These come up on eBay every so often, but they are untested or I miss them. Does anyone have any spares of this old chip? I've got an old Apple II that I'd like to use the regular keyboard instead of a PS/2 adapter. I purchased some of the "C" variant (MM5740AA/C) some time back, but they have a different key mapping than the Apple computers. If someone needs those I can post for free or trade. I have no idea what keyboard they were used in. I have an MM5740AAC/N which I used to keep an industrial control working. It hasn't been turned on in 13 years, but ought to still be good. The key codes are in the data sheets, which ought to still be searchable online. I made an adaptor board that plugs into the MM5740 socket and recodes for the funny char sequence that that particular machine used. It uses a 2732 as the code translator. Jon
