Hey, Grandpa ;-)

"Like the time we went over to Shelbyville during the war, I wore an
onion on my belt....which was the style at the time...you couldn't get
those white ones, you could only get those big yellow ones..............
...now where was I........oh yeah,..."

I've seen some of those schematics, and often there's an "All values
in uF unless otherwise stated" legend. Which is OK because at least
you know where you are. Still don't like DPs though

What about the 3-digit format ? eg 104 for 100n, 222 for 2n2 etc
(101 for 100pF, 100 for 10pF !!!) That never made it into schematics
AFAIK (possibly because you have the luxury of space in a schematic
that you don't have on a component) although it's a perfectly clear and
succinct label - SMT resistors for example
