OK, just be warned that the do-it-exactly-right '020 and '030 interfaces
are non-trivial.  Little details just keep popping up and kicking you
back in the direction of square 1. 

I haven't seen a Lucas boards, though the noises are generally positive.
You might comtemplate implementing one on a PCB to fit the A2000 slot.
Note that I'm not stating whether the Lucas board is 100% right or not,
but at least it's an active project and you stand a chance of finding out
how to fix/upgrade it...
