Hi Mark,
After all the effort you just put in, you'll be a touch annoyed that Jamma
Boards have done a kit for TM500 extenders for ages ... OTOH you may know
about them and have decided you could do better.

LTE does support the long-standard NITZ (network information and time zone)
service. It's an easy way to find out just where you are without having to
change your TZ settings constantly. In fact, if you go to time settings on HTC
Android phones, the 'automatic time update(NITZ)' setting turns
I believe I would be interested in two.

You can set it up to sync with you own ntp server. I think. You can just spot
check it.
Mark;
Could you describe your design a bit more? E.g.,
1) There are connectors at both ends of those cables; what are your socket
provisions for the module end?
2) Do you use 0.1 40-pin headers at both ends, or some other form of
termination?
BTW, I'd be interested in some, as well, depending on

I have seen the Jamma kit (I will be using their edge connectors) and John's
design. Their main problem is the hassle of wiring up 56 individual wires.
Also that tends to be not all that reliable... wires tend to break at the
solder joints.

Are standard disk cables a reasonable length? (and a pinout you can use)
I don't know the details, but there are two types of disk cables. The old
style uses standard 40 pin ribbon
Mark, that is a nice idea and much easier to construct. Count me in for two
sets.

Hi
I *think* it’s even more specific than that. I’ve watched it switch time
driving down the road in Indiana. As we did zig zags over the time zone line,
the iPhone quite happily changed displayed time. My guess was that it used GPS
location info to decide which side of the line it was on.
You can select the behavior you prefer...
SettingsGeneralDate Time. You can set it manually or have it set
automatically based on your current location.
Leaving to automatic uses a surprising amount of battery power.

I've heard that people who live near time zone boundaries (very near, like
within a mile or two) often have to switch automatic setting off, because
the time might be an hour off depending on which tower their phone connects

Emerald Time is a very nifty little app, and yes, I've used it a number of
times to check my phone's displayed time. It's often off by more than two
seconds but never more than three, so far.
There are several other apps that can check the time with NTP, and display
it in different formats,
Am I right in thinking that two of these connector/cables would give the
full facilities on the 5000 series units.

you would have to dig around and look. I am sure there is. I have played
with it for a year or two. I put my own ntp server in there and was
frequently disappinted that it would prefer remote servers quite often..
which cant be better than mine. I dont get that but otherwise I like it.

Yes, all 56 pins are extended, including the PWR pin unique to the 5000
series (it is a power good/power-on reset sort of signal).Several of the
TM500 modules are also double-wides and need two extender cables.
I have not done an extender for the GPIB connector, but that would be easy to

Yes, Apple does not present an (unpriviledged) iOS API to set the

a good thing.

You are right thats why I am thinking about 2.
On the ribbon cable discussion I do agree ribbon cable can be fragile
unless solidly tied down then they are pretty stable.
An approach I have used in building extenders for RS sig gens that use
Euro boards is the same stranded wire type for all pins.
Yes indeed this is very interesting.
I have a number of TM500 modules that need TLC every now and then.
I may also want two.

Well, just for grins, I did a small board for extending the TM5000 GPIB
connector. I remember that the last time I extended the GPIB bus by hooking a
ribbon cable to the TM5000 mainframe motherboard it was a bit of a hassle to
get to. These should make life easier...
