In this video we take a look at two early 1980s composite CRT displays. One is a ultra boring 9” security monitor. Not much to look at but compact and sturdily built. The other is a super sexy 12” amber monitor which looks like it was made from a groovy 1970’s portable TV chassis. Let’s see if we can get these two mini monitors working.
