 I know that I posted some inquiries about MPU 401 code in Pascal -
got hardly any response so I guess hardly anyones working on music in
pascal... Anyway I have another question - I have a routines that
installs itself as a device driver reliably with int(s)
27 hex 1b (CTRL break) - dec 28 hex 1C (clock tick int)
and dec 5 Hex 5 ( print screen ) ------- it works as you might
expect, taking over whenever the INT is invoked. Can anyone tell me
why it doesn't work with hex 0A? This is supposed to be the interrupt
dec 10 address 0028  for the MPU-401. I'm so close at making this work and
it doesn't!!! Why would it work with all the other interrupts and not
with int 10? it just sits there and does nothing...
If anyone knows interrupt handling in pascal please reply..
else 'C' is looking very good nowdays..................
