Some time ago I found an old Brose ASCII keyboard from Germany (post some more about this later), which I want to use with my Apple-1 build. I thought it was smart to test it in isolation before hooking it up to an Apple-1 or ][. As a software guy I am quite new to electronics. So I came up with a design of an ASCII Keyboard Tester / breakout board. Maybe it has been done before, but I thought it was a good excercise for me anyway.
I tested the 8 ASCII leds setup on a breadboard and it works great. During the design I added connectors for the Apple-1 and Apple ][ keyboard and test leds for Clear and Reset. For these two leds I am not sure if I wired them correctly, maybe they should be the other way around?
Here are the schematics, looking forward hearing what you guys think of it. I think I will make a pcb of it as well.
