Re: Which EPROM box to use with two equal length EPROMS Message #2 Posted by Diego Diaz on 25 Apr 2008, 9:33 p.m., in response to message #1 by PeterP
Hi,
2716, and 2732 are both 24 pins, while 2764, 27128 and 27256 are all 28 pins. I can't think of ROM images by those days burnt into bigger EPROMS.
In any case, if you're going to plug a 24 pins EPROM into a 28 pins socket, just remember you *must* align it to the bottom pins, thus EPROM's pin 1 will connect to socket pin 3.
