Alu schematics use obsolete chip

[jf0772256]

I have been trying to build the alu from schematic, the chips 74xxx382 alu function chips are considered obsolete and I was unable to find an equivalent chip, do you know of a production chip that can replace it?

A firm in Switzerland currently (Feb. 2023) has these rare ALU chips [SN74LS382] in stock: https://shop.griederbauteile.ch/product_info.php?cPath=25_27_119&products_id=6610 . Look carefully at the shipping costs for foreign orders, though. I have acquired a few for a project derived from the James Bates 8 bit CPU. It should also be possible to emulate these using an 8k ROM (say 28C64).
