I don't believe that Tek service guys had to unsolder anything to re-program the newAll the original non-windows TDS's except the 200, 300 and 3000 series
had their F/W updated through the GPIB connector. To update the 300's
a special pod was connected to a connector on the main board. The other
end of the pod was connected to a PC with both GPIB and RS232. It was
powered by an 18 VAC adapter. The pod P/N was 067-1436-00.
The THS's used the same pod plus a cable adapter to connect to a connector
under the keyboard. To update a special DOS software in conjunction with
the F/W data files was used.
According to the info I have the THS non-A and A are not compatible.
