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.

When I rebuild the PZ1 HW, the SW has to wait for later. This was not ideal, so yesterday I built a second PZ1 that has only a Teensy and a 65C02 connected on a bread board. This platform is perfect for testing new 65C02 code, and also to test new HW ideas in a simulated environment.

Today I wrote a lot of code to test and document the instruction timings of the 65C02. Available documents disagree on many of the timings, and/or are very hard to decipher.

Now, if I could only find how to enclose the document...
