The HX-10S is the first MSX computer released by Toshiba.

This machine was aimed at the Japanese market under the label 'Pasopia IQ' and available in black (K) and red (R) - see HX-10 series for the technical details. It lacks a printer interface. Toshiba sold the HX-P500 interface cartridge to connect to a printer.

Official price: ¥55,800.

The HX-10S has same board as the HX-10D. So it seems upgradable to 64kB quite easily. (See this thread for more info.)
