Hi @ll,

maybe this one is interesting for some of you:

MOS internal Documentation about 6522 problems and possible corrections (that were never made).

Attachment:
MCS6522_Problems_and_corrections.pdf [643.44 KiB]

Please excuse the slightly too small scan. I don't have a Scanner for this paper format (yet).

Very interesting! I came across problem 3 quite recently. I believe problem 8 was solved as it is possible to clear individual IFR bits now.
