Second scanline disable for double the performance:
Disabling scanlines on the Gigatron is not just a retro feature, it's also a method to allow the vCPU interpreter and SYS function calls access to more CPU cycles. From my initial testing disabling one extra scan line allows for 100% more vCPU and SYS cycles, (i.e. double the speed as tested by Mand...

Re: Extending the Gigatron instruction set
This is interesting stuff, obviously as hackers we can do whatever we like to our own individual board's instruction sets; but there is merit in discussing the idea of modified/enhanced/additional instructions to future ROM upgrades as well, (IMHO). ** removed the junk about vCPU code ** There's lot...
