Started learning MPUs in 1980. Took training from Motorola, Intel, NSC, Zilog, AT&T (Unix), Wind River, LSI Logic Gate Array Design and others. Have experience implementing many RTOS's, Solaris, AIX, HPUX and linux. About to start playing with SoC's and the newer MCU's as a hobby and so I can teach my son about them. Play time includes Amateur Radio, local Cub Scouts treasurer and helper at Cub Scout functions. I do computer systems and network consulting and run a high performance (linux and linux cluster) computer systems business.
