Is it okay for the chap to peel back the sticker and expose the EPROM like that to daylight? Doesn't that erase them?


Back in the 80's as a test I set an 8k eprom in direct sunlight everyday to see how much it could take. If I recall correctly it took about 5 days before it failed a checksum test. Different eproms will have different sensitivities but I never meet one in all the years that complained about a few hours under room lighting. Just not enough UV there.

I've seen that type keyboard before but not on an Amiga. It would have been possible for some hardware hacker who knew what they were doing to take a standard cherry and mod their own Amiga version. I used to hack eprom code on keyboards and clone pc's back in the day. Wonder if it was some limited third party replacement product.
