Hello Ruud, >It is nice to know that my module could work if I added those buffers but >with no explanation I'm not very willing to do that. What still puzzles me >is: why does the garbage only appear during loading??? If there is a >conflict with the VIC, why does the garbage not appear during normal >operation? The CIA chips I've heard (I think it was some discussion on the SCPU's design) has some different access characteristics, and the host CPU needs to be compatible. During a LOAD CIA#2 is used. Have you tried something like this to see if the conflict is to do solely with the CIA? If so, you should get the garble characters. loop lda $DD00 jmp loop PLEASE TAKE NOTE: The contents of this email (including any attachments) may be privileged and confidential.
