how many turbo-r machines are sold ?

Fun fact (not sure if I've told this already): back in 1997 my girlfriend (now wife) found a brand new Turbo-R for sale in an electronics shop in Osaka. Unfortunately I wasn't able to afford it back then, so I went for the used one they also had for sale. That one is my main MSX unit nowadays.
