Really? Do you have a citation? All of the information I've seen is
that LINCtape was invented for the LINC, and modified into
Microtape/DECtape by DEC for their machines, so I wouldn't think one
could really say that it was invented for the PDP-4. I suppose one
could say that the relatively minor differences between LINCtape and
Microtape/DECtape (mostly to support reverse transfers) were invented
for the PDP-4, if that was in fact the first DEC machine to use it, and
I'm not entirely convinced of that.
