The fix proposed by Shostak for the AST Combo card in an XT sounds
risky to me.  I don't trust ANY flip-flop on the market from any one
manufacturer to consistently come up in a guaranteed state from date
code batch x to batch y.  Also, there are going to be people who will
ask for a 74LS112 from Signetics and be given whatever happens to be
in the bin at the local Radio Shaft or J-Random electronics store.

I'll look at one of the local IBMer's AST schematic and see if there
is a somewhat more guaranteed way of doing the fix.
