It's nice to see some other "non mainstream" Amigas out there. My list:

A1000 with 1MB board and 68010
A1000 with 1.5MB board
A2000HD with '030 and Toaster (100MB disk)
A2500 with '030, genlock and '286 coprocessor (100MB disk)
A4000 with '040 and Toaster (2 x 850MB disks)
A4000T with '040, Toaster and timebase corrector / sync generator (2GB disk)

There's also a '286 PC which I believe is just there for its ISA backplane 
and is hosting a bunch of video-related cards - that along with the 
A2000HD, A4000 and A4000T all came out of a TV production studio. There are 
also a few hand-held sync/channel controllers, too, but I don't know what 
else I'm missing in order to make everything "do stuff".

The A4000 is, at least for now, beyond hope - it had quite extensive 
battery corrosion and wasn't showing signs of life even after going over it 
with a loupe and patching PCB traces. Either I missed something, or there's 
internal damage to one or more of the ICs. I did swap the A3640 into the 
A4000T, so I know that's working and the fault is local to the main logic 

Oh, as you have one too, any idea how many A4000Ts were made? I've been 
curious about that lately. It seems that Commodore put out around 200, but 
I can't find figures/estimates for the Escom-built machines (which mine is).
