Although I have to wonder how the makers of the mostly finished Kiwi 68008 board get around the ROHS regulations (they use old components like V9990 video display processors).
I don't know if a V9990 contains hazardous substances, if it does and they sell it as a complete system then they may face problems (if they are caught)
"It is permissible to place on the market spare parts - containing the hazardous substances - for the repair of old equipment (if the latter was put on the market before 1st July 2006). But it is not permissible to repair new equipment (put on the market after 1st July 2006) with spare parts containing hazardous substances."
The more interesting example is the amiga reloaded. Arguing that is a spare part for repairing an old amiga would be a stretch and it's all surface mounted so can't realistically be sold as a kit.
Fortunately the two new C64 reloaded (if they ever arrive) should be fine.
Reimbursement for personal expenses that not incurred by a business activity are hardly the purview of a regulatory agency.
And this is not a business.
They provide a product for a fee, how is that not a business? It may not be a profitable business, but if ROHS cared about that then every single manufacturer would figure out how to not be profitable. "I poisoned 20 million people today, but I shouldn't be held responsible because I was only reimbursed for my personal expenses".
The board doesn't have a ROHS problem anyway.
