I might be interested. I am getting an Osborne Executive, but not sure whether the same Drive C would work on both the O1 and the Exec. Did you just want to get rid of it? I could pay shipping costs to me in Texas if it could work with the Exec. Reply here or to: rottman(a)juno.com my other Email address. Thanks!!

How long will they last?

You might want to take a look at the >Oric pages on http://www.ensica.fr/oric to see if any of the technology in >use there is worthwhile for your needs. I would think that all that would be needed was a standard cassette player that has both a MIC jack and a line-out jack. To make a WAV or other format recording of the data cassette, one would just plug the line out of the cassette player into the line-in on the soundcard and use your favorite recording software. You'd likely have to play with the volume to get it just right though. One would do just the opposite to create a copy of the data cassette file: plug the line-out of the soundcard up to the MIC jack on the cassette recorder. Again, it's likely one would have to play with the volume level for a bit. I used to use my home stereo system for my Timex-Sinclair's mass storage, and sometimes it got outright picky about the volume! The question then is: what sampling rate would be the best overall for this? Obviously, I don't think you'd need to use the stereo mode, but it'd be nice to keep the file size down if possible, without affecting the quality of the recording. I realize it'd be on shaky ground legally, but would any of you be interested in creating an archive of these data tape images? This would certainly ensure the programs originally provided on tape would be around much longer than the original tapes themselves.

Laser PC-4

by classicjr＠juno.com

I have had a response to my request to find a Laser PC-4 Notebook computer from someone here, but they referred me to a reseller that has modified it by adding a larger screen and more memory, which is fine, except now it doesn't have software for appointments and a clock calendar, I don't believe. They call it a Laser PC-5. Does anyone know where I could find a real PC-4 as sold several years ago? I would be interested in a used one. Respond here or at : rotation(a)juno.com

VIC-20 Programmer's Aid Cartridge

by ronaldm＠mars.ark.com

JEFF>>> At a swap meet today, I picked up 9 VIC-20 cartridges as well as one JEFF>>> program tape. Among the VIC cartridges was a 16k RAM expansion and one called JEFF>> 'Programmers Aid Cartridge' (VIC-1212). Jeff, there is a 28 page manual that comes with that cart. Following quote might help get you started: Quote: After the VIC is inserted (the cartridge) type the following: SYS 28681 (and hit the return key) The VIC will display the following message: PROGRAMMER'S AID READY All of the AID commands are now included in your VIC's internal instruction set and may be used like any BASIC commands END QUOTE The cartridge adds 20 apecial editing commands to the VIC's instruction vocabulary and gives you an easy method for re-defining the VIC's programmable function keys. the commands are: AUTO FIND OFF CHANGE HELP PROG DELETE KEY RENUMBER DUMP KILL STEP EDIT MERGE TRACE CTRL A, E, L, N, Q, U also provide additional editing functions. Function keys are assigned various jobs; ie F1 is LIST, F3 is RUN, F5 is GOTO, F7 is INPUT Of course, there is more detail as to useage and some specific examples contained in the manual. Was just trying the thing out... hoping that the HELP command would provide some syntax examples for you. Unfortunately it doesn't. The HELP command will pinpoint a syntax error in your program if you use it directly after receiving an error message. Photocopying this short manual would cost me about $5.

VIC-20 Programmer's Aid Cartridge

by jeffh＠eleventh.com

At a swap meet today, I picked up 9 VIC-20 cartridges as well as one program tape. Among the VIC cartridges was a 16k RAM expansion and one called 'Programmers Aid Cartridge' (VIC-1212). I popped the cartridge into the VIC-20 and the computer still boots right into Basic 2.0. Is this some kind of debugging cartridge then that helps with errors and such? None of the cartridges I picked up came with the docs but the ones I've tried seem to work ok so far. Also, can anyone explain the reasoning behind the different color schemes for the labels? The Gorf and Radar Ratrace cartridges I already had both have cream cases with cream/brown/black labels. The new cartridges I got today have brown cases with silver/black labels, though some have off-white cases with silver/black lables, while one has and off-white case with a silver/gold label! All of these are from Commodore.

