I meant that btst working properly on a data register was good news. I
thought it always just tested 8 bits… All I know is what I read – I haven't
(obviously) tried it out – the 68000 book(s ??) say that the btst instruction
only works on the low 8 bits.
Somebody else here said that is only true if you do it on a memory location –
it works ok in a register. No you say it works ok, no matter what. I am just
cornfused…. Maybe Motorola made a new chip rev, and didn't tell anybody
this had been changed? (Ah – just realized, the 68000 book I read that said
this was by the same guy that wrote AmigaDOG. Draw your own conclusions.) sdb
