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.

It was equipped with 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 -), a thermal printer (speed -), 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 to, it weighed and its dimensions were 454515cm.[1] [11]
