I see fluke.i selling older GPSDOs consisting of a large board with the guts
(more or less) of a Thunderbolt, a smaller board with switches and
and a ribbon cable to connect them.
With a FW of 1.88 and date code a few years older than a Thunderbolt,
I would guess this was a forebear to the Thunderbolt.

>> Lady Heather depends upon the ability of the Thunderbolt to broadcast the time message automatically every second. Apparently the Palisade type units do not support this mode of operation. It might be possible to set up the software so that it requests the time message continuously and only accepts the time messages that indicate that the time has changed, but without a board to try and maybe some documentation who knows?
