CP/M V3.0 for the Z-80 allowed redirection. It wasn't quite transparent, but
it did it.

Hi Patrick,

Thanks for the detail. Great.

I think that Kildall was dead before DRI was bought by Novell. I don't think
he
could ever have been a second Bill Gates though - he just wasn't like that.
He
had a life - though short. I don't think Gates has ever had a life.

I take issue here. There is no connection between CP/M and Unix. MS-DOS post
v2.0 has a sort of Unixy file system and sort of does redirection and piping
which were obviously inspired by Unix (Xenix?), but its very superficial.
I'm
sure there never was any common code between MS-DOS and Xenix. For one
thing,
one is written in assembler, the other in 'C'. So your circle is more of a
line:

CP/M -> DOS -> Windows

I see Unix as a totaly separate line.

Chris.
