Back in the 1980's, the entire industry's TTL, at least in the DIP packages, became buggy due to ground bounce.
At a minisupercomputer startup called Multiflow, we were trying to ship large machines with thousands of FAST
and Advanced Schottky TTL chips that were all screwed up because of the lead inductance inside the packages.
We eventually discovered that 22V10's were properly designed, didn't suffer much if any ground bounce, and
could be programmed to do a lot of what the entire rest of the TTL line did. So if you look inside any Multiflow
machines (think museums here) you'll see a lot of those 22V10's. Not to mention you could fix design flaws
after the fact, which otherwise required wires tack-soldered to the PCB's.

The Micronix motherboard was all ∗through-hole∗ 22V10 PALs. I counted like 140
of them (other motherboards used chip sets from Chips and Technologies). The
motherboard alone (no processor) pulled 34A at +5V. I paid like $299 for a Cyrix
387 math co-processor and this was "a great deal". Ah, the good old days.....
