Thanks! And apologies for posting in the wrong group. Should have been HW and SW hacking. Inexplicably I was drawn towards Escape Meta Alt Control Shift.

Re: 1-byte NOP for vCPU
farjump.txt When coding in vCPU assembly I spend a lot of time on relocating code because of pagebreaks, and I was thinking of ways to avoid this headache. I added 7 far jump instructions, written as assembler macros: JMP address (far jump always), JMPcc address (far jump on condition, where cc = E...

Langton's Ant
Here's a small screensaver program that I wrote in vCPU assembly to get my feet wet on the Gigatron. The ant's direction vector (Left or Right turn for each state ) is generated randomly. Up and down arrow keys let you cycle through the number of states (from 0 to 63), left arrow restarts the ant wi...

Hello all, A new Gigatron is online. I learned about Gigatron (through my youtube feed) on Thursday and had to order the kit right away. It arrived on Saturday, I built it on Sunday and to my delight it worked right away. In my book, that's a testament to the quality of the design. Rummaging through...
