 |
|
I wondered which kind of electronic components should be worth to collect besides CPUs (and Memory or EPROMs) from a CPU collectors perspective.
I started with flat packs while I read about the AGC (Apollo Guidance Computer) and its development. When I visited Genna in 2004 I was at the Smithsonians museum for space and air and saw a nice little board from the Minuteman I project. These small white ceramic pieces with coloured lines were really fascinating to me. Unfortunately I didn't see one for sale anywhere until now.
And I think to get a small Pre-CPU exhibition it is nice to have just some tubes (where the first ones seem to be DeForest Audion. I got some later examples recently on ebay, btw, pretty cheap). Then a few examples of early transistors and canned circuits.
Here's a nice site with informative stuff:
http://ourworld.compuserve.com/homepages/Andrew_Wylie/homepage.htm
Also core memory is part of a complete history.
Or program boards done by wired cables (which I've seen too at the Smithsonians from Saturn V) but I guess I'll never find one:-(
... and you? |

How about old mainframe boards and equipment:
Or early digital displays:
Or even analog computer stuff:

I collect chips from the Pixel Plane and Pixel Flow projects that were developed at the University of North Carolina in Chapel Hill.

Not sure what you mean worth to collect ..
I dont collect for financial reward, I collect because I enjoy it - clearly there is a value to my collections but that is purely secondary at the moment. For me I only started collecting cpus as I had so many by the late 1990's ( used to upgrade cpu/mobo/etc every 6 months or so), and I remember wanting a 486 so bad in the early 1990's. So thats why I like the intel 486 
Other than limited range of CPUs I collect, I also like to get Microchip PIC's, usually only the JW type ( with quartz window). I have always liked them ever since I started to use them at work from around 1997 onwards.
Now its all Flash memory and the PIC's are so fast.
Electronic displays make good collecting - even better if you can invest the time to get them going again. I have a bunch of different types, and it helps to be able to program microcontrollers and to make driver boards to get the displays working easily. chip68 has posted a couple nice ones there, pretty rare. |

When I was about 12 years old (40 years ago!), my best friend and I collected small electric motors. I still collect them on a limited basis.
We also fixed old radios and TVs. All the TVs then had tubes and we would visit the local drug store tube testing machine to check boxes full of tubes. The good ones were used to repair the TVs/radios. I still look for old tubes and have a tube tester made in the late 60's.
My fasination changed to computers in the late 70's and I have worked in that field ever since.
Many of the CPUs I have collected came from PCs I worked on 20 years ago. Wish I had saved more of them.
A friend worked for Spectrum ceramics where they made the ceramic parts for the chips. They went out of business when chips started being made of plastic and fiberglass.

I remember that too. It might have been at a hardware store though. |

You guys must be old!
Let's start up a chip-testing service in store! |

I think that CPU and RAM, HDD and others hardware is one big and wide lectronic family for collectors.
So, I have a passion for Seiko Vintage watches too.
