ILLIAC was a hypercube, I thought.  Not sure about Transputer.
Chessboard would be 8 interconnections per PE, I'd hope (kingwise
moves).  It seems unfortunate that the GA didn't also have 8, since it
would still be very local, yet make routing a lot easier.  Some
further-reaching interconnects would be good too.  FPGA's have a mix of
these, from what I understand.

The GA144 has XOR, their assembler just use the mnemonic OR for it, due
to idiosyncracy.

They're committed to stack machines, which have had some success, but
yeah, more memory would help it a lot.  Not necessarily ram: with some
program flash at each node, the 64 words of ram would then be sufficient
for lots of things.

Somebody is buying all those raspberry pi's...

Maybe in the 1980's.  That wouldn't compete today with the ubiquitous
ARM cores and compilers everywhere.
