It's probably reading the OS version using a *FX0 and expecting to see
OS1.20.
Tell him to try booting the Database disc with Ctrl-Z-Break or
Shift-Z-Break. I seem to remember an addendum
to the 1770 DFS manual regarding improved compatability with the 8271 disc
controller when those keys are held during boot; one of the effects of this
was also to make the machine report a 1.20 OS to any *FX0 calls to improve
software compatability. (As he has a B+, he should have 1770 DFS.)
I also seem to remember there was another method of determining the OS
release (apart from *FX0) but cannot remember what it was. Some very
naughty software looked for the text string "BBC Computer 16K32K" at $&c304
in OS 1.2.

A friend was running this (it is the original Database not the later
Viewstore) on a BBC B until it expired.
He has now tried to run this on a B+ (64k) but it is throwing up an error
message saying it 'not a BBC'.
Any ideas ?
