I really do have other things on my mind, or i'd still be using it. And
prolly not be online yet.

It would for me too, i didn't do any garbage collection in the kernal. I did
have code that basically ( pun intended ) wrote out the low memory vars to a
upper area, pulled the high mem vars down, thereby compacting them, and then
pulled the ones i temporarily stored in upper memory down on top of those.
It was slow as cold honey, but it was a 1Mhz 8bit cpu. The block moves were
faster, so writing out zero page and the app and a small slice of memory was
easy and fast, making it worthwhile to do time-slice multitasking on the C64
easy. As was mapping the VIC chip to make windows that were more stable and
faster than mswin1.0 on a 286. Even with word wrapping in those windows.
Maybe i should try to make the system operateable again,, i'm getting
nostagic. Heh, i remembered the reliability of the CBM floppies, nevermind.
As for learning things, you can get the source code to several compilers
online, isn't the compiler that comes with some linux open source? What
about the GNUPascal, and other GNU code?
