Sinclair jump started programming in Europe
Oh man, the memories! :) I started with the ZX-81 but quickly moved on to the Spectrum:
LD HL,16384
LD D,H
LD E,L
INC E
LD BC, 6912
XOR A
LD (HL),A
LDIR
Anybody remembers what that does? Can be written in a simpler way, but, IIRC, that is still the most efficient way in terms of T-States alone. :)
So, a friend got me the 'Complete ZX Spectrum ROM Disassembly' by Dr.Ian Logan and Dr.Frank O.Hara. The bible of programming Assembly Z80 on the Spectrum! Based on it I ended up doing a copier called 'OmniCopy II' (there was never a version 1) and the thing kind of spread everywhere: the copier got copied eheh. Never put my name on it, so it was bittersweet reading about it in local newspapers and foreign computer magazines... :)
