Unfortunately I don't believe there are any options currently on the market. The two choices were the Drakware adapter and this older PIC based adapter that occasionally appeared on eBay (but is no longer listed).

I would either endeavor to find a used version of one of those -- which will be difficult -- or to find an original Indigo (or earlier) keyboard and mouse, which might be slightly easier to locate but still not very readily available, and much more expensive.

If they are not going to make this adapter anymore, they must share the project with the community so we can build our own!

Regarding the schematics, whenever you see a 5V or GND connection (or any other commonly named stub connection), anything with the same label is generally considered to be interconnected.

Your choice of oscillator seems to match up with the original design, just being a TTL/CMOS 10 MHz clock source.

One piece of advice especially since the board has a lot of space on it currently: I would try to place all components on one side. Doing so will ease assembly or open up more assembly options. It's harder to reflow boards that have surface mount components on both sides, for example.

Thanks, finish the redesign....
