Which raises a question I've been meaning to ask. Seems like a 4 layer board with gold fingers would
work - the few
boards
I've handled seemed pretty thick, however.
I'm guessing the
thickness
needs to be correct.
Small variations shouldn't matter. I've not noticed any Unibus boards
being abnormally thick.
I have not (yet) looked at a unibus card schematic -
would be it hard
to
create a bus master IDE interface?
Is a unibus controller a relatively straight forward TTL design ?
Dunno about the DMA -- probably not hard -- but the rest is
straightforward.
And, if I did manage to create a realiable IDE
interface, would
anyone
else want one?
For low enough cost, yes, me!