Computer Listing

by MTapley＠swri.edu

Brett, I couldn't help myself (and besides, I won't have web-acess this weekend) and looked already. This is gonna be way, way, way cool. I have some minor questions/suggestions. 1) Check those features/dates/etc I posted for the Rainbow with somebody who actually knows. I have not done so, and they were just from my often-flaky memory. Some real Rainbow expert should please chime in here and set me straight on whatever I missed. 2) There actually does exist a Rainbow web site. Under construction at the moment, its url is: http://b61984.student.cwru.edu/rainbow.htm Can users just enter a link like that instead of a link to an image? Or can you add a field for that kind of link? 3) How does info get edited? Is it locked once entered (to prevent net.vandalism or well-intentioned but incorrect "corrections")? Maybe each computer web page can be changed only by emailing you, and is put under the responsibility of a single volunteer to make sure what's there is correct? Or maybe just put in an edit facility so anybody who so desires can add info? In any case, *thanks* for setting this up. I am really looking forward to browsing this site. - Mark

Intel MDS (Microcomputer Development System)

by dmabry＠mich.com

Hello all, Just wanted to ask if anyone out there has an Intel MDS (Microcomputer Development System). That was the 8080-based system that Intel sold for developers to develop hardware and software based on their microcomptuers. It ran an operating system called ISIS-II from Intel. An interesting point of trivia is that Gary Kildall originally developed CP/M on the first 8080-based MDS called an Intellec 800. This system was based on the Multibus (a bus system developed by Intel and used in lots of industrical applications of single board comptuers). If you happen to buy a CP/M in the generic form it would run on one of those Intelled 800. Anyway, anyone who would like to discuss these systems, I'm game. I have an Intellec 800 and a Series II (the successor). I would be interested in anyone who might have for sale a set of floppy diskette controller boards for these systems. It is a two-board set and I need the double density version. Thanks. -- Dave Mabry dmabry(a)mich.com Great Lakes Maritime Institute Underwater Research Team NACD NSS-CDS #42872

Help with Osborne 1 and TI 99/4A needed please

by george.lin＠documentum.com

Hi all, I picked up a very nice Osborne 1 from a local thrift store yesterday. The system powers up. Everything looks good. However, I don't have the boot disk. I tried the CP/M boot disk from my Kaypro II. No good. If I remember correctly, the disk drives on old CP/M machines are not compatible with each other even though the binaries are. It looks like that I need an Osborne formatted CP/M boot disk. Does anyone know where I can get one? Also, it would be nice to get a CP/M communication software on an Osborne formatted disk so that I can start transferring other CP/M software to it. In the same store, I picked up a Peripheral Expansion Box for my TI 99/4A. It comes with 1 floppy disk drive, 32K memory expansion, serial adapter, and flex cable adapter. However, the fuse and the cap that holds the fuse in place are gone. Does anyone know the specification for the fuse or know where I can get a replacement for it and the cap? Any help is greatly appreciated. George -- George Lin "Accelerating your business through Network Architect, MIS enterprise document managment." Documentum, Inc.

Insurance of your collection...

by kevan＠motiv.co.uk

Ok, what do people do about insurance of their computer collections. I guess mine is covered on the plain old house contents insurance, but the more I think about it the more I worry about a potential claim for over 60 old (and I guess in the minds of insurers, obsolete) computers. I guess insurers will want a current market value, but what is current market value for old computers? As far as I am concerned there isn't a market value and each computer is only worth as much as the person selling it wants for it, or what the purchaser is willing to pay. I have recorded the prices I have payed for most of the things I have in my collection, but some of the rarest and most valuable to me I got given for free. Other items I have payed a lot of money for, probably too much sometimes when I realy want the item. In no case have I got a reciept for a purchase. Thoughts please. -- Kevan Old Computer Collector: <URL:http://staff.motiv.co.uk/~kevan/>

