Cool. Could you probably check and comment those SuperPET disks on funet, and 
if yours are different, upload yours as well?

Do you need different (6809) ROMs for the different versions of the
language disks?

And/or scan the manuals?

Do you _need_ a double drive disk drive (like 8050/8250)? Or can you work 
on a single drive disk drive (SFD1001, 2031)?

I only heard the name "Computhink" in relation to a disk drive.
But the latter seems indeed to be a SuperPET expansion board.
Could you please check whether the ROMs on the board are the 
same as those on funet?
