Warning - DIY content
I finished testing the proto-type of the 822 circuit tonight and it works
great. Of course, I found a couple of mistakes in one of the pieces of
documentation. Two of the jumpers were omitted from the proto-board layout
paper drawing. I somehow missed these when I was doing the layout. The
spot for them was reserved, but I forgot to draw them in. The documentation
has been fixed. So, if you have retrieved any of the 822 data, it is all
fine but you need to replace the protoboard layout drawing. The schematic
is fine.
