16B keyboard is the same as the 12. Cord is on the KB with a male connector. Female is on the machine.
16B has the same main board as the 12 with 68K in the cage. Notice I use "main board" as technically the cage board was referred to as the motherboard in these machines.
>> The 6000 released in 1985 was a slightly enhanced 16B with the biggest difference being the upgrade to an 8Mhz MC68000. This system allowed you to run XENIX 3.x and address up to 1MB of RAM.

16B was factory maxed at 768k but I’m pretty sure 1MB is fine.

Yes, the 6000 can run all previous software.
