If I understand it well, I could use one tabletop TK50-GA I have :-)
That's right ?
Oh, another more thing: Could I take one complete image of one
backup tape to put it in a "virtual tape image" format ?
I have one backup of Oracle for VMS (very old) and I'd like to recover
it and mount under one simulator like SIMH or so.

Boot-up choice is made by telling the system which disk to boot
from. But you don't get to that choice unless you modify the boot PROM (I
think not EPROM) to account for the V20's faster (fewer cycles) execution
of a timing loop. The modification is documented, I think it's in Rainbow
News and I can dig it out in a couple weeks if anyone is interested.
For purposes of the original thread, modifying a Rainbow is
needless, because it already includes a Z-80 (4 MHz) in addition to the
8088 (4.mumble MHz), and will run Dec CP/M-80/86. It probably makes a
pretty good platform for anyone wishing to cross-develop from MS-DOS (up to
3.10b) to CP/M.
For hot-rodding purposes, the V-20 mod is recommended by Rainbow
News as a good way to get more speed out of the Rainbow.

but it won't help with the current distribution problem. The PSU
who's output after the diode drop is the highest voltage will end
up sourcing all the current. Not what you really want.
-tony
Not quite, the forward volt drop of the diodes will even
out the current between the individual units. Even
shottky barrier diodes have a vf of >0.4v at the curents
that would be involved.

Has anyone ever gotten a "TK50-Z" in a 'TK SCSI' encosure to work with any
'normal' scsi controller on a PC or something? I picked one up for a few
$$ today, and just realized the enclosure has a 220V power supply...
Also, how do I get the disk out of an RRD40 without a computer attached?
If anyone's interested in this stuff, reply off-list:
DEC RRD40. I don't have anything but the drive and whatever is stuck in
the drive with the CD in it. In a 110V external enclosure.

Well, I just acquired a 5' x 3' x 2' IBM AS400 drive cabinet. F--n
heavy!
Now, to mount equipment in it, I need to find some more of those
clip-on T-nut kinda things, which clip on around the hole in the rails, so
you then use the supplies screws to mount your equipment. Some older DEC
racks used the same thing.
And, as you can guess, the guys at the local Home Depot just gave
me funny looks.
Anybody know where I can get a dozen or two of these screw mount
sets? For a reasonable price? And what are they called?

I recently acquired an HP 13215A PS (power supply for a 7900A Disk

an entire system and sold it for scrap piecewise). I can see that one
of the terminal strips is labled with the output voltages (I assume) but
other than that, I have no idea what this unit provides or requires. I
would like to use this PS to power a FC array I have, but I don't know how
to energize the PS, nor do I know the current ratings.

It would also help explain why I've got 2 DELQA's without cab kits, and an
extra DEQNA Cab Kit.
On a positive note, the VAXstation II/RC I stole the DEQNA from needs a
DELQA if I ever get it running and the PDP-11/23+ can make do with a DEQNA.

Will BOCHS run on that version of windows? You may have a chance with

This machine used to at least power up without
exploding at least two owner's ago. It seems to
be the same machine reported as having a 2.5V
REGFAIL about four years ago ... so it's not
been powered off for a *really* log time.
OTOH, the PSU blocks do need to be plugged
back in correctly otherwise something

I'll go read the printset as soon as I dig it

And once the first one drops dead, the next
most "powerful" one repeats the process.
Proof by "induction" left as an exercise :-)

Guys,
Anyone have any luck running OS/2 under an emulator on Windows 2000?
Just wondering. I tried installing OS/2 Warp 3 on my copy of VMWare 3, and
it (VMWare) got mad and won't allow it to install. The web site says VMWare
will not (and has no intention of) support OS/2.
I was hoping to find a way to run trusty OS/2 on my laptop when I wasn't
busy with work......
Thanks!

I assumed he was asking for free system software to use with it
since he for some reason couldn't get the original installation of
windows to work. Hence my original answer, but you're right, it's

Some however will be oxides and van be very conductive.

RE: 2114s
Over the years i'd seen A higher than normal {2102 as comparison}
failure rate. So I had the opportunity to do some checking on why.
NOTE: the 2114 never had as good a failure rate as say 2102 or
other 1k designs and the next generation of 16k static parts were
substantially different with better failure rates.
2114s common failures:
Delayed stress damage due to ESD. Common failures are address
inputs.
Missing bit, usually a failed output due to either ESD or excessive
IO loading.
bond failures (works when hot or cold) most of those are plastic cases
and likely due to cleaners causing internal plastics to expand and lift
a bond {usually during board production}. Other likely causes, heat!
Ceramic devices seems and generally were more reliable.
The CMOS versions 6114 (nec D444) were more relaible, though ESD
induced stress failures were a major factor.
In the early 80s it was not uncommon to visit a site and NOT see proper
ESD protocal used when handeling MOS or CMOS devices. In most
cases getting the production people using would often see a substantial
drop in early failures{infant mortality}.
