OK, the first thing is this is probably a MOD 2 board being as it has a 74LS03 as IC24. The output is now on pin 11. Does it come out of RESET? On switch on it should stay LOW for about 1 second then go HIGH. Do you have the correct RAM fitted, it takes the smaller RAM (in Bytes) 256x4. HM6561 or equivalent. Because of this it won't run later games. T62 doesn't appear in this revision of the board as it has a thyristor (T56) in the RESET circuit.1 point

Classic 777 Heavens graphic layout will be released later this month. Forum member, Thompy, has been supplying me high quality images and technical assistance from his own machine over the last couple of years, just recently he has supplied vital lamp numbers so the emulation can be released with almost 100% accuracy. . 'Thompy' also supplied video and sound of the pull handle mechanism from his actual machine and thanks to our late, great, mfme author, Chris, it is now incorporated into mfme. J1 point
