RE: Casio's and Complex Numbers
Quote:Just found a link for an Argos catalogue from 1982 with the FX82 in it, so that must have been what I had then. Oh, OK! It is likely then that the FX80/81/82 followed the years in terms on introduction 1980,1981,1982 (I did think this once though!), thinking about it a near 10 year gap between the FX81 and FX82 didn't make sense! Quote:I'm not sure why some LCDs had yellow filters, but I don't think they had any protective function. I just read that somewhere so may well be wrong, but for sure after around 1980 no manufacturer were using them... My first "real" Calculator was at University as well... an HP12C from a thrift shop in Victoria (Canada) back in 1995, before that believe it or not I was using a Z88 for a lot of stuff.... but a bit big for School!!! HP-28S (1988 US model), DM41X (2020) |
