<>No, I'm not sure. It's been a long time. However that's the
resolutions given in the manual for the 1350 and
in the HP 1980 and 1982 catalogs. Probably they are just rounding it
off. The manual does mention the X=1022,
Y=1023 max values for a plot absolute command.
I looked in my HP1350 manual, and it's inconsistant. At one point it
claims the resolution is 1022*1023, at another place it gives the range
of parameters to the plot command as 0-1022 and 0-1023. Personally, I
believe the latter, there are good hardware reasons why that's the case.
