Subject: Can anyone ID this Digital board?
recognized it as Digital. What did this come from? My best guess would
be a VaxStation, but I don't really know. I would like to get this
machine functional (I always wanted something I could run VMS on). Can
It looks like a lower-end VAXstation 3100. Compare it to the board in my
Infoserver 150VXT, which is a MicroVAX 3100 model 10:

Those machines have a single on-board SCSI channel (the wide connector
middle rear) but you need the proprietary cable to plug anything in. The
console connector is the one nearest the thin ethernet port and halt
switch - the four ports are labelled 0,1,3,2 with 2 being the DB25 full
modem socket.
Going from memory the 2 sockets furthest away from the back panel are for a
framebuffer card and extra memory and one of the back ones next to the SCSI
connector were for the 2nd SCSI card for external devices. Can't remember
what the other one was for, maybe a synch comms board?
Can't help with the power pinouts right now.....

Witchy's post reminded me of a question i've
had for a while now... how
feasable is it to covert a Microvax with a KA41-A CPU (as reported by the
Microvax firmware) to an Infoserver by just swapping ROMs (with an image
from Witchy?)?
It may work. The only way to be sure is to try it and see.

There is a way of booting the normal infoserver image on
a MicroVAX 3100. I just don't happen to remember it and
noone else has piped up with the details. It's pretty
simple, just set the boot flags to the correct magic
value and off you go. There was talk of removing this
ability from the software if word ever got out, but I
don't think that ever happened. I'm surprised that
noone has ever dug around and released this magic,
especially now that the Infoserver is no longer
sold.
Swapping the ROMs on a KA41 will almost certainly
be enough to make it work with no magic required.
I'm reasonably sure that the initial Infoserver
was basically a KA41-A with possibly some
unnecessary bits removed. They may even have used
culled chips (e.g. floating point not needed, so
don't reject those chips, just put them in the
InfoServer line ... it may even have been just
don't fit the separate FPU, I don't remember
how things were arranged in the CVAX days).

Tell me that now just as I've put my Infoserver back into the storage area
:o) Actually, you've just reminded me of a question I need to ask everyone
so I'll do it in a new topic.
