Subject: Solidisc RAM/ROM
My BEEB has for many years contained
the Solidisc TwoMeg 128K board.This
comes with a Manager ROM image which
enables the use of Shadow screen
memory.
This all works perfectly, provided you
use the Solidisc DFS ROM and Manager.
If you try to use the Acorn DFS
(necessary if you want to run any
protected disc from e.g. Superior
Software), there are problems. Most
protected discs require a SHIFT/BREAK
boot up. This causes the computer to
lock up solid.Only a CTRL/BREAK will
clear it.
Hence, I can use Solidisc Manager +
DFS, or I can use Acorn DFS but remove
the Manager and lose Shadow memory
use.
The problem obviously lies with the
Manager ROM image. Does anybody have a
solution which prevents it interfering
with the DFS ? It would be simple
enough to edit the Manager code and
save the modified ROM image, if only
one knew which bit is causing the
trouble. I assume the whole thing is a
deep and dark plot to force people to
use Solidisc's own DFS !
Personally I like the Solidisc
products, but Superior Software in
particular obviously did not.

I have recently got a 6502
co-processor (issue 2) for my Master
128. I have worked out how to plug it
in to the mother board, but am now
stuck. It appears to do nothing, is it
not working? Do I need a controller
ROM? All help would be appreciated
