I forgot if these things where called BMON, AMON or UMON, but it is a monitor switcher that Eyetech used to sell and make.

It has a switch and you can connect your CV64-3D or CVPPC graphcs card to the switcher. The switcher has pinouts for another display output, I used these with a DCE scandoubler/Flickerfixer, the cable fits without adapter. With a modern scandoubler I think you have to make an adapter to fit the BMON.

So when you have the device hooked up to graphics card and scandoubler you can flip the switch and can select which output to see on the monitor, either RTG-graphics or native AGA graphics output. How nice, now you do not have to keep that old 1084 monitor just to go to early startup anymore!

BMON #1 setup

This is a BMON setup in nice condition. It has a problem that needs to be fixed before working again though. Take a look at the second picture!

It is broken

Do you see that resistor I have marked in the red ring with the arrow pointing to it. You see it is a bit darkened?

The metal switch accidently hit the Elbox tower I had it in while it was hanging from the cables, so something happened when it hit ground with the result this small resistor became destroyed. I tried it with another switch and it worked, so if you replace this small part I think it will work.

BMON #2 setup

Here is the next BMON Amiga monitor switch, it is also broken, but I think easy to fix also.

Guess what is broken? -The switch is missing the switch lol

Yes, the switch is missing

This is just a standard switch with three poles so I guess it is easy to replace it.

These devices can sell for as much as 50-60 euros so these are a f”n steal (I know it) so dont go sell them on AmiBay or eBay for profit.
