I have never seen something like that, WTH guys its a logic buffer
buffer connected to a dip plug and 8 bits of the bus

if its a music card you would have to bit bang the crap out of the bus
which is 8 times as bad as bit banging a single cpu register for not
much gain (maybe some decent gain for the time)
