the Zilog Z80, came the Z80-based Micral CZ. The 8080-based Micral C, an intelligent CRT terminal designed for word processing and automatic typesetting, was introduced in July 1977. It has two Shugart SA400 minifloppy drives and a panel of system control and sense switches below the minifloppy drives. Business application language (BAL) and FORTRAN are supported. By October, R2E had set up an American subsidiary, R2E of America, in Minneapolis. The Micral V Portable (1978) could run FORTRAN and assembler under the Sysmic operating system, or BAL. The original Sysmic operating system was renamed Prologue in 1978. Prologue was able to perform real-time multitasking, and was a multi-user system. R2E offered CP/M for the Micral C in 1979. The R2E Micral CCMC Portal portable microcomputer made its official appearance in September 1980 at the SICOB show in Paris. It was designed and marketed by the studies and developments department of François Gernelle of the french firm R2E Micral at the request of the company CCMC specializing in payroll and accounting. The Portal was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz. It weighed and its dimensions were 45 cm x 45 cm x 15 cm, It provided total mobility. Its operating system was Prologue. Later Micrals used the Intel 8088. The last Micral designed by François Gernelle was the 9020. In 1981, R2E was bought by Groupe Bull. Starting with the Bull Micral 30, which could use both Prologue and MS-DOS, Groupe Bull transformed the Micral computers into a line of PC compatibles. François Gernelle left Bull in 1983. Legacy Truong's R2E sold about 90,000 units of the Micral that were mostly used in vertical applications such as highway toll booths and process control. Litigation followed after Truong started claiming that he alone invented the first personal computer. The courts did not judge in favor of Truong, who was declared "the businessman, but not the inventor", giving in 1998 the sole claim as inventor of the first personal computer to Gernelle and the R2E engineering team. In the mid-1970s, Philippe Kahn was a programmer for the Micral. Kahn later headed Borland which released Turbo Pascal and Sidekick in 1983. Paul G. Allen, the co-founder of Microsoft with Bill Gates, bought a Micral N by the auctioneer Rouillac at the Artigny Castle in France, on June 11, 2017 for his Seattle museum Living Computers: Museum + Labs.
