The Cactus is a *new* computer with 6502 CPU, OSI BASIC ROM and working front panel. WOW! I guess you could call this the prototype model, we hope someday to see this machine in kit form for hobbyists to assemble. The only other 6502 CPU with a front panel that I know of is the CGRS, made as an add-on interface for the SYM-1. Click image for larger view.
