Sharp PC-1401 explained

The Sharp PC-1401 is a small pocket computer manufactured by Sharp. It was introduced in 1983 and is one of the first combinations of scientific calculator and portable computer with BASIC interpreter/bytecode compiler. The PC-1402 has the same features but includes 10K of RAM.

Technical specifications

Hitachi SC61860 (8-bit CMOS), 576 kHz clock frequency

Peripherals

The machine has an 11-pin serial connector, which is almost through-hole compatible. This connects to a proprietary thermal printer, such as a CE-126P. The printer will also serve as an adapter to connect to a tape recorder. The tape recorder provides program and data backup.

Variants

PC-1421

The PC-1421 is a variant of the PC-1401 for financial calculations. It differs from the PC-1401 in the contents of its ROM and higher CPU speed. The PC-1421 CPU clocks at 768kHz vs 576kHz for the PC-1401.

PC-1430

The PC-1430 is a stripped-down variant of the PC-1401. 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.

PC-1450

The PC-1450 supports user changeable RAM cards: CE-211M (3070 bytes = 4 KB / Standard), CE-201M (7166 bytes = 8 KB) or CE-202M (15,358 bytes = 16 KB).

Program examples

10 "F" allows to start the program with DEF F20 INPUT "N=?";N Ask for n30 LET F=1 Set start value of F to 140 FOR I=1 TO N STEP 1 counts I from 1 to N50 LET F=F*I calculates F=F*I60 NEXT I repeats loop from line 4070 PRINT USING "##";N;"!="; USING ;F print result - i.E. 5!=12080 END end of program
