The 11/15 I have appears to be a KC11 with KY-11C console board. I have the
complete print set for this 11/15, a while ago I was asked for a partial scan of
the KY-11C pages by another 11/15 owner as it differed sufficiently from the
11/20 print set and apparently the scan was just what was needed. I don't know if
that person is on cctalk though, if so please pipe up.

Since I have not found this anywhere (please correct me accordingly) I hope to get
to scan the 11/15 print set, on my little A4 scanner it's going to take rather a
lot of time.
