RE: HP41/71 Membrane overlay comparison
I was really surprised to find out the 71 membrane was 3rd party made. It is a good example of what could be done back in the day if someone cared to do a nice job at something.
Pictures taken with a Sony HDR UX5 HD camcorder in pic mode. Other than scaling them for 19 inch monitor size, I left them uncropped and unprocessed. That camcorder is another weird goomer in my personal electronics menagerie. 2speed HP41CX,int2XMEM+ZEN, HPIL+DEVEL, HPIL+X/IO, I/R, 82143, 82163, 82162 -25,35,45,55,65,67,70,80 |
