I'm Pretty Darn Sure the geometries were the same between the ST251
and the ST251-1. In fact I've used them interchangeably in MicroVAX
systems. The idea of replacing an ST251 with an ST251-1 to increase
performance was an old trick that circulated around my local gang of
DECheads about 12 years ago.
