Ah, will  the 11/73 work in the H-11?

The answer is "Maybe." It depends on  whether the H11 does anything
"funky" with the -- at the time of the  LSI-11/03 -- unused bus lines
that the 11/23 and 11/73 (and later 22-bit  '11 CPUs) used for the
higher order address bits.

It shouldn't since  the H11 uses the actual straight from DEC LSI-11 CPU 
board.


You  will probably also want to invest in an MSV11-L RAM; or if you
feel very  bored, wirewrap the backplane to 22-bit and invest in a 512K
or 1MB RAM  board.


Otherwise, it should be  fine.


Cheers,
Christian
