Th F381 is avavailable from Unicorn Electronics, the F382 probably not.
But the datasheet shows the detailed logic schematic, so it could easily
be emulated with a cheap CPLD (maybe even the complete 381/382 ALU core
will fit into a single CPLD), and maybe the F382 even fits into a GAL
circuit. CPLD might be a better choice for speed reasons, obviously.
