Aye. The graphics primitives, and just about everything else, too. A lot of thought went into making those machines conveniently programmable which made them great for both learning and tinkering.

Though the main two reasons I had for assembly were faster maths loops and graphics (via direct access to screen memory including, on the Master, the shadow screen for double-buffered drawing), so neither of those parts where sometime I called much.
