The Memotech MTX Series |
|
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.
