What we need now is a shifter which can make use of the extra bandwidth ;)
Nice - Once this final STF Remake is realised its going to be quite some machine.

Indeed.. If we all still alive by then :lol:

The mongral will be a huge step forward. Then all the mongrel fixes can go on the next board where hopefully we will have more FPGA cores running.

And with an FPGA and tweak to TOS, any resolution you like, as long as you have enough RAM.
If it ain't broke, test it to Destruction.

I would assume EMUTOS already has options for extra video modes.

So I have a piece of software that will make that videomode actually produce a workable desktop ... :)

Hi troed - Am interested in the software you have. I have read outposts around the extra modes and its very interesting.

16MHz vs Falcon.

The int-div is a lot slower on the 68000 over the optimized 030.

EDIT:

I don't remember if the Falcon benchmark was with or without the waitstates on ROM...

Yeah, int-div probably work out about the same as the 030 CPU when the 68000 is running 50MHz.
