Aagh, I forgot about the HP85 some instrument programs where written for those.
So you have to check the part numbers of the tape and look in the service manuals to see where the tapes are for.
The 9875A and 9877A are external tape drives for the DC100A tapes almost unobtainable like the HP 9831A which is also very rare (I know just 3 including mine) .
The only 9875A and 9877A I know are at both the HP Museums.
