Talk:U80601

Reverse Engineered?
How was it developed? Did they reverse engineer it, or just copy the die using a microscope, or reimplement their own new chip with the same instruction set? — Preceding unsigned comment added by 82.139.82.82 (talk) 16:52, 4 August 2015 (UTC) According to the German Wikipedia page on the MME U80601 it was "reverse engineered" by VEB Microelectronics Karl Marx Erfurt combine, where design began in 1986 and culminated in production in 1989. I found some English translations of East German journal articles describing the U80601 after its launch. The East German engineers (naturally) did not admit to reverse engineering Intel's 80286, but instead claimed it had been designed for downward compatibility with the Soviet 16-bit K1810 WM86 microprocessor. It certainly looks very suspicious, but I couldn't find a credible source to cite. Loresayer (talk) 05:43, 28 August 2015 (UTC)
