[RadioTelescope] Update

[Harry]

Hello

Just added the JTAG connector to the stepper controller interface shield.

The electronics is here in my office but I can bring it to UCC and install in
the electronic box as needed.

The box presently needs to be open with a fan blowing into it to keep the high
power stepper driver boards cool. Some consideration of an off the shelf rack
for the boards with fans (or space for fans) would be useful. Also whether the
DC supply needs to be replaced with something off-the-shelf. This still needs
to be determined.

All the best
Harry
