I purchased one of the landscape layout ones with the green display (MK 52). It came in good condition even though the packing wasn't all that great. Took a little less than 2 weeks to get to Oklahoma City. Mine came from Ukraine not Russia. It certainly isn't of the same quality of the hp machines. For example 2^3 comes out as 7.9999993 instead of 8. and it is X^Y not y^x I haven't played with it all that much so I can't say much more. The buttons don't have a very consistent feel. Some times they click sometimes not.

Hi Namir. We met at the San Jose confrence. I've bought six "red" RPNs from the former eastern block and traded for two more from Germany. One took 89 days to get here from Ukrane. One from Russia was broken but he took it back (i paid shipping back there). As Chris said; the quality of an hp (or Corvus or Heathkit or Privileg) is not there but they are RPN and quite original, although one is said to use an hp display. The packaging was adequate and although two were wrapped in twine they got here fine.
Did you ever see my little RPN collection? Thanks to Mike Davis, it's at

I bought an MK-61. It's identical to the MK-52 already mentioned except that it is in the traditional calculator shape and it does not have permanent storage. It takes mine a second or two to compute trig identities and as already mentioned it is a bit inaccurate at times. However, you have to consider that it came out in the mid 1980s using Soviet technology. I only payed $15 plus shipping from the Ukraine for mine and it arrived here in the US in 2 or 3 weeks. I don't use it from day to day but it is a neat calculator I play with from time to time. In my opninion, it was a good buy.
