CoCo 3 related information you can find in:https://colorcomputerarchive.com/repo/Documents/Books/Unravelled%20Series/super-extended-basic-unravelled.pdfpage 57Looks like the image starts at address $C405 in memory.  Now since this isbased on the ROM starting at $8000The math which would be $C405-$8000 should come to $4405 in the ROM dumpfile.  If that is correct.Hope that helps.Sincerely,David Ladd***END OF LINE***On Fri, Apr 5, 2024 at 11:58 AM coco--- via Coco <coco at maltedmedia.com>wrote:>> I would like to know where The "Three Mugateers" Image is located in the> in Coco 3 Motherboard ROM.> As well as at what addresses the code that handles the Hard Reset that> displays this picture is located.>> I was thinking that if you have a CoCo 3 with a socketed CPU as many do> thanks to the 6309 a board could be built> that masks out that portion of the Motherboard ROM, rather then just> putting a picture there there could be code> to allow custom code on flash memory to ran instead.
