Ebay seller ”moogchild” has one for $59 in Spain. If you have to get one burned, there are some new ones if you can find somebody with the binary file and a ROM burner. The 4789 is a slightly newer EPROM version of the same chip if someone has a programmer that can do EPROM but not ROM.

So I pulled the key assigner, the NEC8049C 217 out of my working Polysix and popped it into the one that wasn't working and it works, sooooo now I've got to source a NEC8049C 217.  Anyone got any leads?
Thanks
Barry

Are you sure that you connected the cable from the keyboard to the
KLM366 in the right orientation?
