Or the epoxy or cut pins, etc., on the iOpener.
Some of the "fixes" did make it difficult to mod the iOpener, but in
the end, none were successful in keeping out the determined geeks.
It did take a while to pick that epoxy out, but it can be done. ;-)

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.
For mine, I could run all the missing wires and drop in 8x 4116 chips,
but I happen to have a CPU-socket ROM/RAM adapter, so I can just
supply the missing memory with one SRAM and get multiple ROM versions
for "free".

That sounds like a trick a PC manufacturer would use to avoid honouring
a warranty repair request -- leave a few unstuffed components on a
thru-hole board, then declare the warranty void because "extra holes
were drilled into the board".
Put it this way: given the "fun" I've had with component suppliers and
"warranties", it wouldn't surprise me in the least to hear of someone
doing that.

I also remember reading of a board-swap upgrade (may have been TRS80 M3
to M4) where you were supposed to destroy the old board by drilling a
hole in it. Point is, they didn't tell you where to drill the hole, and
it was possible to do it in an spot that was just ground plane on both
sides. Hmmm...

I am sure I haev seen at least one warrenty that was technically void if
you tired ot use the product in the standard way. But I forget what it
was. Personally, I ignore warrenties. If the product really is defective
in maufacutre, then you don;t _need_ a warrenty in the UK. And most of
the time I take the view that if a company couldn't make it properly in
the first place, I am not going to trust them to repair it.
