Port B bit 0 as output on PA4 soic-20 pkg

I can't make it drive a ULN2003 (~170uA).

Tried 2 chips, both same syndrome.

Works fine as input, with pull up or not.

Same circuitry using bits 0-5 as outputs, 1-5 behave fine.

With 15+ years using 68xxx08 chips, I think I found my 1st errata.

Am I missing something here?  TNX K.Sargent
