A little like suggesting building a Stradivarius is as simple as finding
Mr. Stradivarius' CAD drawings and running it through a 3-D printer.

Pete, this is a Commodore 64 and the source code is certainly 6502 Assembly
directly bit-banging on the C64-specific peripherals.

The fact that Dr DX achieved so much using stone knives and bear skins as
the base technology makes it a more impressive marvel than a Stradivarius
:-)

Rich's original post where he mentions the possibility of a C64 emulator
seems very promising. The paddle/keying would have to be a custom I/O mod
to the C64 emulator but many are modular enough to add simple peripherals
like this.

C64's are quite commonly available used and the ROM dump Rich identified
may allow a new cartridge to be burned. Presumably the paddle/keying is
done the simplest way possible.
