Just out of curiosity, we took a brand new TK50 and wrote a backup
saveset to it on a TK70. It worked OK. However, as a matter of
principle we do not intend to use TK50s this way. I can't comment
on the reliability, but using BACKUP it should be OK even with a
few soft errors.

What really irked us however, was that in the easly days of TK70s
we could not get many and one of the operators mistakenly used a
few in a TK50 drive one day. Result -- TK70s that you can no
longer use except as TK50s. You cannot even re-initialise them
because the "smart" drive checks the tape first and says "Oh no,
this is a TK50!".
