I am trying to make all these boards work. I had a power supply for one and now it's gone. What can I use for the 15 vac that is needed to power it up

What happened to your power supply that is "gone"?
If you are talking about just getting 15 vac to the mpu board by itself here's one way to get that voltage. But I think the mpu also needs 5 vdc and maybe 12 vdc too. Do you have those voltages available?
Some doorbell transformers are made with an output 16 vac, that should be close enough to what you need. Just need to get one that has enough amps for your board. The higher the wattage (power) rating (also called the VA or VAR rating) the stronger the transformer is. I would think 1 or 2 amps (probably less) should do it but I don't know your board's amp requirements. The input side of the doorbell transformer connects to your 115/120 vac wall outlet. The output of the transformer will have 16 vac. Might be able to find one at your local hardware store and at home improvement stores (HomeDepot, Lowes, etc), places that sell doorbell parts and kits.
Some doorbell transformers are only 12 vac output, so watch out for those, I think they would be too low.
Here are some examples:

Thanks for the info. I said gone meaning it got took.

You've been a lot of help. Can you tell me why I cannot use a video converter front cga to vga? It works for cherry master but not for this.

Sorry to hear someone took the power supply you were using. In the shop I used to work in we'd sometimes have people "borrow" tools or equipment and not bring them back. We setup some cheap security cameras and that stopped the nonsense.
Not sure why the video converter doesn't work, but since there are different video formats maybe the CalOmega video signal is not compatible with the video converter. Sometimes the sync pulses are opposite from what the converter is expecting (i.e., the CalOmega sync pulses might be negative and the converter is expecting positive pulses, or vice versa). Or it might just be a pinout difference on the CalOmega video connector. Back when the CalOmega mpu board was designed and built they didn't have the same video standards we have today.
If you can get info on the monitor or monitor board that the CalOmega machine uses that might tell you what type of video signal it expects, and that would be the video signal the CalOmega mpu board outputs. If you have the schematic drawing for the CalOmega mpu it may show what pins the RGB video signals are on, as well as the sync pulses. Some mpu boards have a dipswitch setting that selects positive or negative sync, for use with different monitors. You might look into what the dipswitches on your mpu board do.

When you said "boards" in your first post what did you mean, do you have multiple. What revision are they?
