I had a quick look and actually this was caused by Lau trying to save
2 bytes. When you look at io_serio_asm
io_pend
* moveq #0,d0 test routine is the first element
bsr.s vectest set up test routine address
bra.s callit go do it
you see that the moveq is commented out because "d0 is 0 anyway!".
Well, except in the case when io_pend is called through headr1, in
this case D0 has some other value and the whole thing will crash.
I hope you can now resume more productive work :-)
