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.

Two i4040 engineering samples (that work)?

Hi Everyone!
I thought this would be an interesting question to ask around -
What's the rarest or most unusual computer-related item do you own?
For me, personally, I have a Altair 8800!
Looking forward to hearing your answers
That's a tough one. A 1401 core plane? Some CDC 6000 "cordwood"
modules? Two Durango F85s, complete with 14" Shugart hard drive?
Got a couple of boards that I don't even know the provenance of.
PSU diodes and heatsink from a STAR 1B?
Lotsa junk.
