Pretty sure they're not compatible I'm sorry! They're just using the same connector, which is industry standard (DIN). The electrical specification is different to the TT/Mega STE port. I'm not even sure if the MEgaSTE/TT follows the VME spec fully anyway, does it have 7 IRQ lines on the VME port?!

The Nemesis, CT1, Phantom etc were all quite similar. They all increased the speed of the entire system. There were many free designs about, eg the one by someone named green IIRC.

SDMA does DMA transfer for the hard disk and the floppy drive. I also think they share the same IRQ or something???

I think standard speed was 16MHz in the Falcy. You can do that mod as shown in the photo.

68881 is slower than the 68882, that the Falcon was designed for.

I've heard rumours that the 33MHz 68882 (68882FN33) can reach overclocked speeds of 64-80MHz for all you floaty point maths lovers!

Chances are your internal fuse in the MEGA STE has blown. Open it up, and look for a very small (5-7mm long) fuse, will be marked Fxxx (x being numbers). Check it with a continuity meter, chances are you'll need a new one. I think they're 0.5 amps.
