I modified a HP 9825A tape drive for use with QIC
40/80 tapes.
It's a rather easy conversion building a new capstand wheel witch is a
little higher so it can drive the QIC tapes and increasing the write current
by replacing a the current limiter resistor.
It's under test and at the moment seems to work.
I was curious if there others who did the same and what theire experiances
are...
I've never tried any such modifications, but if you can poit me at
details I might well give them a go. I wonder if the HP9815 can be
modified the same way (it's the save drive and head switch/amplifier
PCB, buit with a totally different controller).
