I'm sitting in the Tesla room waiting for the IPv6 session to start. We'll see how much stamina I have on Sunday.

If no keyboard is connected the machine defaults to serial console on
the first serial port. (IIRC this is the DB25 one.) 9600 8n1. Before
investing money in a keyboard and mouse you should check if the machine
lives at all via the serial console.

T+40: The Three Greatest Hacks of Apollo (Saturday, 10am, Lovelace Room)
Vintage Computing -- Evan/Bill (Saturday, noon, Lovelace Room)
The Telephone Pioneers of America (Saturday, 8pm, Bell Room)
2600 Meetings: Yesterday, Today, and Tomorrow (Saturday, 10pm, Lovelace
Room)
Sunday:
Cats and Mice: The Phone Company, the FBI, and the Phone Phreaks
(Sunday, noon, Tesla Room)
Simpsons Already Did It - Where Do You Think the Name "Trojan" Came From

RTEM might be something else than RTEM-11, which was a software product
for RSX. Just google for RTEM-11, and you'll find some references for it.
However, I wonder about RTEM for VAX. It's certainly possible, but I
can't find any other reference to it, and DEC's old SPDs, especially
those with software version compatiblity matrixes, are usually pretty
good as a way of finding out what software existed.
As for PDP-11 compatibility in VAXen, yes, the 86x0 machines have that.
Those were the last, however.
For all other VAXen running VMS, if you wanted to run RSX software, you
needed a PDP-11 emulator product for VMS, which was available, in
addition to the RSX additions for VMS, which was also a separate
product. That thing was supported up until fairly recently, though.
But again, that's for RSX stuff...

But of course! Opus Systems, like Definicon, put a couple of different
CPUs on full-length ISA cards that would be added to or bundled with PCs
to create a lower cost workstation in the latter half of the 80s. Opus
delivered products using the Nat Semi 32000 family, later developed the
Personal Mainframe Series 8000 using an 88k chipset, and eventually did
it again with SPARC. We had one of these 88k boards in a Compaq DeskPro
on a researcher's desk in 1991 and he was quite pleased with it.
If one of these 32k or 88k systems/boards should need a new home, feel
free to give me a shout. ;^)

Hello. I sent this request initially to PDP8-Lovers list, but I send the
same request here in the confidence of some help.
I am cleaning one PDP8E box with some boards inside. Previously to do some
cleaning of the internal boards, I tried to fire up the computer yesterday.
In appeareance nothing is wrong no strange smells, no burns, no clouds, no
boom!, etc...)
But... I don't have the front key :-)
One ACE xx2247 is needed. I don't have one available, and is impossible for
me to get one in my country (Spain).
I would be grateful is someone could provide me one, or even a couple.
Contact me off list if you want to discuss details.
Regards
Sergio

As far as I know, RTEM-11 will not run under VMS.
It was a product for RSX-11M (only). Long since retired now, and I don't
have any details on it. However, I seem to remember that when you do an
-11M SYSGEN, you still get a question for some RTEM-11 support to be
included in the system.
As expected, it will trap RT11 EMTs, but exactly what it will do for
specific EMTs, and in which cases it might differ from RT11, I have no
idea. It's probably also not compatible with any "recent" changes to
RT11, just so that you know...

I have fixed some of the bugs in a program which runs under RT-11
(obviously using the
PDP-11 instruction set - since actual DEC PDP-11 hardware can be
replaced by either
other compatible hardware on an emulator such as SIMH or E11).
The bugs were causing problems when the program was run under VBGEXE,
especially
when the program was run as a system job.
The requirements for the changes and additions to the RT-11 code have
been determined.
However, the same program is expected to run under RSTS/E (using SWITCH
RT11),
TSX-Plus (which is fully compatible) and RTEM-11. It is this last
expectation for which I
have been unable to find any documentation, let alone any ability to
test the program. Does
anyone who is reading this know where there might be documentation
available concerning
how RTEM-11 handles RT-11 EMT requests? In addition, does anyone know
of any
systems currently running which support RTEM-11 features which allow
RT-11 programs
to run in that environment? My assumption is that VMS on a VAX
supported RTEM-11
at some point, but perhaps (if I am correct) the RTEM-11 support was not
continued with
more recent versions of VMS on the VAX and most definitely VMS on the
Alpha. Can
anyone comment on these questions?
