Adding physical RAM to the 41C

[DanLins]

Years ago, there was an article in PPC about adding a HP #82170-60001 ram chip inside a 41C case, which turned it into a 41CV without taking up a port. I asked Richard Nelson recently if he knew where I could find find the article, but he did not recall seeing it. He did tell me that he has sold all of his calculators and related materials and now concentrates on his 48 and RPL.

Does anyone here recall seeing the article, probably back in the early 1980's?

Thanks,

Dan
