Wow, for that amount (331.000 yen) I have 2 Turbo-R's (one boxed) and a lot of additional hardware! 
I hope the buyer will not sell it again as I don't know if people will pay this amount again... probably it's a collector and not an user. Too bad not using it... Just be glad you didn't buy it, as you also had to pay import duties 
It could also be a speculator. Think about it: at least two people wanted it badly enough to bid 330,000 yen. Save the photos, because if this was a speculator then we may see this machine again in an auction somewhere with a starting price higher than what he paid today.
Personally, I really hope the machine went to someone who will actually use it.
True... Same goes for me, although I have one for spare in case the other one dies...
When my Turbo R dies, I won't have a backup. 
I'll have to try and repair it myself or with a friend's help.
Though if it really were to truly die and not be something that could be repaired, wasn't someone here SD-SNATCHER perhaps that was talking about the need of sacrificing a R800 chip in order to fully tear it down to see how it was made? In that process we could finally see how an R800 chip was put together and perhaps it could then be duplicated in other MSX projects such as MSX ARM or the latest version of a 1-Chip MSX.

Yes, and if you find a Turbo-R, you don't have to do much modifications anymore like 2+ / turbo / RAM / DOS2 and MSX-MUSIC but probably only the powersupply and optional beltless drive. So, the mainboard looks very neat without extra wires
