Soft irq

A project log for PZ1 6502 laptop

I am building a laptop with a W65C02, lots of memory, SID-sound, decent graphics and a filesystem.

I just added the possibility to change irq-rate by writing to a 16-bit register in the PZ1. The irq used to be hard-coded @50Hz, coinciding with the frame counter, but those are now separated. This also leads to the possibility to change play-back rate of SID-songs with a simple DOKE in basic, very handy :)
