[WTS] Nikko PC-70100

I would like to sell Nikko PC-70100 (images) (wiki). It is an extremely rare one-of-a-kind handmade MSX with high historicity. Specs: MSX1, NTSC 16 kb RAM, 1 slot, DC 9V center positive 2.5 mm power. I recommend feeding it with a smartphone battery, USB 5V-to-9V converter and if necessary polarity converter. and 2.1 mm-to-2.5 mm converter (I can prepurchase the converters). SD Mapper is the recommended storage device. The estimated shipping is the 2.5 kg rate here.
Please name your price.
