Subject: Spotting an upgraded model A

Hey up,

I've been given a BBC B and a Master - both boxed, with manuals. The original
owner is of the impression that the Beeb is actually a model A that has been
upgraded to a B. So I thought I'd check here and ask if anyone knows the
telltale signs. Briefly:

1. The manual that comes with it is a "provisional copy", not the standard
spiral-bound user guide.
2. The motherboard is marked as "Issue 3".
3. Half the RAM ICs are socketed - not soldered directly on.
4. There are one or two board modifications done (a short wire or two going
from a point on the board directly to a leg on an IC, for example).
5. The plastic keystrip just says "BBC Microcomputer" rather than specifying
a RAM size.

For those who are interested ... both machines will probably be going on eBay
soon, with profits going to charity (as usual).

All the best,

Kris.
