What is Namco System 1 ?

The Namco system 1 boardset appeared around 1986 and supported some real classic games, such as Pacmania, Galaga'88, Dragon Spirit and SplatterHouse.

In my opinion this hardware is the pinnacle of 8bit board design. Featuring a total of THREE 6809 cpu's and a 63701 micro-controller. Video hardware was equally as cool with a 6 layer screen, 4 of which featured hardware scrolling, each layer could display 256 colours with a programmable 24bit palette - allowing for upto 16million colors. Basically 'kick-ass' by any standards.

The sound system used one of the CPUs, and the micro-controller for sampled waveform playback, it also had stereo sound provided by two Namco 8 channel custom sound chips and the excellent Yamaha YM2151 FM synth.


Here's a links to the JAS-SYS1.TXT instruction file. All questions about running the emulator should be in here. PLEASE READ THIS DOCUMENT BEFORE EMAILING ME QUESTIONS !
