Williams (Joust, Robotron, etc) bank switching w/Fluke
I'm trying to switch the rom in at 0x0 so, based on info I found on the net, I write a 1 to C900.
However, any subsequent read is coming from RAM (confirmed by writing a value and reading it back).
I haven't looked at the watchdog circuit yet to see if that might reset the hardware that does bank selecting ?
Has anyone here done this ?
