Russian Mk-61 - Chuck - 11-20-2007 Finally recieved my Electronica Mk-61 from the Ukraine today. It came with power cord, registration card, case, box, manual (in Russian) and an 18in x 24in schematic of the electronics inside (let's see HP offer that.) It still had the plastic film protector over the screen. I should have left it on, but it was quite cloudy and hard to see through. After removing the film it looks brand new. However, my first calcution was 6^3 which produces 215.99994. Oh well, I guess that was close enough for 1981. All in all, it's a nice little RPN calculator for the collection. (now I need to have my calc student from the Ukraine translate the buttons for me.)

Re: Russian imprecision - db (martinez, ca.) - 11-20-2007 Another example of "close but no cigarski" is the MC1103 Re: Russian imprecision - Reth - 11-20-2007 now show us the mexican one ...
No batteries needed... - Thor Lansen - 11-20-2007 Long before HP, Electronica, and others the Mayans had invented a computer. Read this article: D'Alto, Nick. Odyssey, Mar2005, Vol. 14 Issue 3, p34-48.
The article talks about a "computer" invented by the Mayans.

Re: No batteries needed... - Chuck - 11-20-2007 Good article, db. Thanks for pointing the way to it. Scratch that, I see them now. ;)

Re: Russian Mk-61 - hpnut - 11-22-2007 Hi, I received my MK-61 from the Ukraine yesterday, airfreight from Ukraine was via Russian Federation (i saw the postmarks on the box), all in 12 days to Malaysia! In the box: MK-61, power adapter, slip case. The calculator was advertised as being fully tested but to my disappointment, there were two serious defects: 1-could only power up on AC. despite cleaning the light corrosion in the battery terminal, couldn't get it to work on battery. 2-the button '8' when pressed shows the figure '5' which actually is 5. I confirmed this by pressing '8' ENTER '8' X shows 25 and also '8' F X^2 again shows 25! no, it's not a case of faulty display. 64 square root correctly displays 8. I'm thinking of returning the calculator back to the vendor in exchange for a working calculator. overall, quite a nice calculator, except for the horrible plastic buttons - worse than el cheapo Casios :-)

Re: Russian Mk-61 - hpnut - 11-27-2007 The vendor has agreed to give me a working calculator. In case anyone is considering buying from this person, I can vouch that he (or she?) is a genuine eBayer. the vendor is sovdepia, based in the Ukraine.
btw, Katie Wass at http://www.wass.net/manuals/ has kindly put up the MK-61 manual on my request. of course, it's in Russian but the examples are universal. thanks, Katie :-) Edited: 27 Nov 2007, 9:57 p.m.
