Is the protocol that goes to the tape head in a QIC02 drive similar to
QIC36?
The protocols for the read/write signals (essentially the bit format on
the tape) are (part of) things like QIC-11, QIC-24, etc. And yes, the
same protocols can be used in both QIC02 and QIC36 drives.
In fact both my QIC02 host-interfaced drives (A Wangtek
something-or-other and an Archive Sidewider) are actually QIC36 mechanims
with QIC02-QIC36 bridges mounted on them.

IIRC,
QIC-02 uses handshaking; QIC-36 does not.
YEs. That's because QIC36 is a low-level 'raw' interfce, you're talking
to the read/write head almost directly (a bit like a floppy drive
interface), whereas QIC02 is a much higher level 'formatted' interface, a
it like SCSI.
