FDC will not be added in the current revision of the project. It is already on my list of the future upgrades. It is quite possible that I'll remove printer...

I am open for suggestions for modifying TDC-600 or similar FDC. I was planning to build one for my system anyway. Relocating FDC registers elsewhere would require modifications to the...
