You could try a delete break (or any other key than N and D plus break) so
that the cassette filing system is entered instead. 
I must apologise for the slack wording on the website there, the ANFS or NFS
chips are very unlikely to actually say "ANFS" or "NFS" on top of them, more
likely they'll just me a paged ROM in IC35,44,57,62,68 and not IC71).

Note that IC37 and IC29 are for the speech upgrade, which I can supply too!
