[TUHS] mental architecture models, Anyone ever heard of teaching a case study of Initial Unix?

[Adam Thornton]

Indeed, S/390 Linux ran just fine on machines without IEEE floating point.
Which meant that for years I had to jam `use integer` at the top of any
Perl I ran, because otherwise any Perl arithmetic at all would go through
the software float routines, which was very painful on little machines,
such as a P/390.
