My pocket money is clearly going to be burning a hole in my pocket with all your fantastic ideas.

Any chance of a TF3/4000 card to support BUFFEE?

Appreciate the big boxes have a number of big accelerators but there hasn’t been much since the a3660 so it would be great to see a option for these.

Buffee to TF bus runs at 100Mhz. TF doubles bus cycles up to 32bit. So no slowdown from buffee being 16bit (well there is a 10ns penalty over a TF1260)....
Nice!!

Seen a few weird and deranged posts about Buffee on A1200 only having 8Mb of ram....

TF1200 + Buffee will have 5.5Mb ZII ram (for PCMCIA compatibility), second IDE and 512Mb of ZIII. It will run A1200 bus 32bits wide and TF will talk to Buffee at 100Mhz.

But you wanted you can also run a 50Mhz 68000 in a carrier and not worry about the 6800 bus since the TF doesnt use it. But thats sort of a crazy use case.
