  I just paid about ?30 for some PDP11/03 boards,
CPU, MXV11 and some kind
 of serial card (can't remember the exact type).  I had a BA23 lying 
 around
 empty, and an RQDX3.  Now I need some media...

  Well what about a whole set  ?  A lot of people like myself can't be 
 mix-ing and matching
 part.  I just want to pen the  box and  plug it in if  I were to buy one.

 PS  A small HD would be nice too. I got a terminal already 
That is pretty much a whole set.  Oh, I didn't mention the two 
opto-isolated I/O cards I got from eBay too, they should be fun!

I got (from a bloke in Australia, just beating a chip collector) on eBay 
the following: M8047, M8043 and M7270.

The M7270 is a cpu, and the M8047 has some memory, bootstrap ROMs and 
two SLUs on board.  I could build a very nice portable RT-11 machine 
just with that!

Wonder what the current draw is?

Gordon. 
M7270 +5V at 1A    +12V at .22A
M8043 +5V at 1A    +12V at .25A  4 serial ports
M8027 +5V at 1.2A  +12V at .1A   2 serial ports, MXV11AC 32kb ram +Eprom

The M7270 is the LSI11/2 CPU (16bit address) and the MXV11 multifunction 
card are a near complete system on two cards. You would only need a Tu58
equiventlt on the secod serial port to boot or some disk (RXV21) to have
a system in three boards.
