[xerxes]

In fact the Z-1GR is a later educational pocket and similar to the PC-G850V. The PB-1000 however is a classic pocket computer
with BASIC and assembly language. The PB-2000C is an upgrade with built-in C and ROM cards for BASIC, Prolog, CASL and PASCAL.
The japanese version of the PB-2000C, the AI-1000 has a built-in LISP instead of C. The PASCAL card is a native code compiler
and very close to Turbo-Pascal 5.0. Forth is also available for the PB-1000.
