This is an emulator for the Ferranti Pegasus Valve computer from the 1950's There are existing emulators, but they have a number of issues:-
1. DOS based and don't run on 64-bit Windows without use of DOSBOX

3. "Closed Source" so they can't be modified.
This emulator is designed to overcome those issues.
