As for the 8 SWR board, it's a nice idea, only things I would have designed
differently is
1) It takes up 2 ROM slots, so you can only have 2 ROMs in a standard
machine, unless you mod the free sockets for 27256/512s.
.......Or put it in the OS slot and piggy the OS, probably with Basic in a
27256 (a'la B+), leaving 8 SWRs and 4 free ROM slots with Basic already in
place - does anyone use a machine with Basic?
......Or, make it take up the length of the 4 slots, and put 2 27512
compatable slots on the board.
2) Why have the huge AA battery pack for a low power CMOS RAM? I'd have put
a small coin cell (or rechargable) on the main board.
