HPA-1 Clone Intellectual Property

Hi, I would send a PM to NP, but that doesn't seem to be an option.

Out of courtesy and respect, I wanted to check if there are any guidelines and/or objections with respect to my releasing PC design files for my version of Jeff Young's reverse-engineered HPA-1 schematic. I don't think there's a legal issue, but I don't want make a problem, e.g., inadvertently doing R&D for eBay cloners.

Jeff's Kicad files have been in the wild for a long time with no apparent harm, but I want to double-check.

My only intent is to give something back to the community.

Thanks.
