A quick overview of the small family of consoles that call themselves the HE System: the PC Engine, Core Grafx I and II and the PC Engine LT. And when I say small I mean size not number!! There's a load more but I don't have them - Turbografx, Turbo Duo, PC Engine Duo, Duo R and Duo-RX and the handhelds PC Engine GT (see my other video) and Turbo Express (same but works with Turbo Chips). Oh and the PC Engine Shuttle, which for some reason didn't have the important expansion bus for connection to a CD ROM system...we could have had yet another CD ROM adaptor..oh well!!
