Anybody remembers the Signetics' Write Only Memory (WOM)?

Yep. It was originally product released in EDN or Electronic Design
magazine. Signetics then had a contest asking for suggested
applications. I submitted a fair sized list and was rewarded with a
plastic disguise mask and a printed data sheet. It had eye glasses, a
fake nose, and fake eyebrows. Most of the applications listed on the
data sheet sound like mine. I believe it was used in early Unix
machines as a /dev/null depository.
