Sharp PC-1401

It was introduced in 1983 and is one of the first combinations of scientific calculator and portable computer with BASIC interpreter/bytecode compiler.

The machine has an 11-pin serial connector, which is almost through-hole compatible.

The printer will also serve as an adapter to connect to a tape recorder.

It differs from the PC-1401 in the contents of its ROM and higher CPU speed.

The display and case are mostly the same (except for fewer keys), but the PC-1430 lacks the calculator modus (for calculations the BASIC mode has to be used), it offers less functions, only 2 KB RAM, and no speaker or buzzer.
