G'day Lou and Roger,
Have a look at the following link:

I guess that the original designers thought that 2^10 = 1042 was a sufficiently large number to cater for the useful life of the unit.
The 3.00 firmware versions date from around 1997, so by allowing for the 1024 figure to be subtracted after December 1997, they thought that another 20 years or so would be sufficient.
What were you doing in 1980 when this all kicked off? I was programming great circle maps and satellite tracking on an Apple 2 with cassette tape software and data saving! How time flies when you are having fun!
I gather there are possible firmware/software fixes, but frankly, I usually know the date (no Alzeimers yet!) so am more concerned that the 10MHz oscillator is being disciplined and the grid square and time are OK.
Cheers
