a "1000" in HP's docs. (The A series are single board computers,

Thanks for the tip Stan! I know absolutely nothing about the A series. I
didn't know if they were also part of the 1000 line. I appreciate your
correction. One remarkable characteristic about the 2100/21MX line is that
each sucessive machine released supported full backwards instruction set
compatibility. For instance, the 21MX M, E, and F series all are fully
backwards compatible with the 2100 instruction set (except for timing
dependent loops). Do you know if the A series also supports the 2100
instruction set?
I'm still in the process of sorting through dozens
of boxes of HP manuals,
but I've noticed at least two boxes of HP 1000 manuals of various kinds
(including some maint/diag manuals). I'll post more later, when I've
figured out more.
Of course, I'd love to hear what 1000 manuals you might have!
