Which way does the data have to flow? If from the -11 to the PC,
and the data is all simple ASCII, you can just send it out the
serial port without any flow control or error detection/correction.
If it's anything more complicated, I just boot RT-11 and use FILEX
(aka COPY/DOS) to move information back and forth to the DOS-11
packs/tapes, then I use Kermit-RT or TCP/IP on the RT-11 system for
data transfer.

For those who have not heard of this particular recent project, I'm trying
to disassemble the 2K controller ROM in a Commodore D9060 IEEE-4888 hard disk.
Inside the box are a C= board with two 6502s, shared RAM, an IEEE interface
and a SASI interface. The drive mechanism is a Tandon TM602S (5Mb, D9060)
or TM603S (7.5M, D9090). In between is an OMTI 25011 SASI host adapter.
I'm attempting to understand the ROMs enough to either change the drive
geometry to something like an ST-225 (since they are so plentiful) or to
complete the code on the "DOS board", as it's called, to issue SCSI-1 commands
and drive an old 40Mb-200Mb drive at the limit of the Commodore DOS 3.0
physical size (~16Mb, IIRC).
To that end, an understanding of the OMTI would be essential. Does anyone
out there have docs? I have (badly blurred) copies of the schematics, but
no software info. I particularly need to know reads, writes, sense packets
and formatting packets as the OMTI implements them. Most important is to
learn how reduced write current and write precomp cylinders are set. If it's
a command, then that's easy to change. If the OMTI makes assumptions, then
it's not so easy.
I now know where in the code the drive geometry is set; I just don't know
how to affect RWC and precomp, even if I do patch the number of heads and
cylinders.
Thanks,

Since it appears no one can rescue the CDC 9766 drives, I've begun
stripping some bits from one of them (removed one board set already)
and am preparing to remove the PSU during lunch or my next break. Now
then, as time may be in somewhat short supply, can anyone give kindly
me any hints for the easiest way to do this? Noticing the screws in
the side of the slide-out rack, I'm wondering if removing the two
screws on each side will remove it. There also appears to be an
air-hose (used to cool the PSU?) that will have to come off. Is there
some way to eaasily just disconnect the sliding mechanism without
removing the screws? It also looks as though there's some sort of
braided wire (wires?) going into the PSU with no connector that can be
disconencted... blast... the one thing I've misplaced was my
wirecutters, which I, hopefully, won't need.
Any other suggestions for removing any other easily removeable bits
(heads, motor?)?
How do I lift the lid on this drive to access the front panel switches
to remove the switches and light-bulbs? (sorry for the unhackish
question, but time's a bit short).

Much to my surprise I was contacted by someone still maintaining several
PDP-11/55's running DOS/BATCH. Yes, I know I shouldn't have been
surprised, just never heard of anyone actually running it. Anyway, does
anyone know of a way, or have a program to transfer data between the PDP-11
and a laptop? I'm not aware of a DOS/BATCH version of Kermit, which was my
first thought.

Simply put, you plug the board into your Q-bus VAX, cable it
to your HSC/HSD/HSZ/star coupler, install MTI's PQDRIVER,
set up the MTI and VAXCLUSTER license PAKs, and you're on the air!
If you don't have a HSC/HSD/HSZ/star coupler, you don't have much need
for the CIQBA, do you? :-)

I have a TS)3 and a long 19" dual width interface backplane filled with flip
chip modules. I know nothing about it other than I got it 10 years ago in
mint condition.
#1) Is it Unibus or Omnibus or ????
#2) Any idea how to hook it up.. (there are a few slots free at the end of
the plane obviously for cables).
Any help would be appreciated as I have been waiting for docs for the last
10 years.

That was really an ill informed thing to do. I just got (likely the rest
of the list too) a 313kb file! Or better said you spammed the group. Not
all of us have the ability to view it or the patience to download it!
I'd suggest next time finding a web page to post it too next time rather
than filling everyones disks.

Well, maybe my reaction was a little OTT, but some of these things are
fairly hard to come by. I'd like the Hardware Handbook for it's content,
but I know others collect things like CDs and T-shirts for other reasons.
Most such things arn't all that hard to find, though, unless you're
looking for a particular item to complete a "set".
I guess now Acorn Copmputers has been broken up, I could sell all those
teddy bears and sweatshirts to pay for things I really want:-)
