Speedier bridgecard?

In the conference with Dave Haynie of Commodore, a question was asked if the 8088 on the bridgecard could be replaced with a NEC V20. Dave did not know for sure, but he thought it could be. Is there any other way to speed up the bridgecard, i.e. replace a clock timing crystal with a faster one like was done on 6 MHz AT's? Dave said that the bridgecard interface chips had some leeway in them to allow for future boards, like the 286 bridge-10MHz, so this approach may be possible. How about the 286 accelerator boards? From what I know about 286 accelerator boards, this may not be possible. Many of the boards require you to remove the 8088. I don't know if the bridgeboard will still communicate with the Amiga with it's brain removed. Any thoughts?

It should work if the custom chips are not too timing sensitive. Since I did not read the transcript of the conf, I don't know if that was said. Howevere, judgin judging from what you wrote, I'd have to say that might not be a problem. It's the same problem faced in clones, if the slower chip is pulled, does the floppy controller base _everything_ on timing signals from the CPU? God (/CBM???) only knows!. –Gabe
