I have been wanting to collect a Europlus as it's one of the few Apples I don't have and it's also the first Apple I used (my grandfather had one and it was nicely kitted out with an 80 column card, serial and parallel cards and a Z80 softcard).
They are very expensive on ebay and I would have to have it sent to Australia from UK or Europe as I do not see any in Australia for sale. However, I met another collector locally who has a nice Europlus case with keyboard that he can sell to me.
Therefore, if anyone has a motherboard or power supply (non working is fine and perhaps even preferable if the price is right) I would be keen to buy. And as a bonus, shipping to Australia (if it is not already here) is cheaper than a whole system.
