Does the community have the actual PLA terms as source for the various devices or are they all/mostly reverse engineered? -----Original Message----- From: email@example.com [mailto:firstname.lastname@example.org] On Behalf Of Michal Pleban Sent: Tuesday, June 05, 2012 2:45 AM To: email@example.com Subject: Re: 6502/6510 ROM selection daughterboard Hello! firstname.lastname@example.org wrote: > I don't see this as a deal breaker type of problem.

Well, if we decide to go this route, I don't see any problems in doing this type of extension. I can do it, actually. Plus, the character ROM replacement can then be done simply by un-socketing the CHAR ROM chip, and placing a single wire from the CS# line to the CPU extension board (assuming the CHAR ROM is socketed too). > Could you maybe publish it? On zimmers for example? Yes. I designed a PLA replacement circuit, and I intend to read and decode every PLA that comes into my hands :-) I am missing only the 8296 now, plus waiting for the 1551 to arrive from Ebay.de. When I have all the stuff ready, I will publish it. Regards, Michau.
