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?? 73 Glenn WB4UIV At 12:04 PM 3/24/2009, you wrote: >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. > >Corby Dawson >____________________________________________________________ >Click to compare mortgage rates.
