Jump-less Dual-Kernal Switcher: Revision history

• curprev 22:2522:25, 23 September 2026 Josh talk contribs 7,502 bytes +1,778 Rewrite from BWACK's own SKS64 README: the switching sequence is hold-and-tap RESTORE with an RGB colour code, not a double reset tap; MCU is ATtiny45/85 not ATtiny13A; it does need RESTORE/RESET/EXROM wired into motherboard vias; the short board loses a bank to BASIC because U4 is a combined 23128; add the drive-switching feature, the EXROM cold start and the CERN OHL v1.2 licence undo
