Re: Green screen to GUI

You didn't go quite far enough back in the old
"way back" machine.

The legacy machine for all that we currently work on started
out waaaay back in 1971 on the System/3. This was the beginning
of what we all call the "midrange" systems.

With very little or no changes, many of the programs written for
the System/3 could be run on the current box.

Now, you might argue the 400 is really a grown up System/38, which came
out in '78.  That's fine, but Windows grew from MS-DOS which was a
re-badged version of QDOS (1980) which itself was an adaptation of CP/M,
which was released in '74.  Funny how even in it's infancy Microsoft
wasn't innovating but instead relied on acquisitions to gain their
technology.

Legacy platform: Windows / DOS / CP/M if you count the CP/M influence;
S/38 if you don't.
Major difference: The iSeries can still run that code from the S/38.


Of course, you can add that Unix was released in 1969, making it older
than both. :)
