Pentagon-II
ZXNet echo conference «real.speccy»
Good afternoon.
Many thanks to everyone who sent the ROM image for the Pentagon. After replacing the ROM
and processor it started up,
but does not turn on TR-DOS. An attempt to get there from the start menu
results in a reboot, the command
RANDOMIZE USR 15616 also leads to a reboot.
Where to dig? Change ROM firmware? Something died in the address decoder
of the controller or somewhere else?

The reasons may be different, and the ROM may also be to blame.
Just check A15 on the ROM first.
