HP30b Calculator JTAG Connector
The HP30b is a repurposable calculator, but to do this you need either a serial cable or a JTAG connector. I have a JTAG adapter, so needed a hole in the calculator case for the connector.
A few minute on the milling machine and we have two neat holes in the back of the case:
The Eclipse setup for the JTAG was a bit of a pain but looks to be close to working now. I have to erase the flash and get my code on the board before it will work properly I think, as the security bit is probably set in the processor chip.
