The Solidisk method was quite good, but it was a pity it
didn't work with the (later) standard Acorn *SRLOAD/SRSAVE
commands.

I got around this by modifying the Solidisk board slightly
so that four of the Ram banks used the Solidisk latching
method and the other four used the Acorn method.
I'm not sure if I've still got the board, or if it works.
Too much Beeb stuff around, which doesn't get used these
days.

Does anyone want any, who are in the Essex area, and can
collect?
