Nice! The blitting power is insane!

I took a screenshot vs the 50MHz booster (the benchmarks were TOS206 which gives different results) but the video is TOS104 to match your machine...

I find this interesting because, trashing the CPU & ROM at 50MHz about manages to beat a true 16MHz system on some test (on GEM stuff that is) , despite the 50MHz has a 8MHz RAM bottleneck...

Theoretically, those 50MHz results should basically double in speed when combined with a 16MHz bus.

Wow, blink and you'll miss the blitter test.

Thought I would post a few images of the desktop as I was working my way through this patch. For each step turning the power on to see how it was reacting to the changes was interesting.

640x200x16 ;)

What we need now is a shifter which can make use of the extra bandwidth ;)
