Okay, as long as it's a 68k chip, whether it's a 68882 or a 68881
doesn't matter much.

Hmm...

The accelerator board is disabled when you disable the extensions...
So, the CPU and FPU on the board cannot take over the machine from the
moment you turn it on...  I suspect your accelerator is not a simple
replacement for LCIII's on-board CPU, and that's why NetBSD chokes on
it...  It's just my guess, though...

Does anyone have the same accelerator?
