I'd not met this before. Apologies if it's general knowledge.

That's a cute little 6502 SBC, but when I think of a BBC Micro, I
remember coding children's games for it in 1984 with sound and
graphics. Was the Model B something else entirely or is this just a
text-centric subset?

In my somewhat vague recollection, many people /did/ use the BBC as a
text-centric machine, because in Mode 7, with the Mullard teletext
chip generating the display, you got the most available free memory

a network card to and used to use as a printer server.

True. Mode 7 only needed 1K of video RAM.

The oterh explanation is that if all the configuration swithces were
open, you got MODE 7 as the pwoer-on defualt. Sicne the DIP swithc (on
the keybaord PCB) was not fitted as standard, and few users soldered one
in, mackines nearly always powered up in Mode 7.

You rememebr correctly (or at least you could do ;-)). The original BBC
micro came in 2 models, A and B, they were built o nthe smae PCB. The A
had quite a few ICs not fited so it only had 16K RAM (as against 32K i
nthe model B) amd most of the interfaces were not implemented (in somce
cases this meant leaving out a couple of cheap ICs but fitting DIL
socketes in their palce so the machien could be upgraded later, I am not
sure this was sensible!).
All BBC micros had grpahics (rather better on the B model as some modes
needed 20K of video RAM which was clearly impossible on a 16K machine)
and soucd.

Actually, the original Beeb was a single-board computer (apart from the
PSU and keyboard which I doubt are on this board either).
