I contacted the seller, he is relisting in a few days, I might go for
one of them. 

Any tips on getting rom images to the beeb, I used xfer many years back
right from the beta release but from what I remember only usefull for
files with the .inf description included - roms would be transfered as
text ....not good.

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.

Mark.
