- I presume you're doing this with the blitter? does it run standard life at
- 50 fps? if so at what res....
- Thought about doing this myself for some time now, but instead i have been
- building a machine of my own (out of 74F/LS series chips only!) to calculate
- arbitrary 3x3 neighbourhood rules at 50fps on a 256x192 grid... It's now in
- the final stages of construction... seems like it's a bit small, but should
- be fun to watch when randomly seeded (which is where most other things fall
- down). Anyone want to hear more about it?
