In fact, after reading said article (or was it a nightmare while I slept?) I bought six (4+2 just-in-case) TOSHIBA TC5516AP 2048x8 BIT CMOS Static RAMs and now I cannot locate the article anymore...

Finally! After searching day and night since October 2016 for this article I finally found it again. Now I can sleep better.
The article appeared in the Jan/Feb 1984 Computer Journal of PPC on page 21. It does not show up in the table of contents because it is disguised as a letter from a reader.
It describes how to implant four 2K 5516 RAM chips into the HP 75 to spare the cost of a 8K RAM module. While the soldering in piggyback fashion would be easy, one would have to mill out part of the case to make the chips fit (or one could machine the DIL cases thinner, but that's more for the explorer type).
