Hi, I am looking for some assistance, I recently picked up a Franklin Ace 500 (Apple IIc clone from the 1980's). It has a damaged keyboard. From what I can tell, it has the Futaba MA-41 clicky keys (not the cherry variant). I was able to remove one of the damaged ones and cut it open and from what I can tell the little rubber mat inside of it melted. I have about 20-30 of them damaged/non-functional. I am looking to see if there is a source to replace them, possibly repair them or if there if are other types of switches that could replace them. Any help would be appreciated.
Thanks for any help
