Yes, I examined this in some detail last year
after mention on the list, and wrote it up:

That's a great write-up! Thanks!
Agreed!
I'm going to have to study the training manual for the EL-X1 in more detail, because
it describes how its ROM core memory works, and it doesn't seem to be an exact match
of either of the ones in Brent's document. Since it goes back to 1958 it seems to be
the oldest example, so it's worth digging out the details.
Thanks; if you find out some details or refs about the X1 ROM implementation, let me know,
I'll be interested to compare them and should add mention of it on my page at some
time as another application of the technology.
