It might sound stupid, but I was wondering this right now. Why does most old readme files, especially .doc files, are written in all caps? I thought keyboards with lowercase letters capabilities existed for much longer than 1995? If you look through the TI-85 ASM games (Zshell) section at ticalc.org you might get an idea of what I am talking about.
(at least it's better than that 2004 era where a lot of people were wRiTiNg ThEiR fIlEs TiTlEs LiKe ThIs in the TI-BASIC section)
