COSMAC VIP (RCA 1802) first try at low level coding with some HAKMEM 149 1-bit drawings (128x64), ~134 bytes program, some of it taken by the high res mode setup.

Also wrote a #cosmacvip (and related) low-level coding quick start article : https://www.onirom.fr/wiki/codegolf/cosmac_vip/

A fun computer for its simplicity and extensions / variants, Chip-8 (or Forth ?) may be cool to experiment with as well. (1802 is kinda unusual !)

The program runs fairly quickly in the emu.
