Hallo Kees!

 KvE> I did some work on a microvax

That sounds interesting.  I am not sure what the mainframe was other than it
was manufactured by DEC and there were a number of dumb terminals wired into
it.  The one I used faced a bank of 9 track tape drives so that I had easy
access to them.  ftp and rlogin were the main networking apps I used on
VAX/VMS.  Same with on Solaris later on except I think by that time telnet
replaced rlogin.

 KvE> I dir read Fortran and once did a conversion to the very rich
 KvE> Basic that HP had on it's Desk calculators.

I never ran across Basic until later on when I bought my first PC, a 20MHz 386
with a 20M hard drive and a 2400 baud isa modem.  I used to connect to the
mainframe from home using that setup.  Also could connect to two different
Sparc stations as well over the phoneline from home.  It was around that time I
encountered my first BBS.

 KvE> one I remeber was gopher

I never used gopher but was aware of it back then.  ftp and telnet were my
mainstays even on X-Windows.  Despite the gui interface I was still using the
commandline and have been ever since up to and including today.  My terminal is
a framebuffer linux terminal and I haven't bothered with xorg although I have
used it off and on in the past.  So far six tty's are all I have ever needed
and probably only use four of them at any given moment, such as right now as we
speak.

 KvE> Only for the fact that I was young.

There are days I will agree with the above.

 KvE> It must have been Mosaic by Marc Andreessen

That sounds very familiar.  I think you nailed it except I never heard of Marc
Andreessen.  Mind you I never really used html all that much back then.  I
still don't other than text browsers like lynx and links, mostly links.  I used
to use lynx back in the 1990's and still keep it to do html -> text conversions
every now and then which is getting less and less these days.

Het leven is goed,
Maurice
