Definitely. Like all design decisions they have their place. To really 
date myself I sent my Osborne 1 back to the factory for the 100 column and 
DS/DD floppy upgrade. The new video would work for a while and then die. I 
isolated the problem chip with a can of cooler. It was CMOS and when I 
replaced it with the equivalent 74LS problem solved.
