Like many collectors, I don't just collect computer systems. I also collect other interesting items related to computers. For me, items that have something to do with the evolution of computing or that have to do with documenting personal computing are the most compelling. I also collect parts of machines that I own or may someday own so that I can keep my collection running.

Lear Siegler ADM 3A dumb terminal

The Lear Siegler ADM 3A was a very common dumb terminal in the late 70s and early 80s. They were frequently used to connect to Altair, IMSAI and other similar systems.


I have a copy of VisiCalc for the Apple ][ in my collection. This program is historically significant since it was one of the first unique and useful applications available on microcomputers. It was so useful, in fact, that many corporate types purchased Apple systems just to run VisiCalc and often had to sneak them into work since the "big iron" IS folks weren't yet sold on the idea of microcomputers.

Apple ][+ bare motherboard Apple Chips

If I ever need to repair my Apple ][ Plus I have both a spare, bare motherboard and a full set of chips with instructions.

Core Memory

Just for fun I have two cans of Ferrite Cores. These little donut shaped beads were strung on a matrix of wire to the make "core memory" used in many older computers such as the DEC PDP/8 and the IBM System 360.

The S-100 Bus Handbook

The S-100 Bus Handbook by David Bursky is one of the best S-100 resources out there. As such, it is still a very sought after item.

Televideo 925 Mantenance Manual

With a Televideo 925/950 terminal in the collection it only made sense to get a copy of the Maintenance Manual.

Teletype model 43 ribbons may be extinct. I have some but they won't run anymore. The ribbon is fairly short and a continuous loop that depends on an ink filled foam roller for reinking. That roller has disintegrated in all my ribbons. I suspect my 43s may go to goodwill next week.

300 baud serial 8 bit. I'll keep the manuals and tools.

I have some Color Computers sitting around. Don't even know how many! 1's, 2's, maybe 3's. Setup with three floppy drives for a single computer, and lots of software. Books, magazines.

I have two Timex-Sinclairs: the 2068 color computer with 48K of RAM and a stringy floppy drive, plus an original Timex-Sinclair 2000 with 2K of RAM, a 16K external module, and a full-size keyboard wired to the original box. All worked last time I started them up, but that was about 5 years ago. I also have much of the original software, including VuCalc. Loved that computer for its outstanding instant error checking BASIC, but hated not having a floppy drive (hard drive? What's that?).

I own a computer repair center in Daytona Beach, FL. We have been in business for 13 years - and needless to say, we have amassed a huge collection of parts and systems that to most people have no value. Can you send me your email address and as I go through the items, if I see anything that I think might interest you, I will send you the information. The items will be at no cost 99.9% of the time. THanks.

I cant for the life of me find a manual either electronic or printed, for MC6801 CPU!

Can you help?

Thanks Sam

(Submitted March 3, 2005 17:10:12 by Art Mendez)

I have a tiny Philips NMS 6201 terminal (apparently, the labels are worn out by aging) . It looks like a Minitel terminal.

The little fellow has a small B&W CRT monitor, a keyboard that nicely pushes and locks into the plastic cabinet, a built-in modem with line/phone port combo, and a round 5 pin female port.

It was used in the late 80's in Mexico, as the first intentions of bringing electronic banking to special customers. I just brought it out the gadget den, as I am building a computer museum (mostly working) for youngsters (I work for an education institution).

I just can't find documentation on it. Anyone happens to know something or any source?

It must have some kind of EEPROM inside. I would like to set it off to do something for demo purposes.
