Still have my HP-41 around, and it's still my all
time favourite. I must
I've forgotten how many HP41s I currently own (!). About the only major
thing I am missing is the 'halfnut' HP41C (yes, it did exist, it's rare
because the only way to get one was to send an HP41C in for repair and
for HP to replace it with a new machine [1]). I even have an 'Bug 1' HP41C...
[1] I am still suprised them made it. The difference between a C and a
CV is, of course, the amount of user memory. and in the halfnut versions
the RAM is combined with the ROM and the display drivers in a hybrid
module. I would have thought it would have been more expensive for HP to
do a speecial production run of 'C' hybrid modules to use in
service-replacemetn calculators than just to send out a CV when an
unrepairable C cam in for repair. And yes, it is a different hybrid
module, it's not set by a link on the PCB or anything...
Anyway, I like the HP41. I've got quite a few modules, an MLDL box, port
extender, HPIL (and plotter, disk drive, tape drive, Thinkjet, etc), and
so on. And technical documentation, etc...
Mind you, I prefer the HPIL implementation on the HP71B (I have a few of
those, the FOrth/Assembler ROM, HP41 translator ROM, the full IDS
manuals, etc).
No, I am not
intersted in having machines on the shelf in original
condition. I want to be able to sue them, investigate them, and so on.
We think alike. :-)
