Heh, heh, I know the problem well.... ;-)

Personally I'd say more.

A few years ago I decided to get a formal qualification in electronics (I've
been a hobbyist since '77). As part of the course we had to learn the proper
techniques for fault finding digital systems....we were taught these using
microProfessors and similar 6502 based boards (I forget their name....hex
keypad, couple of VIAs, LED readout etc).

"Primitive" systems like these (and Apples and Beebs) I think are far better
animals on which to learn the inner workings of computers, far too much is
hidden away inside the VLSIs our PCs are made from these days. :-(
