Someone I know has just acquired a motherboard, XT type aftermarket,
with 768k onboard ram. I'm fairly sure the system is going to need a
special driver to access the memory over DOS's 640k. Anyone have such an
animal and can attach it to email or know of a commercial program that
will handle the job?

Well, I got bored tonight and pulled out a DECserver 200/MC that somehow
ended up with many months ago. First thing was take a scredriver to it
(it was quite noisy and I figured I should probably figure out what the
obstruction was). Well, the obstruction was, well, dust. Although I'm
not writing this message to talk solely about dust, this was some
interesting stuff. From the looks of it either this thing had been
in/near a fire or it's administrator smoked at an unhealthy rate. Very
black and very plentiful. Also very difficult to remove (extremely fine).
Removing most of it made it quieter.
Anyway, what can I do with this thing? I don't have the boot images for
VMS, nor do I currently have a running VMS machine.
When I turn it on, the D1 light turns on, followed shortly by the D2
light, and the D3 flashes when it's transmiting. And there's MOP packets
on the ether, so I must assume it's in working order. Eventually, the D3
light starts flashing constantly and D4 starts flashing every half-minute
or so.
I don't suppose there's any way to do IP, is there? One thing I was
suprised to see in there was the face of a big original package 68k. It
might be interesting to write a custom boot image. :)
In any case, does anyone have a copy of the boot image for when I get a
VMS machine back to being functional again?

Spam is bad. Spam is theft of service. Spam wastes resources. Don't spam, period.
I am a WASHINGTON STATE resident. Spam charged $500.00 per incident per Chapter 19 RCW.
I thought I'd put out a warning about the Teac FD-55BV-16-U 5.25" floppy
drives. They seem to be totally unsuited for anything other than reading
MS-DOS floppies.
I bought one a couple months ago, for a project with my Amiga, since they
were what the developers of the Catweasel board recommended. Spent about
two days trying to get it to work. Finally I pulled the drive out of my
486 (an older Teac drive) and it worked immediatly. Assuming the Amiga
part of the equation was the problem I put the new drive in the 486.
Well, yesterday I needed to make archival images of some RX50's. No dice,
it absolutly would not read them. I'd picked up some older Teac's at the
last swap meet, so I got them out, and after two that only semi worked I
found one that works just fine, and was able to make my images, copy them
back to new floppies, and boot my PDP-11/73 off of them.
Note, I tried using the Teac FD-55BV-16-U drive with both 'putr' and
'teledisk'. Neather would work with it.

Can you trace the circuit of the buffer chip to see at least what pins are
outputs to the 2716 (addresses) and what is from the 2716 to the adapter
(data lines)?
Another choice is a '125. A '242, '243 only have the data inverted from each
other, so if one's the correct chip, the other won't cause logic conflicts,
just wrong polarity signals.

Well, thanks to the answers I got on my questions I've got a bit better of
an idea on how to proceed with getting the newly built from parts /23 up
and running, and I understand why I was having difficulties (as I thought,
the path through the backplane).
Since I'm using a RQDX3 for the drive controller, it sounds like my best
bet is to forget the RX50, and go straight to RX33 drives. However, based
on my taking an additional look at the RX50 drives I'll probably try to get
them up and running. What can I say, they're just too cool looking :^)
The QD614 board for emulating RL01/02's sounds pretty cool, to bad I don't
have the software for formating the attached drives.
