Off Topic. Dark Side wonderfull calculator



#6

Yes, I know, its not an HP.
I also know that people who loves HP models calls "Dark Side" to Texas Instruments.

Well, I readed about a wonderfull TI model in the 65-Notes Vol-3-NÂș-2 page 2.

Its a very very very unusual model.
I think is so rare that you can not find this model in www.datamath.org

Perhaps is more difficult to find than the TI-88 or HP XPander


... but...

here you are:

#7

Wow! Nice calc! Based on the same principles I use daily to compute mathematical totals, like my IQ, etc.!

Getting harder to start up, though,... especially in the mornings. It also keeps increasing it's weight.

I wonder if this one was obtained by a "five-fingered discount."

I plan to bid early and often....well, no more than I can count on one hand, anyway.

Michael


#8

Checked my Datamath Site - you are right: Not mentioned there.

BUT: No "=" key, seems to be an ealy HP ;-))

Greetings from the Dark Side, Joerg


#9

JAJAJA :-)) :-))

No =, but also not "ENTER" key... mmmm :-))

Perhaps not an TI nor an HP
I said it was a TI because I saw the machine at "65 Notes"... perhaps was wrong in the revue.
Maybe an National Semiconductor?
Maybe an TI prototype?

Greetings

Daniel


#10

Not binary, not octal, not decimal, not hexadecimal, but ....

a "funf-imal" base machine (?).
