I have been thinking about writing a post about the BMon system by Eyetech but I have refused to because the system is so complicated. But to make it easy to explain, it is a monitor switcher that switches between CGFX (CyberGraphX) and AGA screenmodes so that output from scandoubler and output from RTG-graphics board can be viewed on a single monitor.

Here is another shot of the Eyetech Bmon keyboard switcher for the Amiga 1200 frontside
This little device here is a rare component of the BMon system. It fits the Amiga 1200 motherboard on the little chip that usually holds a PC-keyboard adapter (IIRC) and lets the user switch between graphics card and AGA by pressing a button on the keyboard (I think it was the “*” key). There was also the AMon component, it was the automatic monitor switching part in the BMon saga, and then there was the manual switch part, that is the most known I think.

Anyway this is a neat little rare Amiga hardware part that is essential if you are building a super Amiga PPC/CGFX system in an A1200 desktop.

And here is the backside of the Eyetech A1200 switcher
