Beginnings of a virtual 6502 mode for Gigatron

Marcel of the Gigatron TTL Computer Project has announced a work-in-progress 6502 emulator, “v6502”, residing in ROM. (This complements the existing virtual machine: one is not expected to program the Gigatron at machine level, although it’s possible.)

That’s a neat hack!
Fun stuff.

I decided to add the flashing @-cursor, map delete to rubout and all keys to uppercase. Much more authentic :slight_smile: . Interestingly, I could restore more of the original wozmon bytes along the way.
