If I'm not mistaken, Tandberg is still cranking out the 5.25" QIC drives. I
have a TDC-4100 on my desktop and it's a tank.
The QIC Standards folk have a web site, which seems to be unreachable at the
moment: http://www.qic.org
Last time I visited, they had a nice table of QIC standard formats there.
Could you give an example where we may have seen a QIC36 or QIC02 tape? It
doesn't ring a bell here.
The tapes are DC300, DC450, DC600, DC6150, DC6250, DC6350 etc.
They've been used in everything from Sun and other Unix workstations
through PDP's to early PC/XT's.
Common manufacturers were Archive, Techmar, Tandberg.
QIC-36 and QIC-02 were the interface standards for the
drives. QIC-36 and QIC-02 drives often could interchange tapes.
The difference was the amount of smarts in the controller vs. the
tape drive (I seem to remember).
My PC and some workstations used QIC-36 tape drives with a QIC36-QIC02
converter board.
Some of these also used QIC-36 or QIC-02 to SCSI converters.
