Excellent job

Re: True 16MHz Mode
Very nice!! Looking forward to seeing the patches. Great work!! 
With all the enhancements the H1 should be a kick ass board..

And here it is in action - video of GEMBench running.
Re: True 16MHz Mode
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.

Very nice.. 
Re: True 16MHz Mode
Wow, blink and you'll miss the blitter test.
If it ain't broke, test it to Destruction.

Re: True 16MHz Mode
Looking forward to getting my 2 remake boards running this quick.
Re: True 16MHz Mode
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.

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