To Fast:

(i now understand the oxygen part,thought i found a slip in your trip(to coin a phrase) to our(or 1975…) time… why is it you traveled to 1975 anyway??)

The first “leg” of my trip was from 2036 to 1975. After two VGL checks, the divergance was estimated at about 2.5% (from my 2036). I was “sent” to get an IBM computer system called the 5100. It was one the first portable computers made and it has the ability to read the older IBM programming langages in addition to APL and Basic. We need they system to “debug” various lagacy computer programs in 2036. UNIX has a problem in 2038.
