Intel 8085 - interview?

[Eric Smith]

At some point I read an article or a transcript of an interview with an
Intel employee (or former employee) who had been involved with the design
of the 8085, describing how he had specified additional instructions over
those of the 8080, and they had been implemented in the silicon, but then
the decision was made to not document any of the new instructions other
than RIM and SIM.

I no longer recall which Intel employee that was, and can't find the
article or interview. Does anyone else remember that, and perhaps have a
copy?
