I've got a Wangtek QIC-36-
Most of them certainly do. QIC02 to the host and QIC36 to the drive.
I have (and still use) an old Archive Sidewinder drive. It's old enough
that it's 8" form factor, and needs +5V and +24V. On the metal frame is
the drive iteslf and a stacked pair of PCBs that form the controller. The
interface to the host is QIC02, the interface between the drive and
controller is QIC36 (or something very close to it).
to-QIC-02
bridge board (QIC-36 is the "basic stupid" interface, while
QIC-02 is the "intelligent buffered" interface).
Entirely possible. I've got various QIC drives that I use occasionally, but
nothing that's '02 or '36.
I suppose in theory the protocol/interface might be documented somewhere such
that a suitable high-speed parallel port (of sufficient data width) might be
able to talk to a QIC-02 drive - but that's a lot of effort for something that
then wouldn't be particularly portable.
The QIC02 interface is pretty simple. 8 data lines and a handful of
control/handshake lines (I think fewer than 8 of those). The control
lines, from what I remmeber are all unidirecional (obviously some from
drive to host, others from host to dive), the data lines are
bidirectional (but all in the same direaction at any given time).
I think the interface can be bit-banged. If not (i.e. there are some
critical timings), then it's can be handled with a very little amount of
logic. The PERQ QIC02 interface is a handful of TTL chips, I managed to
fit it in the prototyping area of a OIO board
I would be suprised if the QIC02 specificiation isn't avaiable somewhere...
