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

At 12:48 PM 3/28/97 -0800, you wrote: >Hi! > >If you still have this, I would definitely have a use for it... I have about >7 Unix machines that I could use an extra dumb terminal on... > Jay Vaughan Jay, It's yours. I will try and box it up this weekend and ship it out early next week, it's not extremely heavy, but it's close. I will even see if I can get the crayon off of it. There's not much, just a little scribble, but everything works just fine on it. I don't have any cables to hook it up, just the keyboard and the monitor, but it looks like it has standard rs232 and parallel ports on the back. I knew someone could use it, and sure hated to throw it away. I have never really shipped anything(man i'm naieve), so if you want anything special fed-ex wise, email me and let me know what to do.

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!
