As promised - here's the list of all *loose* S100 boards we got. There are more inside the Northstars and the Minstrel S100 machines of course, so more yet to come :-) (We've looked inside the Northstars though and there's nothing *that* fancy inside - some are empty, others have just typical CPU / RAM / Floppy boards inside. One has a floating-point board from memory) CPU ----- 4 x Cromenco ZPU Ithaca IA1010 Z80 CPU Board NorthStar ZPB Z80 CPU Board HiTech SPAM Z80 CPU Board Morrow MPZ80 Z80 CPU Board JC Systems MCM80 Z80 CPU Board Polymorphic CPU 8080 CPU Video ------- Microdiversions Inc.
