I'm thinking about designing a new static RAM

Would this be for the sake of a fun project, or would it be
practical necessity, such as need & availability of 1103's for repair?
I've got plenty of 1103As. I have two 9830A memory boards, one good
4KW and one bad 2KW. I haven't found time to diagnose the bad one. But
even if I fix that one, I'll only have 6KW. If I build my own RAM
board, with a couple of jumpers to one of the other boards to pick up
extra address lines, I can have 16KW.
OK, just asking as I have some NOS MIL 1103's in case it was need for such.
(MIL = Microsystems International Limited, not 'mil-spec'.)
I also would like to design a 9880A disk emulator for
it. That's more
work than designing a RAM board, but it doesn't look too daunting.
