This follows Tony's reply.
I have little knowledge of DEC stuff and no knowledge of Beebs. I was sort of surprised
that a PDP-8e's boot sequence is very similar to a peecee's, but this is
fundamental to computers really, and this I had to learn. Apples and IBMs are somewhat
plentiful. The Commie 64 has a bit too much custom logic, even a Mac has less in reality.
Not a huge Apple II fan, but it seems to have little or none. A 5150 mainboard has zero
custom logic, not even a pal unless I'm mistaken (and there's validity in the
argument that a smidgeon of custom logic enhances learning - in that it would be a
comprehensive example). There are undoubtedly many examples that would nicely fit the bill
(and if you wanted to FORCE yourself to learn and delve into assembler and whatnot, get a
Tandy 2000! It don't run squat, besides a handful of items that were modified for it,
bizarro scientific and accounting packages. Zork. Hooray. Conspicuous by it's absence
on the list is Starflight!
Why - why WHY!!!).
I haven't looked at the pi much, besides reading an article some time ago somewhere.
At first glance I can't see how it can help a person learn hardware. No clue on that
one.

Hmm, I'd love to find an Apple II or an IBM 5150 (or '60, but I'm not too
bothered about having a hard disk). I don't think there are any even
remotely nearby though, which means shipping (and worse still, the
possibility of ebay prices)

The way that it helps with education and
learning is that instead of
telling someone to go buy and dedicate a laptop or other machine to a
lab purpose, and download say a DVD to load it one can tell them to
obtain a Pi and an SD card image to boot it on.
There are several examples of lab setups where this is already done both
by attaching adapters to outside things (relay boards, etc.) and another
which attaches to a breadboard.
The pi is not going to be the focus of the vast majority of these
things, but will be the computer vehicle that delivers the educational
setup.
It can be the center of a lesson say to learn to program things that
require only what it has to interact with, keyboard, mouse an display,
plus for the model b adding in a network.
Instead of picking up $25 random ecycled machine this is intended to
replace that role. Also if the need arises in the right setting it can
be the focus of the lesson.
One suggested in these threads, "what not to plug into the gpio pins".
Screwing up that lesson costs you another Pi. I suspect there will be
people who will jump in and plug thing in randomly, but they won't get
far. I suspect most people will figure out what to do with what is there.
