You put the 8085 on your workbench with the notch pointing up. Then
you connect all the left-hand pins together with #20 wire and 60/40
solder. Next you connect all the right-hand leads together in the same
manner.
Then you cut the zip-cord going to a table lamp so the hot wire is
exposed. You connect the line-side to the left pins, and you connect
the lamp-side to the right-hand pins. Either unplug the lamp first
or do not use a grounded soldering iron.
Now you have a microprocessor-controlled lamp. To turn it ON, plug
in in, to turn if OFF, unplug it. You can use this to illuminate
your Linux box.
FYI, a Z-80 works better. It doesn't get as hot. However, the
op-codes are not compatible.
