Why bother? 6264 and 62256 chips are extremely common and much
more "standard". They go for a few dollars a tube all day long on
eBay. And, should you ever decide to "go that way" with a design,
they're also readily available in SMT packages.
Standard chips good. Weird chips from the PC world, bad.
