From: Joe <rigdonj(a)intellistar.net>
or
>400ft, 10mhz clock for a S100 z80 system that was
also distributed to
>other boards on the bus. A modification to the termination of that
line
virtually made
it disappear, the standard terminators didn't actually
match the impedence of the line making it antenna. Other hot one
was the Altair you could hear the 2mhz anywhere in the house
with the case on.
Was that being ratiated via the AC power lines or the keyboard cable what?
Joe
The altair just radiates.... All the jungle wire fromthe FP to bus.
There was no attempt to provide ground planes or decent grounding.
None of the systems I mentioned would have a "keyboard cable".
