I have a bunch of them, although they're not NIB.
I also have some PC1360s,
I still have my PC1500 complete with printer/plotter, RS232 interface
_and Technical Manual_ :-), although personally I prefer the HP71 (and
yes, I do haev the complete IDS with schematics and ROM source code,
along with most of the HPIL prripherals, ROM modules, etc).
One day I must get a Sharp PC1350 to go with the manuals I have for it (3
manuals, User/programming, Technical Reference, and Service. The last I
suspect is not common).
