A few days ago, I submitted a short assembly language program (written
by Thom Sterling) to DL1 (hardware), which demonstrates how the disk drive
stepper motor rate can be set from software. It also exercises one of the
Amiga's hardware timers, and incidentally demonstrates that the multitasking
system can recover gracefully after interrupts have been disabled for a
>>long<< time, unlike what the manuals would lead one to believe.
The program looks like it's fine. I don't do the DLs, though; Wizop George
does. He takes a variable length of time to make stuff visible… I'm not
sure what the delay is in this case. I'll bother him… ;-} – Bela
