LA4800 Pod

One circuit of a pod and some routing and we have a pod for the LA4800:

It's a bit big as I just wanted to see if the circuit was correct and I anticipated lots of scoping. As it turned out the only problem was the transistor pinouts and the orientation of the pod cable sockets. Neither of which is much of a problem. as the pod works.

Here's a quick trace of some signals on the Epson HX-20 IO port.

The analyser works perfectly as far as I can see, apart from the display problems, which really are a shame.
I had to solder wires on for this test as the clips I ordered haven't arrived yet, but that's fine.
