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.
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.
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.
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.
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).

The IBM Personal Computer is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by William C. Lowe and Philip Don Estridge in Boca Raton, Florida.
The Commodore PET is a line of personal computers produced starting in 1977 by Commodore International. A single all-in-one case combines a MOS Technology 6502 microprocessor, Commodore BASIC in read-only memory, keyboard, monochrome monitor, and, in early models, a cassette deck.
The KIM-1, short for Keyboard Input Monitor, is a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price and easy-access expandability.
The Intel 4004 is a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. Sold for US$60, it was the first commercially produced microprocessor, and the first in a long line of Intel CPUs.
The TI-99/4 and TI-99/4A are home computers released by Texas Instruments in 1979 and 1981, respectively. The TI-99 series competed against home computers such as the Apple II, TRS-80, Atari 400/800, and VIC-20.
The FM Towns Marty is a fifth-generation home video game console released in 1993 by Fujitsu, exclusively for the Japanese market. It is often claimed to be the first 32-bit CD-based home video game system, although it has a 16-bit data bus, just like the earlier Commodore CDTV and Sega CD, which both have Motorola 68000 processors that are similar internally 16/32-bit, but with a 16-bit data bus. The console came complete with a built-in CD-ROM drive and disk drive. It was based on the earlier FM Towns computer system Fujitsu had released in 1989. The Marty was backward-compatible with older FM Towns games.
The Sharp PC-1251 was a small pocket computer that was also marketed as the Tandy Pocket Computer.
The Sharp PC-1350 is a small pocket computer manufactured by Sharp. The PC-1350 was introduced in 1984 and was used by engineers, and favored by programmers for its programming and graphical capabilities. It was superseded in 1987 by the PC-1360, which featured one additional RAM expansion port, improved BASIC, floppy disk capability, and a faster CPU.
The Sharp PC-1403 was a small scientific calculator and pocket computer manufactured by Sharp. It was the successor of the Sharp PC-1401, and had better display, more RAM and better system software.
The Sharp PC-1500 was a pocket computer produced by Sharp between 1981 and 1985. A rebadged version was also sold as the TRS-80 Pocket Computer PC-2.
The Sharp PC-1211 is a pocket computer marketed by Sharp Corporation in the 1980s. The computer was powered by two 4-bit CPUs laid out in power-saving CMOS circuitry. One acted as the main CPU, the other dealt with the input/output and display interface. Users could write computer programs in BASIC.
The TRS-80 Model 100 is a portable computer introduced in April 1983. It is one of the first notebook-style computers, featuring a keyboard and liquid-crystal display, in a battery-powered package roughly the size and shape of a notepad or large book. The 224-page, spiral-bound User Manual is nearly the same size as the computer itself.
The Sharp PC-E500S was a 1995 pocket computer by Sharp Corporation and was the successor to the 1989 PC-E500 model, featuring a 2.304 MHz CMOS CPU.
The Dick Smith Super-80 was a Zilog Z80 based kit computer developed as a joint venture between Electronics Australia magazine and Dick Smith Electronics.
The Sharp PC-1600 was a pocket computer introduced by Sharp in 1986 as a successor to the PC-1500. The PC-1600 provided compatibility with its predecessor through the use of a slave CPU that could run assembly language programs targeting the older machine. It could also switch into a compatibility mode so that programs written for the single line display of the PC-1500 could work with the four line display of the PC-1600.
The Intersil 6100 is a single-chip microprocessor implementation of the 12-bit PDP-8 instruction set, along with a range of peripheral support and memory ICs developed by Intersil in the mid-1970s. It was sometimes referred to as the CMOS-PDP8. Since it was also produced by Harris Corporation, it was also known as the Harris HM-6100. The Intersil 6100 was introduced in the second quarter of 1975, and the Harris version in 1976.
The Sharp PC-E220 was a 1991 pocket computer from Sharp Corporation featuring 32 KB RAM, 128 KB ROM and a 3.072 MHz CMOS-SC7852 CPU which was Z80A compatible. The display was able to display 4 lines x 24 characters/144 x 32 pixels. Programming languages were BASIC and Z80-Assembler.
The Matsushita JR series was a line of microcomputers produced by Matsushita Electric Industrial during the 1980s. Based on the success of the Sharp MZ and NEC PC-8000 series, it was an attempt by Matsushita to enter the personal computer market.
The Sharp pocket computer character sets are a number of 8-bit character sets used by various Sharp pocket computers and calculators in the 1980s and mid 1990s.
The Gigatron TTL is a retro-style 8-bit computer, where the CPU is implemented by a set of TTL chips instead of a single microprocessor, imitating the hardware present in early arcades. Its target is the computing enthusiasts, for studying or hobby purposes.
