It's gotten worse.  There are few true parity SIMMs being sold these days.
Almost all of the "parity" SIMMs that I have seen in the big computer
places around the Bay Area are non parity SIMMs with a parity generator.
It really sucks when your mother board uses the opposite parity.....

At least the BIOS on most mother boards these days can be configured
to ignore the parity.  This allows one to use non parity SIMMs.
