Thanks a lot for the manuals and schematics. Will be really helpful when I
get to work with RC11/RS64.
You don't happen to have the diagnostic listings as well? I found a ZRCAB0
and ZRCBB0 diagnostic but not any matching listing. Haven't found a ZRCC

So, if you have diagnostics listings and matching binaries or just listings
that would be very interesting as well.

Then one definitely need the track writer I guess. But it is good to know
that it is possible to flip the disk if it is in bad condition.
