Omega computer : USB keyboard interface.

A few weeks ago, I talked about Sergey Kiselev's MSX2 compatible processor board project. I have completed the assembly of a copy of this board. I like a lot the style of the result:

I equipped this board with the system, also MSX compatible, C-BIOS ver 0.29. The whole system works perfectly.

But, for the moment, I do not have a keyboard or cartridge to interact with the machine. Given the cost of building this type of material that uses original components, I decided to test the adaptation of a standard USB type keyboard instead.

I have therefore developed a small circuit which will take place in the keyboard connector of the Omega board and will directly provide an input for a USB keyboard:

The finished prototype should look like this:

I must also plan to use a ROM or FLASH cartridge in order to test some software applications. The MSX environment is increasingly dynamic. New games continue to be produced. 2021 looks promising! 

I have some ideas to try to improve the performance of this type of material ...
