Did they ever make a 2364 OTP EPROM

I've got a NEC PC-6006 RAM/ROM cartridge and found this page about it:

I'd love to find an EPROM solution for 8K, but it looks like 8K is pushing it about the number of pins.  I'm guessing maybe it was designed for mask ROM 2364, but I wonder what programmable solutions there are.

Motorola made some 8K EPROMs in a 24pin package: MCM68764 and MCM68766.

However, both are now as rare as hen's teeth and probably can't be programmed by any modern EPROM programmer.

Benta:
27C64 are still to be had.

But these won't fit into the 24 pin socket in the ROM cartridge the OP is referring to.

wraper:
You can make a PLCC32/DIP28 to DIP24 adaptor board for 2764.
