place to sell it?

Selling it off. What would you keep ?

by lgwalker＠mts.net

I am at a point where I am thinking about divesting myself of the majority of my computer collection. Partly needed bucks driven, partly tiring of it all. A small museum is unlikely and I have other unfulfilled interests which I might focus on as an old fart. Likely on E-Pay because we're a notoriously cheap (or poor) lot. What would the list retain if they were cutting down or getting rid of the majority of thier collection and keeping enough to keep thier hand in. The game machines are easy and the first to go. I would think of retaining an IBM PC and another good DOS box. A CP/M machine. Maybe a Rainbow and let the Kaypros, Osborne, and others go. A hip old laptop, In my case a Grid 1520 and my Sharp handheld. Maybe one old early box like my Micom, H-89. or TRS m.II An Atari 8-bit and / or CoCo 3 An ST and Amiga 3K An IBM PS/2 likely the 8590, altho who would want 8580s, a more significant machine. Maybe one kept by default. And a newer DOS box and laptop. And then looking at this exclusive list it won't be easy. Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

More dumb VAX 11/750 questions

by alanp＠snowmoose.com

Hi guys, Finding this list has encouraged me to try and get some stuff together on my VAX. Sorry for the extra traffic. Q1. Right now I have a UNIBUS expansion cabinet attached to the primary 11/750 cabinet. I would like to replace it with my TU80 (with a RA82 in the lower drive bay). Can I just move the UNIBUS cards that I want to keep to the primary UNIBUS and pull the DW750 from the CPU back plane and be good? The James Lothian FAQ mentions something about reconfiguring some jumpers if you install a DW750, so I would probably need to change them back if I remove it, right? Q2. Right now I have a DEUNA, UDA50/UDA52 and DHU11 in the primary UNIBUS with those bus continuity cards installed in the open bus slots. On the secondary UNIBUS, I have the TU80 controller, another DHU11 and a DMF32. Can I just pull the bus continuity cards from the primary UNIBUS and install the TU80 controller and DMF32 in those slots? Q3. Right now the memory slots have M8750s CJs in both end slots and 6 six National Semiconductor 753 1M boards in between. Does it have to be this way? I have two spare M8750s. Are there any advantages between the DEC memory boards and the NS boards? Q4. I have a floating point option board (L0001) that is supposedly intermittently bad. Anyone know what kinds of things fail on these boards? Q5. Should I use or not use some kind of contact cleaner on the board fingers and the sockets they go in? Thanks, alan

MicroVAX II

by Antonio.Carlini＠riverstonenet.com

>only the power harness. And assuming one couldn't find a replacement power harness for the bad >one, what would it take to modify/repair the bad one to make it safe to use? Is it just the matter >of replacing some of the existing wire with something of a heavier gauge? I believe the problem is that the wires are of differing lengths and hence resistance. Plus they were (or may have been) specced a tad to near the limit. The end result was that the longest wire (greatest resistance) heated up the most and eventually went phut, leaving the other five (or so) to go pop shortly thereafter. So heavier gauge and same length would seem to be required. OTOH if the problem was that bad (none of mine in the lab ever exhibited any pyrotechnic tendencies) would it not have corrected itself by now :-) Antonio

Modern replica/implementation of a dumb terminal?

