- It depends, this other write thru logic chip may be the answer... Power cart

- Yes, this I knew! (You crossed out my ;) )...

- Wouldn't it be cool to make a 64 with symmetric 65c816's (about 10-20) and
- add a geometry engine cartridge (Transputers) and make the first Commodore64
- that is an 8-bit reality engine? I think we are nearly there!
