Very useful. Thanks!
After the development of Thrust, I had a few people reporting problems
which are related to PF writes (especially Gemini and some 7800, but).
It turned out, that they are slightly slower than a original 2600.
Instead of 2/3 cycles, they delay by 1 whole cycle.
Maybe someone with such hardware can make some tests.
Have fun!
Thomas