by Robert_Feldman＠jdedwards.com

I have heard of people using an HP LX palmtop (the 100LX/200LX have a fuller serial port implementation than does the 95LX) as a terminal for the type of tasks you mention. The 200LX runs MS-DOS 5.0 on an i80186, so you should be able to get a number of terminal emulation programs that will work on it. -----Original Message----- From: Ethan Dicks [mailto:erd_6502@yahoo.com] Sent: Tuesday, November 26, 2002 1:10 PM To: cctalk(a)classiccmp.org Subject: Modern replica/implementation of a dumb terminal? I was musing about the state of VT100s and other dumb terminals and had a few ideas zing by... <snip> I have used my Palm Pilot as a portable terminal for reconfiguring Cisco routers (VT100 app and a travel cable and the appropriate RS-232 dongles). My boss at the time flipped when he saw me do it (everybody else dragged a laptop into the server room). There are just times when I'd like a laptop-sized-or-smaller ANSI terminal. I can forego double-high/double-wide chars, inverse video and the like for simplicity's sake (hardly ever used them in an app except at the South Pole), but it should be complex enough to run a screen editor (vi or emacs) and/or basic curses apps (Rogue/Larn/NetHack and the like). One place I thought BIOS replacement might be handy was in a sub-486 laptop.... just pull it out, plug it in and *voila*, it's a dumb terminal weighing a few lbs. Yes, it's possible to drop an OS on a floppy and add Kermit (I've already done that with a dual-720K- floppy Zenith 8088 portabie). I'm thinking of a dedicated "instant- on" experience. I also have some "Net Stations" with a 5"x5" 486 motherboard stuffed under a PC keyboard (with 4 30-pin SIMM sockets, IDE, serial, video, and NE2000 network built-in). They don't run off batteries, but neither do they have an intergral screen. I've also tried to think of ways to adapt a Palm Pilot with a permanent keyboard, but I'm not sure there's a way to do it with only one serial port (terminals typically have at least two, even if one is dedicated to servicing the keyboard and somewhat "invisible" to normal operation. The final angle I've worked on is to recycle the main board in a VT220 (being somewhat physically small), but I don't have schematics and I don't know what signals go over the ribbon cable to the PSU/ Analog board under the CRT. So has anyone else wrestled with how to cobble up a portable VT-100? Anyone get any further? -ethan __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.

Superb Exidy System on Ebay in Holland

OK, both have Z80A processors, > both used 2114 RAMs. But [ snippage ] I didn't realise they were so different inside. I knew the Ace didn't use the ULA but I thought the basic architecture was similar to the ZX80/ZX81 (apart from the screen memory, which I knew about). There was certainly a rumour at the time that that was the case, but I dare say that was as much due to the similar size and shape of case as anything else :-) Perhaps "inspired by" is better than "based on". I have the manuals for ZX80, ZX81, and the Jupiter ACE, and the service manual for the ZX81, but the only one of those machines I possess is the common-or-garden ZX81. Twice I've just missed getting a ZX80, and I've seen a few, but I've only seen seen one ACE. -- Pete Peter Turnbull Network Manager University of York

OT - Thinkpad 760CD

by healyzh＠aracnet.com

I've got a IBM 760CD Thinkpad that I want to try and replace the HD with a larger one that I have on hand. After looking over the laptop carefully, and trying to find info on the IBM website I'm left with one important question. How on earth do I replace a HD on this model? Zane -- | Zane H.

Old computers

by gfrajkor＠ccs.carleton.ca

Does anyone have an address and some contacts at the computer museum that NASA's Ames Research centre in California is putting together? There was an article about it in the New Scientist Magazine. Here's the reason: some time ago a museum allegedly building in Colorado approached me about taking away some old machines I have... I promised them, but nothing every came of it and the storage bills are killing me now that I am retired. I will give them away, but I do want to do it on a wholesale basis rather than piece by piece. Here's what I have: Dec PDP 11/34, two RK06 drives (was working when retired). Drives are, of course, the big washing machine ones. 11/34 is in an "executive" rack. Dec PDP ll/23, two RL02 drives, in usual tall rack. Broken pin in ribbon cable to the mini-drives used for booting and diagnosis. RL02s were working when retired. Lots of manuals and some spare platters for the drives. Quick and Timely (Seattle company) CP/M box, S100 bus. Working when last used. Matrox (Montreal company) CP/M box, with old analog-digital conversion attachment, used for scientific experiment data gathering when retired. No documentation, but some boot floppies for the above. Commodore 8296. Beautiful looks. Last Commodore entry into the 8-bit business computer field. With dual floppy drive. Some software. A few miscellaneous Atari STs. monitors, floppy drives. Since I am in Ottawa, California might be a long way to transport the stuff but since some of it seems rare now and the Ames Research centre seems intent on collecting stuff, they might be willing to pay for a truck >from here. I would appreciate advice. ahoj -- ------ Jan George Frajkor _!_ 221 Arlington Ave. --!-- Ottawa, Ontario | Canada K1R 5S8 /^\ aa003(a)ncf.ca /^\ /^\ gfrajkor(a)ccs.carleton.ca h: 613 563-4534 fax: 613 520-6690

Microprofessr MPF-1 Manuals?

by glenslick＠hotmail.com

The -IP model has a full qwerty keyboard and 20 character alphanumeric 14-segment display instead of just a keypad and 7-segment LED displays so I assume the monitor code would be significantly different. >From: "John R.
