The CPU board is up and running, EhBasic works properly and both VIA's can be accessed correctly with peek and poke commands. The interrupt system also seem to be working as expected. If I enable interrupts from the ACIA they are received and can be processed properly. I have no reason to think that the VIA interrupts would not work. I did change to a 65C02 processor in order to not have to rewrite the monitor software. Oh well, it seem to work properly as well.
Next thing on schedule for my computer system is a graphic controller for gaming and visual presentation. This will be done with an FPGA system to allow for some fancy layering and sprite capabilities.
Stay Tuned.........
