Hi Gang:

I have an original model PDP-8 (core serial number 35) which I no longer
have space for. It's the tabletop model with smoked plastic covers. I
would like to give it to a museum that could take care of it and
hopefully display it. If any of you know of a place that would be
interested, please let me know.
Thanks.

I just acquired an Intel Series III MDS "blue box", to go along with
several Series IIs that I've had for a while.
Unfortunately, I don't have any software or documentation for either
the Series II or Series III, not even the ISIS operating system. If
anyone has spares or could make copies available, it would be most
appreciated.
For those not familiar with the Intel blue boxes:
The Series II MDS is Multibus-based, and has either an IPB-80 or IPC-85
CPU card, based on the 8080 and 8085, respectively. There's also an IOC
(Input/Output Card) that supports all of the integral I/O devices such
as the monitor, keyboard, serial ports, and single-density floppy disk.
An external double-density floppy disk system can be added; it uses two
Multibus cards, a channel card and an interface card, and apparently uses
M2FM code rather than IBM 3740-compatible MFM. The Series II normally runs
the ISIS operating system, although I hear there was also a version of CP/M.
A Series III MDS is mostly the same as a Series II with an IPC-85, but
it adds a two-board RPC-86, which is an 8086-based "Resident Processor
Card". A software package called "RUN" acts as the loader and ISIS
operating system interface for the 8086.
I'll second that!
Thanks Jay!!

Apologies if anyone already got this; I originally posted it during what
seems to have been an outage, and I assume the original is lost...

Nope, Pete was wrong again. It looks like MSCP support first appeared in
4.0. And I never did get my RQDX3 to work under RSX-11 (but I never had a
version later than 4.2).

I've never done an install from tape, except to recover a backup, and then
what matters is what standalone BRU or DSC supports. In 4.2 at least, BRU
and BRU64K.SYS (the standalone) do support MSCP, but the manual only lists
RA80/RA60/RA81/RC25/RD51/RX50 disks (and no MSCP tapes at all). DSC only
supports the RA80; standalone DSC has no MSCP support at all in 4.2. I'd
expect 4.0 supports even less.
The list above implies RQDX1 support and other things, but not RQDX3. That
might be a problem, because I think there's a bug in the early DU: handler
that prevents it working with RQDX3s. I certainly never got RSX-11 4.2 to
work with any RQDX3, and the same bug might apply to a 3rd-party
controller.
Best way to find out is to try it. I reckon there's a reasonable chance
it will work, especially if your disk controller works with RT-11 5.1.
In RT-11, full MSCP support post-dates even 5.1. 5.1 works with RQDX1/2,
but not RQDX3, for example; because whoever wrote the DU: handler ignored
the MSCP documentation and made an unwarranted assumption about the
contents of the SA register during initialisation. It took me ages to
trace the problem and fix it :-).

This apparently didn't make it out to the list.
I was cleaning a TF85 (DSSI desktop model) and discovered that the drive
talks to a bridgeboard that talks DSSI. The connector to the drive is the
same number of pins as the TK70 drive. My question is whether or not one
can drive the TK85 mechanism from a TQK70. I ask because I would like to
put the drive inside a cabinet (BA213) and would rather not have the bridge
board laying in there as well.

Guys:
Could any of you use a few RL02K-DC disk packs?
I have three of them, shock-watches intact on two--
the third one doesn't have it.

covered time period starts with the IIci and Portable, which are
topical by the ten-year rule, but we can always hope for more...

Don't ask any specifics, I don't know them, and I've not seen the system.
The Hillsboro "Wacky Willies" currenty has a largish HP system in back
(you'd have to ask about it, I was in there yesterday and didn't even see
it as they've blocked of the entire back half of the store). From what I
was told it's at least one 19" rack, and bunch of terminals, lots of
documentation, and I think tapes. I gather it might be something like a
735?
Again, I know nothing about this system, someone I know that messes with
DEC and Sun stuff spotted it and thought I might know someone that's
interested. He said it's *over* a pickup worth of stuff!
