rats, that sorted that problem. The setup directions on the website
(which imply they cater for both Windows and Linux) are wrong - they
reference a 'basic2.rom' file and 'dfs-1_44.rom'.

Oh, I also had to find the Speech! rom before I could get any further.

seems that's still the case :-(

I get:

  Version: 0.9DAG 10/12/2000
  an X error on display :0.0text: BadMatch (invalid parameter
attributes)

.... then it drops back to the shell prompt. Presumably related to the
colour depth.

I'm just surprised nobody's wanted to run this in the last 4 years under
Linux!

Heh - maybe someone on this list will see this and update the code a
little! Unfortunately I haven't done any X programming for years :-(

Time to find room on the desk for a real BBC I think! :-)
