Hi, is there any way to switch between the 6F speed-up chip and the regular speed IC without having to manually swap them?
The specs (page 35 of TroubleShooting Guide Part 2 - http://www.arcade-museum.com/manuals-videogames/P/Pacman-Mspacman-Troubleshooting-Guide-Part2.pdf) say line 20 is a Chip Enable (CE) when low.
Does that mean I can wire all 24 pins of both ICs to the same traces on the PCB, then use a switch to toggle line 20 high/low on each IC?
thanks for any advice,
grimholtz
