I also want to thank you for this information. I had asked many people on here to help me out and one is suppose to get back to me, so i'll have to tell him that I received the info.
This is very good news, now I can explore this item a little more closely.
Thanks to you!

Also, the Y2K problem can be easily solved by 'back dating' the device to a year prior to 2000 that has the same date and sky view. Calendars repeat their calendar dates roughly every 6-11 years, but depending on the "Leap" years it can vary every 28 years.
This is how the Y2K problem was immediately solved prior to 2000 before the roll over and to give engineers and software developers a way to solve the problem by swapping out components that could handle a four digit year function.
To do this easily, you can open any sky globe software and back date the view until it matches the same view you have now.
To give you a start, today date 02-06-2020 would match up to 02-60-1992...28 years ago...because it is a leap year.
Verify on your personal Planetarium software, these older Y2K (last millennium) devices can still be useful.
And because the north polar procession is only 1 degree every 76 years, or the span of an average human life, it should remain pretty accurate within your normal life span as well!
The only real problem with this is planet location. This would and cannot find planets ever again until a different Eprom is burned and the Y2K could be projected beyond that date.
No changing of the date can fix that.
Clear eye's and open skies (or is that the other way around.).
