Yes, interrupt occurs every frame, at the time of the blanking pulse, what is every 20 ms.

It's not true.
Try this: http://pmd85.borik.net/_work/test-int.ptp
Start it JUMP 0100, then key Shift displays time counter.
But you must use monit2B.rom for PMD 85-2 or PMD 85-2A.

yes, right! ;)
I forgot about EI at interrupt handler(((((
And last question:
Where to read about values of beeper port $F6?
And how values for keyboard scan defined? Seems like row at keyboard must be defined.
