Well.. if you're going to go QBUS LSI - why not go all the way and
get a usable machine!? forget a low end 11/23 with only 128Kw
of ram and for for an 11/73 (or the like) 4 megs ram.  a nice small
enclosure,
can use RQD series controllers and MFM (yuck) drives, KDA50 and  DSSI, or
better yet SCSI disks. You can get a DELQA ether card, a serial mux
and you'll have a modernish unix with TCP/IP & a real PDP11 underneath,
without it taking 3KWatts to to run or weigh a ton! ... within your 1K
budget!
A good place to start might be to pick up a MVII and decserver500 (11/53)
Else, a good  blinkenlights machine will run you between $600-1200 without
much disk...
