   Yes, the 725/730 is limited to 5Mb, although it's tricky to find enough
 slots for this if you've got any peripherals.  I have a 11/730 that's
 fortunate to also have the BA11-K UNIBUS expander box, so I've got room for
 5Mb, but that was an unusual configuration.

   The memory boards used in the 730 are the same as the 11/750 1Mb memory
 boards. 
Fun. I didn't know the 11/730 used the same memory bus.
The 11/750 and PDP-11/70 MK-11 box uses the same memory bus, but 
unfortunately the MK-11 don't support any larger arrays than 256 KB 
memory boards.
