As a first post I thought I'd share a success story.
After a lot of flailing about the magic combination to upgrade a TS-2100
from old/ROM firmware appears to be to ensure the line endings on the
file match that of the TFTP host. While it is twitchy about ethernet as
long as there's no contention

OK so the pinout vaguely matches, the TS-2100 is *very* twitchy on the
alarm circuits, even a 1Mohm scope (well, it's 1M in theory, cheap

Yeah, there was a LPRO Rb option on that board and you are
remembering correctly. The main thing was a dc-dc converter to get the

I'm wondering if anyone knows exactly which power connector the

fairly useless), and a trawl of mouser seems to indicate it's a MiniFit

Trimble has/had at least 2 units like that: Palisade and Acutime. There have
been several variations of the Acutime.
So I can't just plug a Palisade into an Acutime rack?

We had idiots with fireworks here too, as apparently did much of Melbourne.

Does anyone know if there's anyone who sells essentially just the oven &

I have a project for which I'm currently using a VCTCXO, but I'm
wondering if enclosing a plain VCXO, plus the control DAC & voltage
reference in a single small oven would end up more stable,
I'm somewhat tempted to take the schematic and see if I can fit it in
the comparatively tiny Pomona boxes, although I have far too many side
projects already, enough 10MHz taps, and I still need to do the terminators.
The VersaTaps are supposed to be an actual synthesizer IIRC.

I'm looking at using a Spectracom 8140 for 10Mhz distribution, and they
specify using a DC-blocking 50-ohm terminator on each run.
These seem to be odd enough that none of my usual sources have them
(75-ohm DC-blocking terminators yes, 50-ohm, no).
While it's easy enough to chain a DC block and
