Hi, I've got several Unibus LP11 interfaces and I
was wondering if
anyone
was interested in trading a couple for M8207's
(Q-bus version) of same?
I'd
like to put a centronics printer port on my VAX and
test out some code
in
NetBSD for said port.
M8207?? For unibus or what?
LPV11 for Qbus is M8027 (lp05/la180) but with the right cable kit also
work with LP25/26/27, LN01 and a few others with data products I/F
It wouldn't be hard to use that with Centronics.
other choices are M7941 (DRV11 parallel line unit) or LAV11 printer
interface(M7949).
for most small vaxen the serial interfaced DEC printers was
the common choice. (La50, LA75, LA100, LA210, LA120, LA180, LN03).

Allison's right, an M8027, LPV11 (Q-bus version of the LP11). I'm not
interested in driving a printer with it, I want to talk to a Zip Drive. As
long as I can create a "Centronics" compatible interface (even with all 8
data bits being output only) I have a chance of getting it to talk to the
zip drive. That would give me 100 MB of removable storage, on a PDP-11 that
would be like heaven.

Is the LPV11 a bi-directional port? If you're trying to talk to a Parellel
port Zip Drive I believe that will require a bi-directional port.
Personally for my PDP-11/73 I'm using removable PC SCSI Disk Sleds, this
allows me to use 3.5" SCSI HD's as removable media. I've got two drive bays
in the PDP-11 and another in my Linux box. Plus I've got a bunch of
identical SCSI HD's. The drive bay in my Linux box allows me to make disk
images of the PDP-11's SCSI HD's. Of course this solution requires you to
have a SCSI Adapter for your PDP-11.

Not the old ones, they wrote 8 bits out and did "nybble-i/o" in for
non-bidirectional parallel ports. Makes them significantly slower on
transfer rate but their still faster than an RX50 :-)

And the SCSI adapters are hard to find. Seemed like it would be a good hack
if I could make old (read tossed out) ZIP drives into a PDP disk peripheral.

I have one M7941 that I pulled from some equipment a couple months
ago, I can only assume its in working condition. If you need it
Chuck, its yours.
