Portal R2E CCMC was a portable microcomputer designed and marketed by the studies and developments department of the French firm R2E Micral and officially appeared in September 1980 at the Sicob[1] show in Paris.[2] The Osborne 1 was released eight months later, in April 1981.[3] specializing in payroll and accounting.
Several hundred examples were sold between 1980 and 1983.
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, one of the last examples of which 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 Computer Museum + Labs.[6][7][8]
Specifications[9][]
The Portal was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz.
It was equipped with 64K bytes of main RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (in separate blocks), a 32-character screen, a floppy disk (capacity - 140 000 characters), a thermal printer (speed - 28 characters/second), an asynchronous channel, a synchronous channel, and a 220-volt 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.
