The space for the Floppy is being taken up by the TK50 (figuring
you have one, given that you have the controller for it)

A *terminal* of some sort is needed, unless you get the VCB02 (QDSS,

Hi folks,
Briefly, I have a Microvax II that I got in that big haul of DEC gear this
past July. I'm trying to find time to check the machine out. First, I need
to ask the MVII gurus whether I need to have bus terminators in the last
empty slots. I'm not exactly sure if Qbus needs terminators like Unibus. So
far to now, I haven't found a FAQ or website which addresses this exact
question. I just need to be sure in case the machine has a problem coming
up and I can rule bus terms out. Here's the board compliment as I got the
machine:
The chassis is a BA23. Machine's model # is 630QY-A2
Slot 1: M7606 EF (KA630-AA w/1mB RAM, F.P., T.O.Y. clock, boot/diag. ROM)
2: M7608 BP (MS630-BB, 4mB RAM)
3: M9047 (Grant continuity card)
4: M3104 DHV11-A, 8-line async. comm. card)
5: A-B side: M7546 (TQK50-AA, TK50 controller)
5: C-D side: M7555 (RQDX3, Win./FD controller)
6: <empty>
7: <empty>
8: <empty>
9: <empty>
FWIW: the hard disk is an RD53, there's no FD.
I also got a raggy looking VT220 I still need to check out which I
understand is needed for MVII's.
The Ethernet modules were already missing from the two big VAXen and maybe
>from one of the PDPs that I got in that haul so there could have been
Ethernet cards in a couple of these MVII slots which could account for part
of the empties. Would like to wire Ethernet into this house to interconnect
machines, but first things first (such as *finishing* work on the house and
getting machines to just _run_!)
Other than the obvious, such as checking PSU, etc. before lighting it up,
are there any other words of wisdom or MVII info sources anyone could
direct me to? I have basically no documentation except for most of a set of
VMS 5.4 manuals -and I of course do not yet know what OS this machine runs
(but likely VMS of some version I suspect.)
There's a few online URLs I have scrounged that have some MVII info bits
but as I said, none talk specifically about this bus thing. (So maybe it's
a non-issue but I don't know . . .)
Thanks gang!
Regards, Chris

With what I picked up yesteray, I now have the reasonable
beginnings of a collection of older IBM manuals and disks for desktop
PC's, XT's, AT''s and PCjr. While I'm not offering any to give or sell,
if there is any information anyone could use from any of these I'd be
happy to dig it out. I know someone from either this list or from the
computer folklore newsgroup was looking for the Technical Reference Manual
for Personal Computer AT. It is truly an awesome text. Here is what I
have. Unless otherwise noted, they contain the disks that came with them:
-Technical Reference Personal Computer AT
-Hardware Maintenance Reference:Personal Computer Systems
-Guide to Operations: Personal Computer (PC)
-Guide to Operations: Personal Computer XT
-Guide to Operations: Personal Computer AT
-Guide to Operations: Personal Computer PCjr
Languages:
-Pascal Compiler ver.2.00 vol.1
-Basic ver.3.0 (no disks)
-Basic Compiler/2
-Macro Assembler 1st edition
-Sort
OS's:
-IBM Dos ver. 2.1, 3.1,3.3, and a copy of 1.1 but no manual
I would love to eventually scan all these and have disk images on a web
page but I can't afford the lawyers I'd need to stay out of jail :-(

Hi Group:
I'm late to this thread, but if it hasn't been mentioned already, I recall
that both Voyager I and Voyager II space probes were 4004 based in their
control/housekeeping units.
I see from the JPL pages that regular communications with Voyager have
just recently ceased, and that they are well beyond Pluto and above the
plane of the solar system, next system to be reached in about 20000 years.

I found a 3M CompacTape for Intellegent Query and IQ Access:at the bottom of
a box of goodies. Almost off topic, except that the other contents of the
box were 10+ years old... details follow.

Ok, then I will ask you guys..
I recently obtained an Altair 8800. I would like to get a hold of any
notes/manuals/journals or SCANNED versions of these documents.. to help me
with my restoration and also to possibly publish on my web site (its under
development, but you will hear from me when it is done!)
Who has info?

That describes many devices that use Texas Instruments TMS100
and descendants instead of 4004's :-).
How come people are so hot after 4004's and 8008's - even ripping
up PDP-11/34a's to get at the 8008's inside, for example - when nobody
cares about the TMS100's?

That's odd. I had an SX-33 386 that (not counting bootup) actually ran things
a bit faster under 95 than it did under 3.11
(This with 4megs ram and an 80mb harddisk)
