Elliott 503 and 803 were 40-bit machines, 39 data bits + one parity
bit and from the early 1960s.
We have the backing-core stack for the 503 and Bill's stack is quite
different. We also have the main core stack for the 503 but not seen
directly as the example we have is still in its cooling shroud.
I can't find pictures of the 803 core stack but here are pictures of
the 503 core stacks:
