You mean that they are using a tried and proven architecture that helped the 4.77 MHz IBM PC find success in 1982? Yawn.... The IBM PC keyboard had its own Z-80 CPU way back then and likely every single PC of any sort since then has done this. And then there are the disk controller CPUs. Wasn't that introduced around 1984?

Do you have any further information on this? Having opened up an IBM PC keyboard, and knowing that Z80 CPUs were still fairly expensive in 1982, I'm a little surprised.
