Ahhh, the RML 380Z, I went to the local college in 1980 and they had one for students doing computer science courses, a big rack mount style case with two 5 1/4 floppy drives (single sided?), 56 K RAM, colour graphics and a keyboard built to survive World War III, the keyboard supplied with the original IBM PC has a reputation for being indestructible but it’s nothing compared to the one that came with the 380Z.
