What's the rarest or most unusual computer-related item do you own?

[dwight]

You reminded me of two other interesting things:


One is an early development system for the I4004.

Includes a SIM4-01, MB-410 and MP7-03.

I've actually written some code for it. Blowing 1702As by

the serial 110 baud is about 7 minutes. I wrote code to do

a standalone copy of another EPROM that runs in 2 minutes.

That of course is I4004 code.


 I also have a NC4000 Forth computer that I've connected

a 5Meg had drive to and two 360K floppy drives. I used parts

from old XT computers, found at surplus shops. I am able

to recompile the entire Forth operating system in less than

15 seconds with the old MFM hard drive as source.

ETA-10 CPU board?

The star off the front of one of those STAR machines

Two mag tapes from Univac I.  They are 8" dia, steel and weigh about 8 lbs each ;-)

IBM 5100?

Two i4040 engineering samples (that work)?