Osborne Accessories?

by classicjr＠juno.com

I'm about to become the proud owner of my first Osborne Computer. An "Executive" is being sent to me next week. I can't wait to get it going. I have on old catalog from the "JMM Computer Products" from Auburn Washington which details many accessories and cables that they sold for the Osbornes. I may be interested in getting a Parallel Cable, maybe an internal Ram Disk known as "Drive C" or maybe a Bios upgrade, or some software. Anyone have a source for these items now? Such as the Ram Disk or maybe a Hard Disk upgrade?? BTW, I have color brochures of all three of the Osborne machines, the O1, Exec. and the Vixen that I have stashed away since the 80's. They are fun to look at once and a while.

C Itoh Video Terminal

by idavis＠comland.com

I have a C Itoh Video Terminal model number CT101. If anyone can use it, and doesn't mind paying shipping, I would be happy to send it to them. It is in good working condition, there are some crayon marks on the side, but I'm sure they will come off. I put it into my kids room and let them hit the keys and watch the characters come up on the screen. They thought it was the neatest thing. It is nothing more than a dumb terminal, but I know some of you have mini computers and might be able to use it as a console or something like that. Just email me and let me know, or if you need more information. I live in Austin, TX. and would bring it to work if you are local and don't mind picking it up. It's nothing really special, but I hate to throw out something that someone might be able to use. Isaac Davis idavis(a)comland.com indavis(a)juno.com

Epic Computer

by bm_pete＠ix.netcom.com

Greetings; I've found/uncovered another computer in my garage, does anyone know anything about it? The label says Epic Computer Products, Inc. Fountain Valley, Calif. Model 2296 It measures about 9" wide, 7" high, and 14" deep (breadbox size) Most of the space is taken by 2 FH 5?" drives (Qume model 592) one drive has a disk in it which is labeled 77 tracks/side, so I assume they are 640K or 720K. The processor is a Z80A with 64KB, so my best guess is that it's a CP/M system. The back panel contains a RESET button, a TEST/NORMAL switch, a DB-25F connector with a switch labeled toCOMM EQUIP/toPRINTER, a Centronics connector labeled PARALLEL, and a couple of other "phone jack" type connectors. (I don't know the name for these connectors, but they're the same size as the one on my phone-handset connection, not the plug-in-the-wall size) One of these connectors is labeled CONSOLE, the other is labeled PRINTER SERIAL. I would like to get this thing running, but don't know how to do it, what to use, or where to connect it. Any help/info would be appreciated. _______________ Barry Peterson bm_pete(a)ix.netcom.com Husband to Diane, Father to Doug, Grandfather to Zoe now and to Tegan soon!

Anyone on the list ever heard of the Laser PC-3 and PC-4 Laptop computers? They were small NonDos, NonWindows computers to be used mainly as Organizers and Word Processors. They were out about 7 years ago and sold at Sears stores, etc. I sure would like to get one of those machines... Especially the PC-4, with the bigger screen. They came with a choice of Ms-Dos or Mac connection cables and Software. Anyone know where I could find a PC-4 ??

I picked up a second Aquarius the other day, this one from Mattel, while my first doesn't bear the Mattel name anywhere on it, and seems to have been sold directly by Radofin Electronics. Other than the Mattel name missing from the case and ID label though, and the fact that the Radofin machine has an 'R' tacked to the end of the model number, they are identical. The third variant I've heard of, but not seen, is the PAL version sold in the UK. I don't recall it's model number, but it's model was totally different than the 5931 model of the US NTSC version.

