Actually, you wouldn't, that's one of the big differences between the
RQDX1/2 and RQDX3. The 1/2 perform various tricks to try to work out what
disk is connected, especially when formatting. The tricks vary between
versions of the firmware, so I have a 10MB Rodime disk which one RQDX2
version will "recognise" and format but other versions won't. Several
years ago, I had an interesting email conversation with Chuck O'Toole who
wrote the sniffer code (and most of the MSCP, geometry, and access code)
for the RQDX1, which is part of the DUP utilities in the firmware. It was
intended to autosize certain known drive types that DEC would/might sell,
to differentiate between them, and it was known that the succesor
(eventually, the RQDX3) would be along later, so there was no great
incentive to make it fully general.
However, the RQDX3 doesn't depend on the tricks. The formatter doesn't
rely on DUP utilities built into the RQDX firmware but uses tables in the
formatter software (XXDP ZRQC??.BIN). It only uses the DUP utilities to
perform the actual track formatting. There's an option to force it to use
a table entry of your choice (including entries for common drives like
ST-251 and ST225) and even an option to bypass the tables and enter all the
necessary values by hand, though it takes a bit of effort to work out what
they all should be for any given drive. Tim Shoppa posted some information
to the list in 1997 about the makeup of the various numbers, and I have
some more in some manuals which I might be persuaded to dig out if anyone
is really enthusiastic. It would still take a bit of exprimentation and
guesswork, though.
DEC's patent describes the basic ideas and the TLAs:

Hi,
today I received the PCS module replacement I needed for the 11/780.
And it helped indeed. See the transcript below. I do get some timeout
at step 54, please have a look. I don't know what the problem is.
May be it was going to test the DW780 and I didn't have the UNIBUS
cabinet powered?
Thanks,

Okay, dug out the Apple ][e, DuoDisk, and ImageWriter II I was given some
time back, got a SuperSerial card installed and configured and the
ImageWriter II works fine. DuoDisk works too, but what is the command to
select a specific drive?
At this point all I can read/write to is the boot drive (left-most drive)

Hello, all:
I'm seeking opinions on long-term PC board storage. Is it better for
longer term storage of "classic" boards to individually pack them in "metal
out" static bags and store them in conventional cardboard boxes or should I
buy a few static dissipative cardboard boxes or Bentron plastic totes and
store the boards there?

SYDNEY!!!! They're *very* nasty, ranks up there as about the most
deadly spider in the world, the females bite can kill within 2 hours,
the males within 15 minutes. However, …
[View More]they generally don't lurk in old
computers :-) Shoes, clothes & beds are better :-)
Deaths are fairly rare though, anti venom has been available for some
time.
This thread recently came up in the Fidonet SF echo too, wonder if it's
spreading.....

It seems to be the wave of the present for automated mailing lists.
Personally I miss the days when, given a list addressed "list@host",
list-request@host could reasonably be assumed to be read by someone
who understood words like "please", or at least didn't reply to such
words with an error report. I like automated list-management software

[View More]too, I just don't appreciate the change of the old convention.
