Not just the Eastern block, or Far East...
 
Remember the Plessey SL600 series of communicaiton signal processing chips?
 
Originaly in 8 and 10 pin TO5 can's, later in plastic DIP's, as the 1600 series.
 
Sadly missed here by many these days.

Folks;

Writing as someone in the US, I keep seeing interesting available 
electronic components coming out of Russia, the Ukraine, etc. on 
eBay. I rather suspect there are a lot more types available than what 
I see there.

Can anyone recommend any web sites where there might be spec sheets, 
catalogs, parts lists, and places to order these unusual (for the US) 
parts?

As one example, you can easily get Russian NIXIE tube driver IC's; 
I'm wondering if there are any other interesting functions that might 
have either never existed in the west (or which disappeared a long 
time ago), and which might be fun to experiment with.

It seems to me there is a whole other world out there that might be 
fun to explore.

Logically, this would also segue into eastern test equipment...do the 
Russians make cesium clocks that might be cheaper than HP's?  If so, 
a source of repair parts would be in order.

Any suggestions greatly appreciated.

Sincerely;

Tom Frank, KA2CDK

P.S. - as an aside, I know there is an entire selection of IC's 
available in China that are not available in the US expect under the 
most unusual circumstances...they are optimized for toys (think 
Mattel or Hasbro), and the documentation on them is very limited.