The return of the 'Mark-8'

by jimw＠agora.rdrop.com

(Attempting not to drop into 'blatant advertising' mode... B^} ) In preparation for an exhibit of 'Classic Computers' that I am working on with other local collectors and the Oregon Museum of Science and History (OMSI - http://www.omsi.edu) to be presented this November, we are planning to reconstruct (at least one) functioning 'Mark-8' microcomputer as originally presented in a construction article in the July 1974 edition of 'Radio-Electronics' magazine. (predating the presentation of the 'Altair' construction project in a competing magazine by six months) Briefly for those not familiar with the unit, the 'Mark-8' (referred to as a "minicomputer" in the original article) is an Intel 8008 microprocessor based unit with a clock speed of 500kHz and a maximum addresing range of 16kb. The unit as implemented in this project features a full 'programmers' front panel, and is constructed on six double sided circuit boards which comprise the CPU board, parallel data input and output boards, display board, address latch and memory boards. The reconstruction as I will be implementing it will add a seventh board to stand in for the original memory board which was designed for 1101 static RAM chips which are no longer available in any quantity. The revised memory board will substitute 2102 static RAM chips which are readily available. (Note: there is a possibility that we may just update the existing memory board layout to allow the use of either RAM chip, but we are not quite that far along as yet) To help defer the costs of having the circuit boards made, we are offering sets of the boards to interested parties at our cost. Currently, with the minimum run of boards to make this project practical (6 sets) the cost per set stands at $200.00US. Four sets are currently spoken for. To get this rolling, we at least to find people interested in the other two board sets, and if more people are interested we can get the price per set down even further. (or if someone out there works for a PC board house???) And, since someone will no doubt ask... Yes, we do have a source for the Intel 8008 microprocessors. The quantities are limited however, and the current price for the microprocessor is $200.00US. All other required parts to construct this unit are readily available through stardard sources. Also, through the kindness of the management of Gernsback Publications (publisher of 'Radio-Electronics' and other related publications) we can provide reprints of the original construction article and documentation set for the 'Mark-8' project to anyone who purchases one of the board sets. (with updates for the revised memory board) If anyone is interested in joining us on this classic adventure or has any questions, please feel free to contact me.

On Fri, 21 Mar 1997 17:54:15 -0500, "Captain Napalm" uttered: > but you might want to add an availability field [for (in the good Captain's case, microcomputers)], something like: > Limited - only a single run ever made, and then, not very > many. How about some of the rarer minicomputers that were made in the '60s? Beasts like the LINC-8 (of which there were only 142 built) or Packard Bell equipment from the very early sixties count here. PDP-1. > Rare - Only made for a year or so. I'd put into this category the Classic DEC PDP-8, and orginal Data General Novas. PDP-12s might go here (production run of ~1000). > Uncommon - the less popular machines of an era. I'm speculating at this point, but I'd tend to lump Prime equipment and Interdata gear in this one. You can find them, but it's a lucky find. Later Novas and Eclipses might fit here. > Common - Fairly easy to find. DEC pdp11 gear fits, for the most part here, although a case can be made for the 11/20 to fall into the "uncommon" classification. This class is especially appropriate for early- to mid- life 11s. > Abundant - the era of the PClone. Can't go to a thrift > store, auction, ham fest, etc without finding > hundreds if not thousands of old units. This is a level of concentration that you'll never find with mini- computers. In this class, I'd tend to place late-life-cycle pdp11s, like the 11/84 and up, and various classes of small VAXen. Note that in many cases these machines are still performing their assigned tasks and may not be de-commissioned for several years to come. I hate to flog a horse that's weak, but there is more to computing life than microprocessors. Whilst I don't disagree that the micro- based machines should be preserved (they should), I hope that folks, through their study of machines' history, become aware of what is now _distant_ history, even though it only happened 25-35 years ago. Bitmapped displays and typewriter keyboards are nice, but it's also good to sit in front of the blinking lights and work switches to program the machine. ______________________________________________________________________ | | | | Carl Richard Friend (UNIX Sysadmin) | West Boylston | | Minicomputer Collector / Enthusiast | Massachusetts, USA | | mailto:carl.friend@stoneweb.com | | | http://www.ultranet.com/~engelbrt/carl/museum | ICBM: N42:22 W71:47 | |________________________________________________|_____________________|
