This one has two bigger chips and some logic glue.  The ROM is stamped
"9316B-4E92/CURRAH 104/GI 8315 CEA", and the speech chip is indeed a
SP0256-AL2, also stamped AEC 1 and GI 8315 CKA.

Funny that they call it SPO256 much of the time.

Thanks for the links!

Larry Anderson's suggestions didn't work.  INIT and SAY are not recognised
as commands.  I didn't find any keywords with a quick look at the ROM either.

Someone got another Vic-20 speech cartridge recently and asked for information
on the comp.sys.cbm newsgroup.  I'll probably have a look at that cartridge
in a couple of weeks.  I don't know if the case of that one can be opened,
though.  The one I got had been broken open violently.
