As you already know I got this Tek 611 Thing working lately
and now I think about connecting that Beast to one of the PDP11 systems I
have. They all are QBUS 11's, (12,53,83).
Joachim gave me the hint to use a DRV11 or an DRV11-WA to connect the
needed D/A Converters to supply the Tek611.
I do have both DRV11 Variants.
Now I'm looked in the 2.11BSDs sources and found a driver for DR11 boards,
which looks like a similar parallel interface for the UNIbus.
(I'm a Unix guy, and using BSD may be the fastest way for me to get this to
work).
How similar are the 3 interaces to each other? Is is worth to begin with
the DR11 driver..?
I've don't looked deep in the DR11 Manual and I dont even have one for the
DRV11 Boards (...has someone a Hardware/Programming Manual?) so I'm
primarely asking here for some experiences from other people..
Kind Regards,
Holm

The DR11s are parallel interfacess for Unibus, and there are at least 5
of them :
DR11-A was the first one. Originally it was a dual-height card which you
used along with an M105 address selector and M782 interrupt logic board.
The device conencotr was a dual DEC edge conenctor block o nteh top edge
of the card. IIRC this looks to software much like a DL11 -- transmit and
receiver data registers (16 bits each I think) and a CSR for each.
DR11-B was the first DMA parallel itnerface. It was a custom-wired 4-slot
system unit backplane
DR11-C was an improved DR11-A I think.
DR11-K was part of the 'lab peripherals' set, I can't rememebr waht it
did that the otehrs didn't, I would have to dig out the docs
DR11-W was an improved DR11-B on one hex card. I think it added some more
featrues. It was certianly a DMA device.

IIRC a plain DRV11 is the Q-bus veraion of a DR11-C. A DRV11-W is a Qbus
DR11-W. There prgramming interface fo the Unibus and Qbus versions is
much the same. but the non-DMA and DMA cards are very different to program.

THX Tony, what I wanted to know is pretty much that what you wrote in your
last sentence. I don't think that I want to fiddle with the DMA capable
Interface at the first time. The Speed isn't that much interresting for use
with the Tek Display.
Thank you very much.
