Thanks Colin - while it always feels better to 'Buy British', on the strength of your review it would seem that the PetDiskMax is both cheaper - even accounting for postage from the USA - and more fully featured. Going on what you now know I imagine you probably would have chosen the PetDiskMax in the first place, but therein lies the value of your summary - it helps anyone following to make a more informed first choice.

Did you notice the throwaway comment by 'GaryC' over on VCFED that he has made a Commodore disc substitute using an Arduino Mega and 'just wires'? I didn't get the impression that he has put it into the public arena. In theory you need some hardware level shifting between GPIB lines and any conventional data / control lines, and that is exactly the purpose of those awkward to get MC3446 buffer ICs.
