| Want to gauge demand for pc-jamma bridge |

Can you still get the original finger boards? |

Yeah, they're just ISA edge connectors. My thinking here would be to do it one of two ways: Cheap(3 connections): USB-> jamma edge connector for IO Sound jack for unamplified sound -> on-board amp for audio Post connector for video or a VGA port for video This puts everything on the machine in use. You have to have a sound card and a video card that can output. Pricey(1 connection) USB connector to a board with sound/video/IO with the audio amp and a video converter w/a breakout connector for VGA. The cost here is the big one. I'm thinking that it'd be a bit more than the JPAC but it'd offer more features. |

I think you're 10 years too late. Fewer CRTs every year and they've gotten rare in the Project section here. Anyone that can figure out how to use your board can also use a JPAC. I share many of your sentiments about that product but I recall it used to be considerably more expensive and it's $59 these days. You really think you can squeeze out enough profit margin? Very easy to overestimate demand in this hobby. |

If you think the JPAC is expensive and doesn't do enough video processing for the money, I kinda wonder what you think you're going to do with this design... Video scalers aren't exactly the simplest things. Decent performance USB video is also not the cheapest thing in the world, but at least "standard res" is low enough that you can (probably) do it with only high-speed USB 2.0 and don't have to go to super-speed USB 3. IIRC, Andy sells a little audio/speaker amp that pairs with the JPAC nicely. A lot of later cabinets had non-standard stereo or line-level audio with amps built into the cabinet, so I think that's a good compromise. As to the video amp, yeah, it's not the greatest thing in the world. Again, cost is a factor, especially in the relatively limited volume these things are made owing to the declining popularity of standard res CRT arcade monitors (most VGA-capable ones don't need an amp at all - they just plug straight into a PC) and general declining popularity of even JAMMA. The Minimaid IO has a super nice video amp, but the amplifier on that thing would be cost prohibitive on something like a JPAC (a Minimaid IO will run you about $300). Also, they're not actually ISA edge connectors. The pad pitch is 0.156", whereas ISA was 0.1". If you're doing a custom PCB, this isn't a problem of course. |
