A few months ago I picked up an old video arcade machine off the side of the road. It was a Dodge City video poker machine from the early 90s made by Merit Industries. The cabinet was water damaged and I couldn't really use it for anything nor could I find anyone who wanted it, so I scrapped it and saved the interesting bits like the boards and the monitor. One thing that I think is interesting about the main board is it seems to be set up with all the basic ICs for an MSX system. The main processor is a z80 with two PIO's, an Intel 8255, two Yamaha v9938 video processors and a Yamaha ym2149f audio chip. I think it has 64k of RAM based on the 8 IN41464P ICs, plus spots for four more chips. It's got three PROMS in place with room for 5 more. Now I have no idea of what the pin out for the 65-pin connector is so I don't know if it would be possible to interface things like mass storage or a keyboard. Might I be able to pop in a monitor for BASIC ROM and go somewhere? I don't know if I could find a schematic for an anywhere. I'm just wondering if this is something to play with or something to save for components. Thoughts?
