Specifications
The HB-G900AP is a MSX2 with a Z80A from Sharp (LH0080A) or NEC (uPD780C) and an MSX-Engine S1985 from Yamaha.
The architecture is similar to the HB-F700. The RAM is located in secondary slot 3-0. It can be upgraded to 1024kB by adding the same RAM type to the reserved empty locations.
The optional AV creator HBI-900 interface seems to be replacing the Videotizer (HBI-G900), a simplified interface to digitize images and have superimpose abilities for the European market.
