Avail: Bull Gamma 115 (1968); IBM 3803; IBM 4361-6; IBM 3705-80 .. in Hungary

by xds_sigma7＠hotmail.com

Well if you had a 3420 and no controller, you'd be quite happy to find it... Hell I'd drive to NJ for skins for my 4381, 3880, and 3380.. MOTHERF**KING Consolidated Freight!

by xds_sigma7＠hotmail.com

Umm isn't the 3705 just a communications front-end processor? If you want a 3725, one of the yards out here in CO has one... Have a Ramtek too, and an HSC-50, both of which are rusty as hell... The 3725 has probably only been there about a year or so. Will J _________________________________________________________________ Get a speedy connection with MSN Broadband.

Railroading? Fifty year old locomotives are still in use. Automobiles? About the only recent changes are emission standards. Even electronics is not changing that fast, but if your computer is more than a year old, you are no longer"state of the art". On this basis, preserving a ten year old computer is about equivalent to restoring a 100 year old locomotive or a 75 year old car. (And cheaper too.) Cheers Charlie Fox Charles E.

Reading HP series 80 ROMs

by gil＠vauxelectronics.com

Hi folks: I am forwarding this on behalf of John Shadbolt, a buddy of mine who is not on this list -- he describes below a technique for reading HP-85 roms, for burning into eproms, which can then run from the prog-rom card. gil >From: john_shadbolt(a)talk21.com >To: gil(a)vauxelectronics.com >Date: Thu, 17 Oct 2002 09:54:03 GMT+01:00 >Subject: Reading HP series 80 ROMs > >Gil, > >Here is the procedure I used, please post this 'as is' onto cctalk, including my spam proof e-mail & web site address: > > >Reading HP Series 80 ROMs >========================= >Here are the steps. > >You need: > >HP series 80 machine with Assembler ROM or EPROM :-), a serial adapter, a PC. I have performed the following on my HP-85, I assume this will work on a 86/87/9915. > >1. Determine the ROM number for the ROM. You may have this anyway (as it is used for error messages). For example my guess for the HP 85 EMS ROM is that it is 317 octal / 207 decimal (the same as for the HP 87 EMS ROM which I do have). To check run the command: > >MEM 60000:207,2 > >This should display >317 061 > >If not then you need to try other numbers in the MEM command from 1 to 254 (eg usng a FOR / NEXT loop) until you have found all the ROMs on the system (the Assembler ROM is 40 decimal). The first two bytes of the ROM are the ROM number followed by the complement of the ROM number. > >2. Connect up a PC to the serial port and capture the output from the HP 85. > >3. CRT IS 10 - to redirect output to PC. > >4. MEM 60000:207,20000 > >This dumps 8192 bytes + text to the PC. Then send me the file on e-mail (john_shadboltREMOVETHISBIT(a)talk21.com) and I will run a conversion program to make it into binary, I can then send you the binary + Intel hex file version to blow onto a 2764 EPROM. > >5.

Selling old(er) computers in NJ

by cb＠mythtech.net

I'm having a garage sale this weekend in Northern NJ. I will be selling off most all of my 486 and earlier systems. Now I know this isn't of too much interest to people here... BUT, I will also have available the 4 IBM System 23's that I have yet to unload (not do to lack of interest, but due to lack of my ability right now to ship). As well I will probably have some other odds and ends of older machines and equipment. (ATs, and similar, dot matrix printers, a few laser printers,... I have to see what all I have). I may also have some older Macs (all 68k, most 030 or lower), I have to see what I have that I don't currently have a use for, and can bear to part with (I might have enough Mac Pluses and SEs to unload a few, if I can bring myself to doing so). I'm not expecting to get much for the PCs (if anything, really I am putting them on the lawn to see what I get before they are stripped down and thrown out), but I would like to get something for things like the IBM System 23's. There will also be some older A/V equipment, but the only stuff probably of interest here would be some 3/4" Umatic VCRs, the rest is just older amps, tape decks, and TVs, nothing fancy. And of course some of your normal garage sale fodder (I'm bringing some junk over from my house as well). If anyone is in my area and wants to stop by, let me know, I'll give you directions. Its in Ridgewood on Franklin Turnpike on the front lawn of my office (as well as some inside, we have odds and ends of office equipment to unload, and I don't feel like dragging it all outside) -chris <http://www.mythtech.net>

HP 9915 keyboard (PN 98155)

Hi Joe: Thanks for peeking in your keyboard again -- it seems you may have the only one out there. gil At 07:01 PM 10/14/02, you wrote: > I opened up my keyboard and traced out the circuits again today.

FS or FT - Bare Cromemco System Three

by SecretaryBird＠SoftHome.net

I still have that stripped down Cromemco System Three taking up space here and serving as a shin-bruising hazard in my living room, if anyone in the Pacific Northwest is interested. All it has is a pair of 8 inch floppy drives. I'm open to reasonable offers on this (not sure what would be considered reasonable, truth to tell). Cash is always good, but a trade would be nice as well. I would especially be interested in getting a Commodore PET (the type with the full keyboard instead of the chicklet keyboard, and perhaps a disk drive). The only catch is you would have to come pick it up, as I still do not have a working vehicle to deliver it myself. Any takers? -- Scarletdown

Location of Cromemco System One Revealed

by SecretaryBird＠SoftHome.net

I finally heard back from someone at my unit on the location of that Cromemco System One and Hard Drive. I was told that it went to Re-PC in Seattle (I'm assuming that they didn't mean the one in Tukwila). So hopefully, some collector in this area can find it and score it cheap. I had my shot at it earlier in the month and blew it. Live and learn, I guess. I simply didn't have enough information to go on when deciding what pieces to bring home. There should also be a System Two there as well, since there were two of them, and I only took one. Happy hunting! -- Scarletdown
