Monzo's ET history

In the entry for 270 on

/tuning/files/dict/eqtemp.htm

we have

270 1970s? Erv Wilson and John Chalmers
1997 Paul Hahn

I found this along with the other usual suspects (441, 494, etc.) less
than 1000 back in the sixties, and I believe John Chalmers was even
earlier. I don't think the 70s date is right.

In 1968 my brother ran a program for me on a mainframe at Berkeley, which allowed me to study in detail ets up to 1000 for primes up to 31. This meant I found a lot of things which had already been considered but which I had never heard of (46, 58, 72, 94, 99, 171, etc.) as well as things which perhaps only John had previously seen--111, 130, 140, 224, 270, 311, 342, 441, 494.
