Default Orton NIBL computer (closure after 40 years!)

Hi All,

Firstly, I have to say how heart-warming it is for me to see my old friend - the SC/MP microprocessor - getting so much attention recently in the Vintage Computer section. Programming the Z80 is so much easier, but I'll never forget the revelation I had when I grasped the ins and outs of the simpler SC/MP. "I can program this!!!!"

In many ways, this is the computer I wanted to build circa 1978, but for all the usual reasons it never happened (cost being a major obstacle). I wanted a NIBL machine, plus a set of utilities (which I call 'Page 2 support') to handle cassette I/O, usual 'monitor' style commands to examine memory, support for a printer, and most importantly, an assembler to augment NIBL.

Although I've used modern parts, this machine could be built with real vintage parts, and I'm certain it would work!

Anyway, enjoy!
