and program whatever you want the character set to be (i.e. hook or no
hook on 6s, etc. )?
That's where we started. Tony wanted to see what the minimum in
combinatorial logic would be. To date, I've not seen a solution that
doesn't use decoders or demuxes, just AND OR and NOT elements.
Anyone care to give that a crack and see what the optimal case is
using SSI TTL--say, nothing more complex than a 7486?
