[...] the emails and phone number are no longer in service.
They have to be, so you can always bash them through the whois, as they loose the right to their domain, if they're not reachable through their contact details for two weeks or so IIRC .
In any case, I just send them an email on their regular addy - I'll tell you if I get any response.
So i moved on and looking to see if anyone on here has a mark 3 or something very close that uses the 16f877 chip.
Why does it have to be a 16F877 (It's a dinosaur)?
Take a look at some kick-ass 32bit (Arduino compatible) PIC boards http://www.digilentinc.com/Products/Catalog.cfm?NavPath=2,892&Cat=18
It's lightyears ahead of anything carrying a 16F877 and the smallest one, the Uno32 is even cheaper than the MarkIII (and running circles around it).
