Bardzo sprytne rzeczywiście, Spidi!
My friend a very clever method using the CIA as a flash controller - quite insightful, a simple modification could see this product of yours also available for the A600/A1200 with only a little modification - in fact you could probably use the current Flash Board "as is" on the A600 with a different CIA adaptor (re 44pin PLCC socket) on U8
Very clever indeed, one could expand on this for the A1200 version again using the U8 CIA clip on designed for the A600 =)
This is a great project and one I look forward to getting =)
By the way, Tak, Polskie to piękny język!
