One of the few problems with the ST is it's inability to
display all three graphics modes on a normal monitor or TV. The
High resolution monochrome display usually needs a special
monitor. Some software, such as 'Signum' and 'PCB Designer' only
works in monochrome mode, so if you do not a have the monitor then
you can not use the software. This small program provides a
solution to this. The Mono Emulator make the ST run in mono mode,
but provide a picture which is suitable for a normal monitor or
TV.
