Good to know - now the other question I'd have is if 60mhz tripled from 20mhz performs better than 50mhz doubled from 25mhz for graphically intensive applications (think Marathon), where (AFAIK) you get a benefit from the faster vampire video. That, or using an FPGA to build out a 68030 that can handle the 70mhz clock and sticking that in the accelerator (not sure if that's doable, though)

I had the same thought. I think 25mhz x2 to 50mhz would definitely be more well-rounded and also would have increased video bandwidth. However It would be a complete rewrite of the logic to work at 2x, I tinkered with it a little but didn't finish the job and have no plans to do so. I don't have much interest in the IIsi, nor has there been much interest in IIsi cards so I don't plan to make any new cards that specifically target IIsi.

Unfortunately there are no complete 68030 softcores, so FPGA is out. By the time you've gone through all the effort to interface the FPGA though you'd not necessarily beholden to a strict multiplier. Not something I have any interest in playing with anyways.
