I've finally purchased a digital camera! Any recommendations on photographing machines? resolution, size, positions - front, back, inside, screen shots? I was thinking of starting with the machines I'm currently working on (cromemco system 3, AS400 9404, and Commodore SP9000) and then move through the collection as time and web space permit.

Phonemark "Quick Data Drive" - info?, also WTD Commodore 15xx drive, info.

by Joel.E.Bradley＠syntegra.com

Ahhh....I have one of those c64's, original monitor, drive, tape, etc. I also have the "Mach 5" fastloader cartridge..I often wondered if it was just full of RAM? I did like the shortcuts that were built in which saves on typing. I wonder..does anyone out there have a copy of the game "Airborne Ranger"? It was a superbly done game, and I remember how to play, but I have lost the manual. One problem is that the copy protection feature built-in was that you had to look up a medal ribbon that was located in the manual. Without that, it wouldn't let you play!

I think QOS was loaded at the same speed as a normal cassette load, and that QOS was similar in concept to the cassette 'turbo loaders' that were popular with the C64. -tony

First, strip and tin the wires, and trim to length (short). Stick the miniDIN in the potato, re-tin the pins if it looks like solder might not stick to them instantly. Apply the wires, one at a time, with just a touch of the soldering iron, using the solder already on the pins and wires to make the joint. The potato makes a good heatsink. If you don't have a potato, try a crisp apple, or a miniDIN socket (which will at least prevent the pins becoming seriously mis-aligned). > 4) Where's my coffee?

DEC PDP-8 Paper Tapes?

by rigdonj＠cfl.rr.com

I picked up a bunch of unknown paper tapes last week. I was sorting through them today and found several tapes that have "Digital Equipment Corporation Programmed Data Processor" printer along the length of them. The label on one of them also says "Memory CKR BRD (LOW)", "Memory CKR BRD (HIGH)", "Memory ADDR BRD (LOW)", "Memory ADDR BRD (HIGH)". That one also has "PDP-8" written on it in pencil. So I'm guessing that these are all for the PDP-8. The tapes are marked variously "DB3", "DB4 SIMAT #1 3 SW TEST", "PAL III", "Combined BB#51, INT #15, CORR #21 and Patches 1-11". Does anyone know what these titles mean? All of the tapes are on blue plastic spools that are 4 inches in diameter and 1 1/4 inch thick. Each spool has a removable blue plastic cylinder (with one end closed) that slips over it. In the center of the spools are white plastic inserts with a hole and three radial drive slots. The covers are marked "Reel-Dex Part No. 30" and "Numeridex Incorporated Wheeling, Illinois 60090". It's pretty obvious that the spools are made to be used directly in a PT reader. But does anyone know what kind? Joe

Integrated Computer Systems Standard Prototype Microcomputer

by classiccmp＠vintage-computer.com

<< This is a re-sent message - slightly updated. The first two are probably queued and should be deleted. I'm sorry in advance if I end up with multiple posts >> Hello, I've just come into possession of an "Integrated Computer Systems Standard Prototype Microcomputer." The system, as I received it, consists of three parts: a power supply, a single board computer/trainer similar to a Kim-1 and an "interfacing" board. The "computer" part has an 8080a (AMD), 4 2708 EPROMS (one labeled MDS DEMO) and a bit of RAM (2114s) as well as a hex keypad surrounded by control keys (reset, step, run, etc.) There is an eight position LED display above the keypad. Sections of the board are labeled with their functions including clock, control logic, buffers and address decode as well as keyboard and display and tape i/o. There are two 50 pin connectors tagged as ITS and S-100 and two RCA plugs for, I assume, audio data in and out. I guessed that the ITS connector should connect to the "Interface System" mentioned above. The "Interface System" has a bunch of different connectors around the edges including ones labeled for Serial, TTY and RS232 interfacing. There is also a "thermistor experimental board that includes a cooling fan with opto-speed control and alarm circuitry" that will be coming under separate cover. For the price I paid I wasn't expecting this to work on arrival so I wasn't surprised to find that it's flakey at best. When powered up the LED display is random and pressing the reset button will usually clear it, but not without random stuff popping up from time to time. No other keypad keys seem to do anything. I've put pictures up at http://www.vintage-computer.com/ics.htm (sorry that they're a little bigger then usual) Has anyone ever seen one of these before? Does anyone have any manuals for it or any ideas what might be wrong with it from my brief description? Google turned up nothing. . . Thanks! Erik S. Klein www.vintage-computer.com

CDC Cyber mainframe emulation

FYI. See below... ---------- Forwarded message ---------- Date: Sun, 12 Jan 2003 14:04:24 +0800 From: Tom Hunter <tom-hunter(a)bigpond.com> To: vcf(a)vintage.org, archive(a)vintage.org Cc: cgd(a)theworld.com Subject: CDC Cyber mainframe emulation Hi, I have written a free emulator for a CDC Cyber mainframe and a set of typical peripherals. The software is written in plain C and currently runs on Win98/NT and various UNIX platforms. I have released both source and binary. If you think this is of interest, please visit my web site where you can download a ZIP archive of the sources, a Win32 binary and the Chippewa OS (handcoded in octal by Seymour Cray). My web site is: http://www.users.bigpond.com/tom-hunter If you have any CDC Cyber related software tapes, could you please send me a list of what you have. Top on my wanted list would be SMM sources matching and binaries. SMM is a system diagnostic which would help finding any remaining problems in the emulation.

DOS 3.20

by Edward.Tillman＠valero.com

I'm looking for the MS-DOS version, (preferably with the disks intact, but not essential...). It was paperback, nearly 2" thick, had a two-tone cover (white over gray), and was somewhere over 300 pages in length. It had all the instructions in the world for using a DOS system - from setting up the autoexec/config, to working in the AT console (e.g.: modem command strings), to all the various switches for all the internal and external DOS commands, to programming in GWBasic. I really miss my book (I lost it in a house fire a week before 9/11...) That info is nearly murder to come by now days, and yet there are still legacy systems out there in everyday business use. That's one of the reasons I want the book. The other is that I want to setup a current day system (AMD 1.6Ghz or higher) as a straight DOS machine for experimentation, games and taking others back through history. DOS 6.22 would actually work, but I really liked the older DOS better, and the "newer" versions' texts weren't quite so insightful.

DOS 3.20

IBM PC-DOS or Micro$oft MS-DOS?
