Hi,
Got an old Apple //e which keyboard ROM seems have some problem, it's an 2716 ROM but it's now obsolete, don't want to buy the Chinese old one, as they maybe fake or fail soon. Remember see some post that can replace with 27C256 (which I have an ATMEL OTP), but how to do this? Seems need an adapter or some pins modified, please advise.
Thanks in advance.
Rgds,
Johnson.
