Hi
The only other wrinkle worth noting is that you may have to delay the carries
out of the count blocks. All of the same stuff still applies, you just wind up
with two delays where you thought you would only need one.

That looks like a problem inside the TBolt. I'd guess that the CPU or RAM or
ROM is flakey.
I'd put a meter and scope on the power supplies to double check. If that's
OK,

"There are a couple of European sources that pop up from time to time selling
Thunderbolts. It appears that 99% of the supply comes from China. At least
here in the US, it's significantly cheaper to ship them in from China than
to buy from a "local" source."

Hi John,
It is always possible. They were cheap monitors, so the obvious
solution was to trash them, and avoid putting monitors anywhere near
the shaker unit.
I do recall that the shaker made monitors swim from many many yards
away. Some better shielding would have been nice.

Hi
I *think* you are asking if there's a clock that automatically corrects for
relativity. Simple answer is no. You certainly could do the math in a PC and
then drive a suitable clock with the required offset data based on a known
location for the clock.
Gray code is one of those th

Can you put a little solder on the threads of your bolts? Probably good

Hi Ernie,
You can get M5.5 screws fairly easily (in the UK at least) It's actually a
"cheat" size, almost identical to the old 2BA screw. 2BA was used in electrical
fittings and there were so many in use that a replacement was required that
fitted older fixed installations like junction boxes ce
