Hi , on the subject of [stella] [7800] I got a 7800 question...please don't flame me :), you said: > stack. Where is it? $100 - $13F is documented as being a shadow of page 0 > (TIA and MARIA) and $140 - $1FF seems to be used by the 6116 (RAM chip). > Does the 7800 have a full page for the stack? I'm no 7800 expert, but the 6502 line of processors and clones generally all use the $1xx page as the stack, and since the stack space should be mapped to some RAM, it looks like that requirement is fulfilled by the 6116 RAM at $140 to $1ff.
