Does anyone know offhand if the CXY08 (M3119) and DELQA (M7516) work with
2.11bsd?
I think the CXY08 has the same programmer interface as the DHV11, and I'm
hoping it works with the 2.11bsd dh driver. Ditto for the DELQA and the qe
driver. If somebody knows for sure, though, I'd appreciate it if you can
save me the trouble of installing it all just to find out it doesn't work.
Thanks,
Bob

The DELQA should work fine with the qe driver.? I can't comment on the
CXY08 as I've never tried it personally.

FWIW, looks like the CXY08 in DHV mode works find with 2.11bsd.
The qt driver, however only works if you have the very late model DELQA that has
"turbo" mode. I think that was called the DETQA, but I'm not sure about
that. If you have an earlier DELQA then the qt driver simply says "qt0: !Turbo"
and quits. Gotta love those terse Un*x error messages!
The older non-turbo DELQAs and the DESQA (M3127, which is what I have) only seem to work
with the qe driver. It correctly recognizes and identifies them as a DELQA. I believe
the DESQA was identical to the DELQA but with S-box handles and a built in thinwire
transceiver.

Are there any hardware differences between the M7516 non-turbo and the
M7516-YM turbo versions of the DELQA, or only firmware differences?
Can you convert a non-turbo version into a turbo version just be
replacing the firmware EPROM?
I just checked and I have at least two M3127 DESQA. The M3127-PA Rev
B02 has 23-334E5 / 23-335E5 firmware EPROMs, the M3127-PA Rev D03 has
23-365E5 / 23-366E5 EPROMs.
Pete's DECROMs collection says the 23-365E5 / 23-366E5 set is the
DELQA-Plus aka Turbo DELQA Ver.2.0.0 set which replaces the 23-334E5 /
23-335E5 set.
If you have some spare 27C128 EPROMs you could try burning a 23-365E5
/ 23-366E5 set to install in your M3127 DESQA and see if the qt driver
is happy with it. I might try that myself eventually when time
permits.
For the curious about the 2.11BSD "qt0: !Turbo" error message:
src\sys\pdpif\if_qt.c:

addr->arqr = ARQR_SR;
addr->arqr = 0;
delay(150L);

if (i != 0x8001)

return(0);

The non-turbo I've seen use an AMD Lance ethernet chip (Am7990), while the
turbo I've seen use a DEC chip in its place. Could be important, or could
be coincidence.

AM7990DC/80 chips, with DEC 21-21672-09 part numbers.
(The main obvious difference between the B02 and D03 revisions is
header block jumpers vs push-button switch transceiver selection).
Found this thread on the subject from back in 2011. Doesn't seem to
include actual results of attempting a firmware only swap.

At least he's not trying to use a DEQNA interface, so he's ahead of the
game...
