I have just such a board that was a pull from an RS/6000. I wasn't aware
that many of them sold for use in PS/2. In fact, their use in the machines
(IIRC) was originally just for testing purposes because they booted faster
than the RS/6000s ;)
Nice board. Wish I could do something with it (Like get an rs/6000 and
software to drive it!) :)

No thanks! I think I'll stay away from your neck of the woods! It's bad
enough here! In the last five years there have been a dozen shootings and
one murder within a quarter-mile radius from my shop. I keep the place
looking run-down so I won't get robbed. Not to imply that all these crimes
were committed by black folk -- but the fact is that most of them were . .

Gaps are programmable too. There are two things the 765 will not do:
Munged
wacky formats like using deleted address mark for address mark {you can post
format with deleted data} and it was not designed to pump out all the raw
bits/splices/marks from the media.
Things it did do that the WD never had: Multiple seeks or recals, timing
for the
stepper, head load delay, head settle delay.
The biggest difference: register based programming vs command packet to a
"port".
I've used both and someplaces one or the other is better. On the whole the
WD
parts always seemed to be first generation. The upside for the 765 based
was
the very highly integrated super chips like the 36c766 and later.

Here's a PDP-11/34 with RK05 drives available. If I had
somewhere to put it, I wouldn't mind picking it up myself as it's
only a few hours from here. But no room....so, I'm passing it on to
the group. Please reply to the original poster shown below.

Well, that's disappointing, but 4D is still nice.
I do have my heart set on eventually running an m68k-based SGI though.

Anybody got the pinout for the following:
DEC 380 bus receiver
DEC 97401 bus receiver
DEC 384 (or DEC 5384, which I think is the same) bus driver
Are any of these similar to an 8880, 8881, or 8640? Or to any of the 8Txx
or any more modern ICs?
I'm trying to fix an interrupt fault on my PDP-8/E, and having a bit of
trouble following the circuit. My M8650 isn't quite the same as the
diagrams in the Maintenance Manual :-(

Is this Darwinian? That is, do people who lose their common sense
and become stupid just naturally rise up into management (a la
The Peter Principle)? Or do they willingly learn to be stupid
once they rise up into management?
Chris, you're management, so I know this isn't universal (how
has your brain survived?) but it's damned prolifigate...

My 8/E 4k core looked to be about 40 gauge. The 8/E also had an 8k core
and the 8/A a 16k core. They would be even smaller.
Here is my pictures of the PDP-8/E 4kx12 core board.

Well, you have a good image. That's a start.

Was it just the MBR that got nuked? Lots of times on intel systems, those
are similar if not identical. All the boot-loader magic is handled in the
second-stage loader near the beginning of the partition, or something like
that. :)
If that is the case, you may be able to replace it with the MBR from an
MS-DOS bootable hard-disk. Also the DOS command FDISK/MBR is known to
restore the MBR to such a state that at least MS-DOS will boot. If Xenix
expected the standard DOS MBR, you'd be all set.
So you could try making an MS-DOS bootable floppy, copying FDISK.EXE to the
floppy, booting the machine from that and running the command. If the Xenix
MBR really is different, then you may still be able to get away with using
the DOS loader, provided there's a second-stage boot-loader in the right
place on the Xenix partition. You would just use FDISK to set the bootable
partition flag on the partition you'd like to boot, and the DOS boot-loader
will try to pass control to a second-stage on that partition.
Once you got in, of course, you could re-install the proper Xenix
boot-loader (instboot?)
I would back up the MBR first. I think there are utilities with most
boot-loader apps that will do that.
(Note that this is more-or-less speculative, but I'd like to know if you try
it, and specifically, whether it works)
