I have a 'new' microVAX 4000-200 here that has a few small oddities
with it, and I could use some advice. Number one is that it will not boot.
I tried 'b dia0' and 'b/r5:e0000001 dia0' and both times it's nothing until
timeout. Number two is that 'show dssi' and 'sho dev' show no disks, nor
the TF85. After some initial confusion where one or more disks were
tried uncabled before powerup, the DSSI terminator was discovered
missing, so I used one from another machine.
My questions are, are there other tests for a disk besides booting it,
and, what could be wrong with the DSSI bus?
I tried other DSSI ID's on the disks but no real change.
Do the ID's have to start with 0?
A tidbit with the terminator off was that the countdown tests went from
95.. to 60.. and then autobooted immediately back to 95 without continuing
down. I could have sworn at the time that 'sho dssi' worked then.
Probably unreleted but FYI.

I was channel flipping and came across a movie on The Disney Channel where
a guy was standing in front of the front panel of a computer with tape
drives spinning in the background. He was doing some demonstration for
three men, pushing buttons and flipping switches on the front panel and
then the computer was spitting out results on punch card from the front
(this part was fake). At first I thought it was a recent film. I thought
the tape drives looked very authentic, because their movement was very
real. Then I looked at the front panel and saw "Siemens System 4004", and
was quite surprised.
It turns out the movie is "Willy Wonka and the Chocolate Factory". The
last time I saw this was probably 15 years ago.
The Siemens System 4004 is very interesting in this context. According to
Hans, it is the first fully transistorized digital computer, beating out
even the MIT TX-0. The Austrian Mail?fterl also vies for the title, but
Hans Franke claims it wasn't fully completed or something:

A quick Google search turned up a computer that I was not previously aware
of:
http://www.pbs.org/transistor/background1/events/sscomputer.html
This is the TRADIC (TRAnsistorized DIgital Computer) built by Bell Labs.
If the year is correct, I believe this is a contender for the title.
This site says 1955:

Here's a couple pages on the Siemens 4004:

Pretty cool stuff.
Is anyone still keeping track of these vintage computer movie appearances?
This one is pretty significant ;)

I just picked up an IBM PC3270 with the 122 key keyboard. The 122 key
keyboard has a 5 pin connector, but the pins are in different positions so
it won't plug into to the keyboard socket as is. I assume there is an
adapter that it usually included. Does anyone have the pinout?
It does boot with a standard XT keyboard, but give a 302 error. It would
be nice to use the original keyboard if I can.
Hi, John,
I do have one - I never dumped it, because I loved those (bloody) 630's
I's a metal one with the USA Titan10 character set, never used...
You can have it if you want it...
I might have the service manuals of this 630 too - somewhere...

Does anybody have any spare daisywheels for a Diablo 630
printer? I have one of these printers, apparently complete
and working, but without a daisywheel. Alternatively, does
anybody here want it, as it is?
I'm in Bristol, UK.

I think that what may be wrong is a simple pull-up or pull-down resistor
(which may explain why the setup works with the bus analyser connected).
NRFD and NDAC are supposed to be "weakly" pulled high (so that even one
device pulling it low wins), so your 1350 may be allowing this line to
float rather than pulling it high. If the bus analyser is connected, it
will pull the line high (since the 1350 is floating the line) and the
bus cycle will work. With the bus analyzer removed, the line stays floating
and the cycle freezes.
Hi folks,
For some reason, I've gotten the bug to get some of my Intel Development
Systems working again, and it seems that the main part I need is the
floppy drive. The Intels use single sided, double density drives. All
mine have Shugart 800/801 variety. I would like to buy two or three of
them, preferable working. If anyone would like to sell up to three of
them, please let me know.
Also, if there is anyone local to me (Detroit area) who would like a
working Intel Series II development system, I have one to sell.
Everything is checked out and works. I really don't want to ship it.
It is a major hassle to palletize it and then shipping costs about $150
because of the weight. So, local only for now.
Thanks.
Dave

Hi,
I'm looking for a PDP-11 bootstrap for a TS11 (or a TU80 -- same thing
actually). I can't seem to actually located one.
I've created a unix v7m distribution tape and I want to see if I can't
install from it.
Thanks.
