G8PP Baseline Configuration
G8PPBase+6502
Serial Bootstrap, move jumper to 'Serial Bootstrap' position, load Tinyload.bin as binary file (check the 'Binary' box in TeraTerm), Tinyload will sign on with '12/26/18'
6502 Monitor
EhBASIC by Lee Davison, load 'MIN_MON.HEX' as hex file (do not check the 'Binary' box in TeraTerm), type 'G e82a' after load is completed. EhBasic will respond with '6502 EhBASIC [C]old/[W]arm ?'
ASCIIART benchmark for EhBasic.
