MSX2/2+/Turbo-R
The MSX2 was released in 1985, and this was, and still is, a great computer system. Basically it was a super-charged MSX1, here are some of the specs... The main RAM was at least 64KB, altho a Sony model got it up to 256KB, which was internally expandable to 4MB with the Memory Mapper system. The Video Display Processor was a Yamaha V9938, with 128KB video RAM in most machines, and most MSX2 machines had at least one disk drive, 360KB or 720KB 3.5".

The MSX2+ was released in 1988 in Japan and Holland(and probably in some other European countries), due to Microsoft leaving the project. This was really when the MSX machines started losing steam. This made a few upgrades from the MSX2, but not really enough to go into great detail here.

After the MSX scene was slowly fading away, ASCII's last-ditch effort was the MSX Turbo-R. It never caught on though, all the top game designers were leaving MSX for Nintendo, and Panasonic was the only company that ever produced any Turbo-R machines. Which is too bad, the video display processor was just a step below the 3DO's (awful system, but it did had great graphics for the time). In fact, the chip that the 3DO used was originally meant for a MSX3 which unfortunately, we never saw. Though some companies now are making carts you can buy for your MSX that contains a chip like the one used in the 3DO. Very few games were released for Turbo-R, but some of them are classics, such as Microcabin's sci-fi RPG "Illusion City."
