Hello Ruud, >> But one question. Since it works as a simple Ultimax mode ROM >> cart what is the purpose of the RAM? >The VC-10 need at least 40*25 = ~1KB space for the >screen, then 256 bytes >zeropage and 256 bytes stack. Means only 512 bytes are >left. Not much IMHO? >So that's why the extra 2 KB are needed. >That VC-10 shows that only 2 KB are free could mean Is this true? I thought the Ultimax had 4k built in? Hence after a normal boot it would fill the 1st 1k with ZP, Stack, system, and the next 1k with screen, leaving 2k.
