Extremely rare, no museum has a Portal, two are in private collections.[4][5]

The company R2E Micral is also known to have designed "the earliest commercial, non-kit computer based on a microprocessor" the Micral N, whose one of the last exemplary 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 his Seattle muséum Living computer Museum + labs.[6][7][8]



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

It was equipped with a central 64K byte Ram, a keyboard with 58 alpha numeric keys and 11 numeric keys (separate blocks), a 32-character screen, a floppy disk: capacity = 140 000 characters, of a thermal printer: speed = 28 characters / second, an asynchronous channel, a synchronous channel, a 220 V power supply. Designed for an operating temperature of 15 °C to 35 °C, it weighed 12 kg and its dimensions were 45 x 45 x 15 cm. It provided total mobility.
