Hi everybody.
Still working on those MIPS RISComputers. I've gotten all three to power-up
and self-test at least once.
The one that's giving me problems came to me marked "bad power supply." Not
being one to believe the markings, I tried it, and it powered up fine, did
the whole self test, and (due to the lack of any disks) just set there, as
you'd expect.
So here's the deal. I powered it off, and then back on. The second time,
it didn't seem to be getting any power at all -- not even fan-buzz.
Would I be right to suspect a loose joint or the like? Is there anything
else that might cause the power supply to work sporadically?
What's the best way to attack this and get the power-supply fixed? Should I
just dig out a multimeter and start checking connections?
Regards,
Chris

(Grumble).....
I'm getting conflicting information regarding the ability to boot the 4000
>from SCSI devices attached to the KFQSA SCSI adapter. Some people say you
can't do it, some say they actually have done it.
I have a DEC RRD-43AA CD-ROM drive, and have it connected to an external
SCSI box with a cable from it to the KFQSA adapter. Onboard the 4000 are
two DSSI drives.
The 4000 is able to recognize and assign device identifiers to the ethernet
port and the two DSSI drives, but has no clue ragarding anything attached
to the SCSI (KZQSA) card.
Is there anything I need to do with the "VMB" to make it recognize the
CD-ROM drive, or am I missing a step?
I'm attempting to boot the 4000 from the CD-ROM and start the VMS 6
installation process.
Thanks!
- Matt

I'm looking for detailed module specs for the vaxstation 4000, and
probably for the decstation 5000/1xx.
I have a pile of 32M modules that my supplier thought work in a vs4k,
but they don't. While I can't find any references to the labeling,
y'alls' best guess seems to be that they are ram for a decstation
5000/1xx. I'd like to find out if the difference is something that can
be modified, to make them compatible with the VAX. Failing that, if I
can verify that they really are DS modules, I can sell them.
The SIMMs themselves are from several different lots, but the
common label, which looks like a DEC/Compaq P/N to me, is 33522947-001.
Lastly, what's a 32M SIMM worth? I've got a little over $25 each in
these. If they're worth that, I'll convert or sell them, if not I'll
return them as misrepresented.

Actually, you can do either, and my PDP happens to have 5.25" disks in the
first place. :)

Best source for finding loose solder joints is to look at the board in
question...
I have a new rackmount slider kit for the IBM Netfinity 5100. This is the
kit that came with the unit so that you can rackmount it. The part number
on the box is 09N7484. It'll probably work with other cases in the 5x00
series.
Best offer by Jan. 2 gets it. Otherwise, it probably gets recycled.
Please reply privately (I know you will ;)

I don't know. :) Let me know if you find any. I have an 11/75 that would
love to run RSTS/E.

I thought that may be the case too, but one of the working units is missing
the tape drive (which this unit has...) and still functions properly.

This may be a dumb question but...
Will RSTS/E (specifically) RSTS/E-V7.0/07 run on a PDP 11/34?
