I have a couple of ROM/RAM boards, but I have yet to finish building them. Right now, I'm short on 20/40-pin headers. > As for the possible > dead CHARGEN ROM in the other board I believe that a 2532 EPROM's can be > used as a replacement for the 2316b...is this true? if so I have a few of > these EPROMs hanging around and can easily burn one with the appropriate ROM > file. I'd recommend using a 2732 - they are much more common (I can probably burn one for you and toss it in). 2532s are perfect for replacement masked-programmed ROM replacements in newer PETs (post-6540s) or for adding user-contributed firmware into the "open" blocks on dynamic PETs. My old 2001-32N always had a full suite of enhancements (12K, loaded as 4K, 4K, 2K and 2K - for various utilities). I forget the minor difference between a 2532 and a 2732, but you can *not* drop a 2732 into a regular ROM socket - perhaps you can for a Char ROM, though. They are so close that a quick inspection of the footprint differences should suffice to reveal what's unique. -ethan Message was sent through the cbm-hackers mailing listReceived on 2010-01-21 17:00:43
