A few PDP11 questions and FREE Cipher tape drive

Hello,

Before I continue with my Vax 3400, I want to get my PDP11 put together,
physically. I have a few things I would like to find, and a few
questions.

My 11 came with a 3 4-port serial cards. They are M8043 boards. I
can't see myself using that many serial ports. Does anybody have the
little blank steel plates to put in a BA23 chassis so I can remove the
plates that have the 4 db25 connectors?

Also, I need the plate that fits into the space below the serial ports.
It looks to be slightly larger than a centronics 50 SCSI connector.

Would anybody have the dip switch and jumper settings for a M8190-AE,
that's a KDJ11-B from a 73 or 83. My 11 was upgraded from a 53.

How about memory? If I use the memory that came with it, and do a "map"
it tells me the memory is parity. I bought a few surplus boards and one
appears to be ECC memory. I don't know anything about ECC, is it better
than parity? I have a 2-meg ECC board and 2.5 megs worth of parity
memory between 2 boards. One of my parity boards says "Mos RAM" What
is that? It is a M8067 LJ.

I am thinking that I would like to keep the chassis out of the tower.
Does anybody have a spare plastic bezel for a rackmount setup. I don't
have a rack, but it would take up less room if I keep the tower in
storage.

What to call this thing? It has the cpu board from an 11/83, but it
doesn't have the PMI memory of an 83. I would like to upgrade the
little square badge to reflect its current config.

Also, does anybody want a big Cipher tape drive? I also have a Emulex
TCO2 (I think that's it) to drive it, although I don't have the cables
to hook the two together. It would be free for the taking. I don't
think I want to ship it.
