I'm not sure the 8259 is being made anymore. Jameco in the US lists them, but I
don't know how many they have. www.jameco.com

Looks like maybe Oki Semiconductor might still make them.

I found this with a Google search with "8259 Priority Interrupt Controller".
There's way more stuff so do a search and see what you can find. Good luck.

Oki do still make them in a range of packages, I've recently used it in
a design.

That's really sad.  It was a buggy, obsolete piece-o-shit 25
years ago.

I'm not sure what the reasoning behind this choice is.  But if it's not set
in stone you could consider using a CPLD to provide the functionality you
require.

If need only one or a couple , look for old 286/386 boards wasted, they have
two
8259.
Desolder with a hot-air gun.
