I have been working with electronics for more than 40 years.   I done assemble programing from main frames to micros. Software systems to control system. I have worked with DOS, SysV Unix, concurrent DOS, CPM  and Digital Equipment OS, Windows and Linux.    

In the 70's I purchased a small security company which I managed for many years that grew to one of the largest security companies in the state. My love for programing continued as I wrote most of the software for the company.  

When I sold the company I decided it was time to get certified on todays current systems.    Cisco for networking (which is a lot of fun), Linux because it is a great OS, A+ for hardware and Microsoft because some people expect it. Also many other small certs but who care anyway.

I still enjoy microprocessor based electronics, Java and C programing. My  OS of choice is Linux. 

In the middle of difficulty lies opportunity.
