The Yamaha YM2220 VDP



The Yamaha YM2220 is a Video Display Processor (VDP) compatible with the Texas Instruments TMS9918, used in some MSX1 computers manufactured by Yamaha. It is clocked at 10.7 MHz.

Since it comes in a 64 pin SDIP package, it is not pin-compatible with the TMS9918.

Although it's a MSX1 VDP, the color palette looks very similar to the MSX2 default color palette.


  • Package: 64 pin Shrink DIP (SDIP)
