They are not very common, four slots were a tight fit to make a 
useable system.  I have a one with a bad PS that I'm saving for 
repair parts for the good one.

The one ugly fact was with all four slots filled with RAM and DLV11j
plus CPU that meant every boot required entering by hand the TUboot.

The alternate was CPU, two MXV11 one with TUboot rom.

The nicest configuration is a BA23 deskside case as then you can put
in a RQDX2/3 and have a floppy and a small (30mb) hard disk easily.
