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.

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.
