HM6116 (was: semi-OT)

there's a 1982 "Semiconductor Data Book Hitachi IC Memories" on my desk,
and a scanner in the next room. The book has seven pages about the
HM6116LP-2, HM6116LP-3, and HM6116LP-4, including a general decription,
pinout, data tables, signal waveforms, and various diagrams.

I might send some GIFs by mail to you privately, or if somebody has a
place to make them available on the Web, please let me know. I don't
think Hitachi would mind. I didn't even find a copyright notice in the

Minimum Cycle Time for the "-3" version is 150ns, access times from
either chip select or address input are also 150ns.

Minimum VCC for data retention: 2.0V.

Anything else you need in advance?

Nothing about the Intel chip, however.
