Dalders Posted June 6, 2021 Share Posted June 6, 2021 Hi, i have a coco 2 with does not have extended BASIC. It only has a single ROM, so i have purchased a 27c128 chip to put both BASIC and extended BASIC on, but how do i put two roms on the one chip? I tried concatenating basic and extended basic 8k files into one file, but that didnt work. Can anyone help? Quote Link to comment Share on other sites More sharing options...
MrDave Posted June 7, 2021 Share Posted June 7, 2021 You need to burn exteded basic on the first half and regular color badic on the second half 1 Quote Link to comment Share on other sites More sharing options...
MrDave Posted June 7, 2021 Share Posted June 7, 2021 So first load extended basic onto the rom... then load basic with offset 2000 The coco maps it to 8000 h and A000 h Good luck Quote Link to comment Share on other sites More sharing options...
