@azonenberg @kenshirriff The question I had was, if those 16 entries had been specified correctly in the input to the code that derived the PLA equations ... would that still have fit in the same size (112 rows) of PLA? If not, you'd need more than a FIB to fix this.

@acsawdey @kenshirriff Yep, that's exactly the question. How extensive the edits are.

@azonenberg @kenshirriff hadn't considered that, yeah maybe it fits but you have to change some large percentage of the logic terms.

@acsawdey @kenshirriff The other thing is, you can't FIB a transistor into being.

It's easy (ish) to FIB a metal rom in either direction, and to delete a transistor in an active-programmed ROM.

But you can't make new ones.
