Hallo allemaal,

At this moment I'm invertorying my room. In just two hours I found a lot of
things I didn't even know about anymore :) I also found several little boxes
with C= IC's. I have some questions about them. As you probably know, I
asked you to bring in a list with all the partnumber you knew. The following
three were marked as "6530-equivalents" by someone. Yesterday I found them
but they all are 24 pins so IMHO it are ROMs.
901467-01
901887-01
901888-01
Anyone an idea?

I also found a 6581R4. The strange thing is that all my other 6581's are
marked as "6581" only. What do I have here?

Last item: I found two 6526B's, the 3 MHz version I assume. Didn't know that
they existed at all. Where were they used?

Thanks for any info.

Groetjes, Ruud
