Help!!! I need to change my Mega so I can use 256k Eproms. I now have 1meg roms, but the sockets are there for 256k roms. I can see that the jumpers in W3 and W4 need to be changed, but what else? I've been a tech for the last 20 years, so a quick list of what to do is all I need. Hurry because these new Eproms are burning a hole in the static foam. Just reply to the message. Thanks, Al Palmer

I also find it interesting that listed in the Mega schematics, one can see that it is (electrically) possible to put six 1 meg ROMs in. Will this map correctly into the ST's memory map? --Dean
