I happen to have a massbus adapter and the cabling with terminator for my 11/750, but I never came across any massbus peripherals. Considering the price back then and the size for these, they seem nowadays quite rare, which is a real pity.  
Anybody knows if there was conversion kit to equip CDC 9762 and 9766 type SMD drives into MASSBUS drives much like the TU81 could be turned into a TA81 (SDI)?
