Calculators with C?

[xerxes]

There are some pockets from CASIO (VX-3, VX-4, FX-870P, FX-890P, Z-1, Z-1GR and Z-1GRA) and some from
SHARP (PC-G813, PC-G815, PC-G830, PC-G850, PC-G850S, PC-G850V and PC-G850VS) offering a C interpreter
besides BASIC. The first pocket offering different languages was the CASIO AI-1000 from 1988. It comes
with built-in LISP interpreter and the possibility to add other languages via ROM cards (BASIC, PROLOG,
CASL, C, PASCAL). In 1989 CASIO made the export version of the AI-1000 with built-in C instead of LISP,
called PB-2000C. LISP is available on the AI-1000 only, because there is no LISP ROM card. There is also
a CASIO PB-1000C, but the C refers to the built-in CASL and not to the C language.
