{{anchor|EL-5500|EL-5500II}}The '''Sharp PC-1401''' is a small [[pocket computer]] manufactured by [[Sharp Corporation|Sharp]]. It was introduced in 1983 and is one of the first combinations of [[scientific calculator]] and portable computer with [[BASIC programming language|BASIC]] interpreter/bytecode compiler. The '''PC-1402''' has the same features but includes 10K of RAM.

==Technical specifications==
*[[Central processing unit|CPU]]: [[Hitachi, Ltd.|Hitachi]] [[Hitachi SC61860|SC61860]] (8-bit CMOS), 576 kHz clock frequency
*4 [[Kibibytes|KiB]] [[Random Access Memory|RAM]] (3534 bytes usable) (Two 2К×8 CMOS Static RAM HM6116 chips)
*40 KiB ROM (SC613256 chip)
*Display: monochrome [[Liquid crystal display|LCD]] 16 digits (5×7 [[pixel]]) in 1 line  (Controlled by SC43536 chip)
*Integrated piezoelectric [[Loudspeaker|speaker]]
*Keyboard: 76 keys, 1 switch on front, 1 key, 1 knob on back/side
*11-pin serial connector for [[Computer printer|printer]]/cassette controller {{ill|Sharp CE-126P{{!}}CE-126P|de|Sharp CE-126P}}
*Powered from two CR2032 [[Battery (electricity)|batteries]],  power consumption is less than 0.03 W
*Size: 170×72×9.5mm, weighing around 150 grams

== 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 ==

=== {{anchor|EL-5510}}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.

=== {{anchor|EL-5400}}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.

=== {{anchor|EL-5520}}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 F

40 FOR I=1 TO N STEP 1                 ''counts I from 1 to N
50 LET F=F*I                           ''calculates F=F*I
60 NEXT I                              ''repeats loop from line 40
70 PRINT USING "##";N;"!="; USING ;F   ''print result - i.E. 5!=120
80 END                                 ''end of program
