That's what I'm doing for my 2001-8.  I don't have enough working
6550s to run an 8K machine, so I have a single 62256 on a CPU socket
board strapped for 8K.  It would just take moving a jumper to go to
32K, but with original 6540 ROMs (the board can take a JEDEC EPROM but
I don't have one installed right now).
