Expansion port switching
Hi, I am looking for 100% function switcher of C64 expansion port -> which pins at the port I must switch for changing between Action Replay, Final Cart., IDE64 etc. ?
Some old switchers for exp. port are not function and the switcher by CMD I have not tested...
Can you help me? Thanks,
LHS
P.S. I am sorry for my lame english :o)

Try this page for some hints: http://markus.brenner.de/cartridge/index.html
It should be possible to just have a /GAME and /EXROM switch for each cart. Data and Adress lines should not affect the other devices as long as the correct cart is "on". This is just my first idea and it could be completly wrong too. |

and of course I was wrong.. :)
You probably should have a switch for /ROML and /ROMH too. Might even need one for /"CR/W", /IRQ, /NMI and /DMA. |
