Yup, the first two or three 3016's our college bought were fine, so we
bought ten (IIRC) more, and those ones came with added holes -- more

Or the early Commodore PET computers with holes
drilled through the pads for additional RAM chips. Of course, once again, nothing really
stopping a determined hardware hacker from bridging wires to the severed traces...
I have one of those - I wouldn't call them early - it was the "dynamic
PET" model that could take one or two rows of 4Kx1 or 16Kx1 DRAMs, so
long after the SRAM PETs (which I _would_ call early). If you bought
the 16K version, they sent you a board with a bunch of ~6mm holes
between the unused RAM spots.
