My WP-34S : USB to Serial cable prototype

[ijabbott]

I tried Micheal Kathke's SIL socket technique, but ended up ripping off one of the pads on the PCB when I put the case back on. I obviously didn't make the whole big enough. I made the hole big enough and tried it on a second HP 30b. This time the hole was big enough, but as the sockets poked out slightly above the hole in the case, I ended up ripping four pads off the PCB when I slid the battery cover back on.

On my third HP 30b (when it arrives), I don't think I'll bother trying to fit SIL sockets!
