Default Re: MK14 SN74S571 PROM Power reduction test

The problem was size - something like a PYE PFX or a Storno 4000 was already tightly packed with parts, so there wasn't really any room for a wide-bodied 24 pin or 28 pin EPROM in there. You only really had that luxury in mobile radios.

I forgot to say that Buzby couldn't have done that mod any more neatly, I was imagining bits of vero stuck on the underside of the PCB.
