Possible to wire a 32KB ROM for the 5200's cartridge?

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!

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

Considering both of my 5200 homebrews used a 32K Eprom, I'd say yes.

Found the schematic.
