Jim-your memory is fine. most likely meant both "boring" types in similar package styles.....

Say, isn't the 2N3906 a PNP transistor?? And 2N3904 is the NPN complement?? Or does my memory from 30 some odd years ago fail me?
Thanks.

I thought about four drawers, each with maybe a dozen or sixteen bins (4 x 3 or 4 x 4).
The four drawers would be Small and Medium PNP (or P-channel) - Small and Medium NPN (or N-channel), Large PNP - Large NPN.
I use the same system, except instead of drawers I use plastic compartment boxes lined with aluminum foil. I also happen to have several hundreds of "boring" small NPNs (basically 2N3906s and similar), so that's a separate fifth group.
I keep track of individual transistors on my computer. For each group, I have a folder with datasheets for each part number, with available quantity and important specs (Vceo, Ic, fT, etc) in the filename. There is also a backup copy of the entire thing on a flash drive.
This system makes it very easy to tell what's in stock and identify substitutes. Once I decide on a specific part, all I need to do is to look through that compartment, and I already know what the part looks like because of the datasheet. It takes some care to set up and maintain, but the space savings and ease of use are incredible.
