Hi all,
This is a very interesting discussion. In the light of the wide range of
expertise here, has anyone interfaced a VP Oncore receiver with micro,
specifically an AVR? I'm in the process of doing that and am having some
difficulties. I'd appreciate some advice from anyone who has done it

When intel settled on the CS,DS,ES, SS architecture, they did so
because it made it easy to write pascal compilers.
That's no excuse.
Humor? Perhaps you are saying that you are omniscient?

One could equally say move 3000,x meaning x=3000. What's your point?

Dear Matthew,
Attached you'll find I document which I'm planning to upload to my
webpage (once it is activated). The TSIP settings you mention are
correct, however TSIP is used on Port 2! (Port 1 can be configured for
other protocols using TSIPCHAT).

Hi Didier,
.., I can use a pin that ordinarily
would run an LED as a diagnostic port.

too lazy to pull the 6805 emulator.
It's sort of funny, 20 years ago, I was flush with emulators, and used them

Sorry, but that is not so. The 68000 was a 16 bit machine, both
internally, and externally, with 32 bit registers and some 32 bit
instructions.

Peter,
You can set the Z3801A time format to UTC using the following command:
:PTIM:TCOD:FORM F2
To return it to GPS, use:
:PTIM:TCOD:FORM F2
And to query the current format, use:
:PTIM:TCOD:FORM?
These commands affect the format of the :PTIM:TCOD? Time query, and the
way the time is

Considering the access problems I have had with my ISP in the last couple of

It will take a day or so for the DNS system to flush itself.

FreeBSD will support a PPS signal natively. If you have a hard drive you
could just run a plain install, if you want to run off a CompactFlash module
then I would suggest building a NanoBSD image. It took me a few tries to get

Atime implementation on Linux (and I suspect maybe other *nix as well) was,
well, bad, maybe still is. Even if files are in the cache, the OS will
update atime on the disk.
There were talks of fixing that on Linux a while back, I am not sure if it
has been done. I lost track.
