Re: Fluke and space invaders input ports

Well how do you do it?

i thought i'd answer on-list :) hit READ, select the ADDR OPTION to I/O then read address 1 repeat for addresses 2 and 3 for the other input ports.. I didn't check them out fully, however, address 1 is for player 1 controls and coin/start for sure. Port 2 has the tilt switch. I didn't bother with the rest as the main things i was looking for were stuck switches, of which there are none on this troublesome pcb :( the read result has to broken into its 8 bits, if you read the address, then hold the appropriate button and re-read, the result will change... its pure sorcery i tells ya!!

Thanks, Kev
