I tried to use WDC65816 CPU (SuperCPU's CPU) opcode STP - Stop Processor to test if is possible to get work 8502 by software.
Not success - really it stops CPU and not handle anytime anything.
loop: inc $d020
jmp loop I had to work like you see: slow down to 1MHz, set 16-bit mode, set 8-bit AXY registers, increment VIC2E paper, stop CPU and I was experimenting if will continue 8502 (of course 8502's PC is there not) in loop incrementing VIC2E border.
Really if - when C128 starts (with SCPU) Z80 is initialized? And if get to work 8502? Or at turning on get control over all 65816?
Or better Q: How to initialize 8502 or Z80? It looks that STP opcode only send computer to death...
Any ideas are welcome...
Commodore 64 was great, Commodore 128 is bigger, better, faster and more powerful... Commodore 65 was almost here, now is back in Mega 65 and is more than ever was...
