always wondered how the uxn screen device worked, and after reading this i am feeling a lot more confident

i don't know why i originally dismissed writing a virtual machine in place of my usual sensibility of constructing a solution out of physical hardware--it may have had a little to do with jealousy, i was at first very startled by how clearly uxn communicates its ideas.

my thoughts right now are very jumbled, but i can imagine creating my own virtual computer as involving:

• instead of a screen device, have a nice bank of VRAM which is accessed via DMA--this i borrow from the hardware CHIP-8 machines. varvara is very nice in that it can draw 4 colours. right now i think i will merely focus on monochrome pixels.
• more system RAM than 64K, i will have to do some explorations on this
• a different instruction set architecture, i have some manuals on the xerox alto, stack machine ISAs, those of the lisp machines. i am quite besotted with BASIC right now, however, which has not much in common with the former. i wonder what a nice ISA could be...
