It was suggested to me just today to try entering the old Y2K impaired Tamaya NC-77 almanac function using the current year minus 1900 to get reasonably good data out of it. I will be trying this on some sights to see how accurate the Sun and Aries values compare to USNO.
I had been using the Kolbe LTA quad values with success to correct the NC-77 years 1996 through 1999 with good success. If this other method holds up then it will revitalize the great vintage Tamaya NC-77 to it's full function.
