SDSTOLLE@PUCC.BITNET (Scott Stoller) (01/19/87)
I have Abacus PAscal on my C=64, and would like to use it with the integrated
assembler to write a music playback routine. However, it seems that SID
cannot be accessed in the usual manner, i.e., simply 'pokeing' using the
MEM[$d201] = .... I tried this and nothing happened. Any suggestions?
Thanks.

First of all, double check that the SID is being properly initialized using the above addressing. Then, if still no noise, look carefully through the Pascal implementation documentation. It is possible that Abacus decided to implement the MEM array with bank-switching into RAM under I/O, thinking that people might rather store data in hidden RAM. This is pure speculation on my part, since such a move on the vendor's part would not be a good one...the command should work as expected. Perhaps you could set up a bunch of constants holding SID registers for yourself as an alternative...see if that works. Bob Dickow (...egg-id!ui3!dickow)
