Portal R2E CCMC was a portable microcomputer designed and marketed by the Réalisation et Études électroniques department of the French firm R2E Micral,[1] and officially appeared in September 1980 at the Sicob show in Paris.[2][3] Osborne 1, the first commercially successful portable computer, was only released eight months later, on 3 April 1981.[4][5]

The machine was designed with a focus on payroll and accounting. Several hundred Portal computers were sold between 1980 and 1983.

Extremely rare, no museum has a Portal, and only two are in private collections.[6][7]

The company R2E Micral is also known to have designed "the earliest commercial, non-kit computer based on a microprocessor", the Micral N.[8] One of these machines was sold for 62,000 euros to Paul G. Allen, the co-founder of Microsoft (with Bill Gates), by the auctioneer Rouillac on June 11, 2017, for Allen's Seattle museum, Living Computers: Museum + Labs.[9][10][7]

Specifications edit

The Portal was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz.[1][11]

It was equipped with 64 kB of main RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (in separate blocks), a LED 32-character one-line screen, a floppy disk (capacity - 140000 characters), a thermal printer (speed - 28 characters/second), an asynchronous channel, a synchronous channel, and a 220-volt power supply.[1][11]

It came with two operating systems: Prologue and Basic Assembly Language (BAL).[1]

Designed for an operating temperature of 15 °C to 35 °C, it weighed 12 kg and its dimensions were 45 × 45 × 15 cm.[1][11]
