Well... using my incredibly average Excel powers, I created a big sheet that, once I plug in the byte figures from hand-tokenizing programs written in the language I'm desiging (tentatively known as Yanushka but that's only because he's the Calculus II professor in whose class I've been doing most of the design work-- it will most assuredly not be the name of the finished product) keeps a running tally of how many bytes the program is taking up, how many this leaves free on the 2600 and 7800, how many bytes this leaves assuming the kernel takes up 56 bytes on the 2600 (which I would say isn't a bad estimate) and assuming for some reason only 1kb is available for program storage on the 7800. When the space in RAM runs out on the 2600, the feasibility of that project drops from 1 to 0. Same for 7800. In any terms, basic tests using this worksheet using any program of a non-trivial nature (over ten lines in pseudocode length) show that this almost definitely isn't going to work on a 2600. I guess the 7800 is calling my name-- I've been wanting to learn to program it anyway.
