	The machine I learned to program on was an "LGP-30" with 4K
(24 bit) words of drum memory. The only language available was machine
language (not assembler) though it was easy to learn as there were
only 16 machine language instructions. The hardest part was learning
the (now lost) art of optimising(sp?) drum accesses (NOT easy). I/O
consisted of a terminal like thing called (I think) a flexowriter, and
a "high speed" paper tape reader and punch (also many buttons & lights).
