The big problem with 68-50 pin adapters is there are two kinds. Good and
bad. The good one have resisters on the ununsed pins. The bad ones
don't. Obviously the good ones cost a bit more. The bad one's can work
if you have only 8-bit devices and if you get lucky and the adapter
correctly senses that the data bus is only 8-bits or if you manually
configure the bus for 8-bits. Otherwise, the result is al kinds of
strange, often intermittent, problems.
