unebonnevie Posted February 12, 2017 Share Posted February 12, 2017 Hi, I have seen the 5200's schematics of wiring two 16KB ROMs for the cartridge. Just wondering if possible just to use a single 32KB ROM. Thanks! Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 12, 2017 Share Posted February 12, 2017 From what I can see there would be some rejigging required... the cart connector provides 2 active low /CS outputs, one for low, one for high part of the address space. For a single Rom I should think what's needed: . AND the two /CS together to provide a single /CS for a 32K Rom. . /CSL could be used on it's own to provide A14 Quote Link to comment Share on other sites More sharing options...
+Cafeman Posted February 12, 2017 Share Posted February 12, 2017 Considering both of my 5200 homebrews used a 32K Eprom, I'd say yes. Quote Link to comment Share on other sites More sharing options...
