Someone contacted VCF looking for information on an early intellec 4 mod 40, a copy of the original RAM based native assembler

Dave McGuire LSSM received an Intellec 4, a 4 Mod 40, and an 8 Mod 80 this past fall. Included with the systems was a large amount of documentation and, I believe, software on paper tape

I'm working with Jeff's person. They provided me a ROM image of one of their boards, which contains the same 4040 ROM monitor code as my intellec 4/40 and Kyle Owen's intellec. https://www.retrotechnology.com/restore/int_440.html https://www.retrotechnology.com/restore/intel440_roms.html There's some intellec 4 40 resources around the Web but not too many. So any code or ROMS found on these systems should be evaluated and shared if at all possible. Early-EARLY-days microcomputer systems like these are unique computers by any standards; because there were *no standards* in those days. This is a hard fact to appreciate in a world of consumer computers. Example: The 4/40 never used any mass storage other than paper tape. The 8/80 didn't have Intel-supplied floppy drives; by the time of floppies Intel moved to the Multibus (these aren't Multibus). So, any code would be either paper-tape, or printed source listings, or something archived later onto floppies. Regards Herb -- Herbert R.
