Yeah, 1989 was way too late for advanced 8-bit micro. Also, several design flows. For graphics chip stealing CPU cycles, they could have done something like ST has, having memory running on double CPU freq. so that both graphics and CPU can access memory bus on alternative RAM cycles. Also, lack of any hardware support for graphics means that the most attractive mode for games (256x192x 16 col.) is practically unusable for any scrolling games as 6 mhz CPU stand no chances smoothly moving 24kb framebuffer.
what is the story behind the intro music?
Yes
