				  The Russian Schools Bid    .... and the Winner Was . . 
				. 
				
				 
				 
				 Introduction As I described on the MTX 
				About page, prior to being put into Administration, Memotech 
				was competing for the contract to place computers in some 64,000 
				Russian schools. Unfortunately for Memotech, they did not win 
				the contract and lost out to an MSX computer - to quote
				Wikipedia, 
				"the Soviets decided .... to acquire MSX computers from a 
				company in South Korea". [Subsequent to my writing of this article, Wikipedia has been 
				updated to the remove the reference to South Korea and identify 
				the chosen company as Yamaha - maybe they found the information 
				here :-)   ] I originally took the Wikipedia statement to mean that the 
				computers were manufactured by a South Korean company, guessing 
				that it might have been
				Samsung or
				Daewoo.  I now 
				know that my initial reading of the Wikipedia article was 
				wrong, while the deal may indeed have been brokered by a South 
				Korean company, perhaps with steel and oil interests (Hyundai 
				maybe?), the MSX computers that were supplied were initially 
				the export version of the 
				Yamaha 
				YIS503IIR (MSX-1). Each computer was fitted with a side-slot, 
				serial network adapter, that allowed the computers to be 
				networked. A number of Student computers would be networked with 
				one computer in "Teacher" mode. Once I established this independently of Wikipedia, I then 
				found confirmation in 
				this Wikipedia article, which specifically mentions the 
				Russian MSX. The "КУВТ" logo that you can see on the YIS503IIR 
				in the photo stands for "Class of Teaching Computing Equipment". A later class of "КУВТ" machines was 
				used, called "КУВТ-2", which used the 
				Yamaha YIS503IIIR (MSX-2). At that stage, a typical classroom 
				setup would consist of a Yamaha YIS805/128R (MSX2) "Teacher's 
				Computer" and 9 to 15 
				student terminals, YIS503IIIR (MSX2) without disk drives. The "КУВТ-2" 
				class system was supplied with network-enabled MSX-DOS and CP/M. The Russian MSX 
				Wikipedia page provides more detail of the use of MSX 
				computers in schools, a small section is quoted below - courtesy 
				of Google Translate with a little bit of grammatical editing  
				:- "First it was the export version of the Japanese company 
				Yamaha's computers - Model YIS-503 and 805, specifically 
				designed to supply the Soviet Union (it had a keyboard with 
				Russian characters). Classes on the basis of these computers are 
				called Yamaha KUVT. Later in the 80's, for the same purposes, 
				the Korean company Daewoo supplied computers - models CPC-300E 
				and CPC-400. They had Russian characters on the keyboard and a 
				normal one, not export, models. Toshiba also supplied 
				MSX-compatible computers in the USSR. In addition, there were 
				also Russian versions of the Japanese PC Sony HB-F9P and Sanyo 
				MPC-2300 but it is not known whether they were used in schools 
				or delivered for other purposes. Another model of the company 
				Sony, HB-G900P, used aboard the
				Mir 
				space station." So, although a Korean company did supply MSX computers to 
				Russia, they were not the first to do so. There is a very interesting page by a Russian MSX school 
				computer user
				here.
