Started with PDP8 / 11 as a Student, then Electronics Engineering until company I worked for went into Business PC’s. Then moved to Sirius / IBM-PC then onto Apricot back into *NIX with AT&T Line1. Played with CPM/86, Concurrent DOS, Xenix, SCOUnix. Then Windows in all its modes, with *NIX in the background. With the demise of Win SBS we went hell for leather into Linux & Open Systems.
