Great kit, great support.
For OtterX 8-Bit Retro Computer
I was very pleased with this kit after I got it working.
I initially had problems with an unresponsive keyboard. Help via Discord was almost immediately forthcoming, so I was very impressed with the support.
The docs were rather sparse, and building it was a little daunting until I discovered the BOM link here on Tindie. This is an interactive web page that makes it easy to get the parts in the right place.
