timera.asm:
- hooks a timer interrupt (VIA2 timer A) and reads from another timer (VIA1
timer A) which creates a typical pattern.
Note: the first number (and thus the entire pattern) seems to not only depend
on the type of mechanic used in the drive, but also in the state the
drive was before (preferably before running the test, first load the
directory so the head is on track 18, then powercycle the drive and run
the test)
