I don't know for sure, I only had that one issue to test with. ;)

Block 18/18 sounds familiar, yes. This might be it.

I do not remember all the details, but it was fun to do this. As said,
it was my first attempt on removing a copy protection in order to
generate a backup disk.

BTW: 8/87 had a small note with it, stating that INPUT-Calc had to be
modified in order to work properly. Is that note somewhere preserved?

Otherwise, I could try to find my issue and scan it.

Regards,
Spiro.
