And another one to make you nervous. The MSX2 was a lovechild of Microsoft and the ASCII Coproration and was conceived in June 1983. The purpose of the machine and architecture was to somehow unify different standards among various home computing system manufacturers of the period. Imagine: Like VHS but for home computers. 

The MSX later became popular especially in Japan, where around 5 million MSX-based units were sold. Holy Moly. Today of course, very few machines are to be found in working condition.

Sergey Kiselev to the rescue. My hero! The CPU is a a Z80. Garnish it with numerous 74XX series logic chips, add a little bit of time to the mix and profit. When you eventually make it, you'll be rewarded with a series of games that were initially developed only for MSX (I only say Metal Gear). 

Have a look.
