OT: Is his a real Red Dot? :-), Again


I could never imagine that a calculator that Sharp had the sale value.
I have one and I see no feature that makes it stand out from other calculators.

"I have a PC-1201 in mint condition.
It is a nice little device.
I struggled with programming it because I didn't have a manual but I eventually figured it out.
I paid three dollars for it back in 2005.
Perhaps I should hold it and wait for even more appreciation.
The bid of $607 does seema little high but I don't have any real insight as to the rarity o the PC-1201 or how many collectors are interested. I do have a HP-41CV in very good condition with manual, carrying case and carton that I purchased in 1998 for two dollars.
I also have a mint condition HP-41CX with manual, carrying case, and carton that I purchased in 1999 for five dollars.
How does the appreciation of those devices compare with that of the PC-1201? "

Good explanation for the green display and this one?

Well, some of my favorite calculators in my collection ARE Sharps. For some reason the sharp-edged metal accents of the Sharps are enticing, sometimes more-so than the brown plastic HP's that most here go ape over. And, the Sharps aren't all that bad of a calculator. Last week I acquired a Sharp 5500III Computer. Nice little machine for about 1/10 the price of any HP (okay, not any, but most.) Not sure if I'd go to the $200 plateau on one, but still I find them interesting.

I have a more advanced version of this calculator, the EL-9000. It's a great calculator, which cost about $120, circa 1988.

I wouldn't pay $200 for it though.
