We use the Trimble 9390 where I work.

Around the Y2K period we received new EPROM sets to put into the units.

I checked yesterday and they are displaying the correct day and year.

Let me see if I can find a spare set of EPROMS to download.

If you can, I would also appreciate a copy of the image files so I can

archive them for others who may be in need. E-mail attachment, in the
form of a ZIP or similar archive, would be fine.

Thanks much.

I think I can have use for those EPROM images as well.

It seems that some TimeVault units also is affected.

Cheers,

I have a 9390-5593 that does not display the correct date.
The GPS engine uses two processors and three ROMS.
These are glued together with an ASIC.
I contacted Trimble and they cannot identify their engine.
I have read the ROMs and am in the process of disassembling the code.
This is slow.

I suspect that my 9390 had a Y2K problem and/or a 1024 week rollover problem.

Is this possibly the same engine that you replaced the ROMs in??

Sorry to jump in, but does anyone have any thoughts on whether this
might also be involved in the odd year rollover issue seen on many
TrueTime devices?

This is the issue where the work around for the TrueTime clocks is to
use the F68 command to set the year explicitly to 1996.

From what I understand that issue is also related to GPS week number
rollover problems, and all of the clocks I know of that experienced
the issue are using Trimble GPS receivers...

The issue does not seem to affect all of the True Time clocks, but
then TrueTime seems to have used a number of different GPS receivers
and a number of different vintage Trimble units too.
