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.

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)? cje -- Chris Elmquist
