Re: DEC DE201 network cards (is anyone familar with them?)

The subject seems to have moved to 10Base-T / RJ-45 pinouts
the following colours are AT&T standard
its the pairs & polarity that are critical though
pin  normal    crossover
1    wh/or     wh/grn
2    or        grn
3    wh/grn    wh/or
4    blu       blu
5    wh/blu    wh/blu
6    grn       or
7    wh/br     wh/br
8    br        br

a normal cable (pc-hub, wall-pc, wall-hub, wall-wall)
is normal both ends 
a crossover cable (pc-pc, hub-hub)
is normal one end crossover the other 

note: some cables the white is not marked with the colour
so you need to strip them carefully to preserve the pairs
which will be lightly twisted together. Also try and keep
pairs twisted as close to the connector as possible.

Regards
Adrian
