I have completed and tested the design of my ATX controller. It has been
tested with 12 different 20 and 24 pin ATX 2.X power supplies ranging
from
180W to 750W.
It works perfectly.
I am now taking this prototype and turning it into PCB form. It will
allow
anyone who has cased their QL to case it in an ATX case with proper
power
supply control. This will dramatically widen the choices for cases,
and when
combined with a backplane will allow ultimate expansion choices. I have
designed it so a flying lead can also supply well-regulated +5v
through the
QL expansion interface, and/or through the location where the 7805
voltage
regulator normally fits.
I will be traveling the next few days, but I will publish the gerbers
and
schematic when I get back, and do the math on a small production run
next
week.
Have a great weekend, everyone!
Sounds great. "Traveling" and "Math" though - you are becoming an
American (8-)#

Do you remember me suggesting that you made something like this back in
the old days - on on eof our many QL jaunts? When we were talking about
new products.
