< The only thing on the board is what's on the handle; "M8186". There is
< circular sticker on the underside of one handle that says "mpg jun/81"
< it. There are four 40-pin sockets (individual pin sockets on the board)
< with the following configuration:
<
< 1) AMI 303D & AMI 302F on 8048 DEC
< 2) AMI 303D & AMI 303D on 8117 DEC
< 3) Empty
< 4) AMI 304E

What's th3 point it's a m8186 kdf-11, aka 11/23? the only thing I can add
about it is it appears to have the FIS (floating point extended
instruction set)

that should run most anything in the way of DEC OSs with the only
question being is it limited to 18bit or 22bit able. The latter being
less of an issue unless your using more than 256k of ram or certaion
backplanes/periperals.

< One of my problems is that 4 8" drives are my only storage devices. Any

RT-11 was nominally supplied on rx01 (8" single density) or rx02 (8"
double density) floppies. RSX-11 wants a hard disk for swapping and all.

< As far as the Multifunction board, I checked the pins of the console
< port with a scope but I can't seem to get anything from it at boot. I
< checked the scope on another serial output source and it seems to be
< working OK, so I'm assuming that the port on the PDP just isn't giving m

1 which port there are two?
2 is one of the ports set up as a console?
3 is the rom on the MXV setup for the correct boot and is the rom
  installed?
4 can you hit break and get console ODT prompt and actions?

There is a good possibility you have a improperly configured MXV-11
and there is a sea of jumpers on it and it must have the correct proms
installed as well.

< any console messages immediately on power up? Does it display the POST
< procedure, like my Vaxstation? One Sun 3/50 I had with 12 megs of ram to

No! The BDV11 if you had it does.

< around a minute to display a console message; should there be a long del
< like that when booting a PDP-11?

If there is a few hundred K maybe 10-20 sec. usually you hear some disk
activity before that and then it boots.

You vax and Sun knowledge is not helping you as this isn't them.
