This was added in on the current schematic.. But really as I am planning to adding buffers to place some other chips, I would assume the shifter MONO output is actually a digital one, and just switches between 0V & 5V ? So digital buffer should be okay here ?
This way we would save on there few parts not having to have basically a analogue buffer...

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~

Re: MONO output buffer thoughts
The Shifter's MONO output is digital and TTL level, yes. The SM124's input is rated for nominally 1Vpp, though. This is why you have the divider R32/R33 and the emitter follower in the Atari ST.
