I suppose that once you've got a 6502 working, adding support for a 4510
shouldn't be too difficult....

Well, the stack pointer be a single byte, so pushing things on there doesn't work terribly well.
Assuming I pass by reference, that's 128 values absolutely total before it wraps around and silently clobbers itself. It means single byte values will be incredibly inefficient... Tricky stuff.
I'm lucky on the C64 since it's rare to exit back to the kernel with machine language apps
