Trs80 Coco series used the 6809 CPU that is 16 bits. The article talks about Linux on 8 bit systems.

I'd say the Mega65 might be a good 8 bit machine to port Linux to. http://mega65.com

The 6809 was 8 bits, in the same way Z80 and 6502 and 6800 were: 8 bit data bus, 16 bit address bus.

It had a few 16 bit instructions: arithmetic on data in registers, or loading/storing a 16 bit register (8 bits at a time). I think the Z80 did as well.

Here's Wikipedia: https://en.wikipedia.org/wiki/Motorola_6809

It also had an 8x8 mul with 16 bit result.

One 16-bit feature doesn't make a CPU where every other feature is 8-bit a 16-bit CPU.

I don't think I claimed it was a 16 bit CPU.
