I've recently acquired a B+ as a replacement for a long lost standard
Beeb but there's a lot of my old software which refuses to run.  Most
things (eg Sabre Wulf, Overdrive) seem to freeze the machine after the
first stage of a multi-part load, with or without the Z-Break
combinations.

Does anyone have a summary of B/B+ differences, and any other tricks
for improving compatability?

Thanks
