Right now, it is just a personal project with my wants and to suit my available tools and spare parts.
The block of power connectors is for powering auxiliary devices. Original intent was just to have a +5v connection for the Gonbes 8200 (GBS modded) to be powered for PCB repair. Then with some manual switching, I can pipe the video into a CRT for CRT repair and calibration. There is enough room on the board that I added extra taps for +5v and +12v to power what ever else might be needed: optical joysticks, analogue controls, small LCD screen. Designated test points are there to be used with clips for the probe.
The external controls use the 2x10 multi console pinout. I want to keep things compact, maybe even portable. So the idea is for me to use undamned USB controllers for external controls. Or
wire up some of my cheaper fightsticks for test bench purposes. Honestly, momentary switches should take care of 90% of inputs in a test bench scenario. External controls is a luxury or for extended testing.
Will be using this
speaker. I looked at other small speaker options out there, but mounting and size become difficult to solution. Not the best speaker in the world, but just need something for proof of audio working status in a test bench scenario. Fidelity isn't a consideration for the onboard speaker. Form factor and size is. There is a DPDT switch to output to an external speaker if needed.
Need a little help with attenuating the audio levels down for
this speaker.
