Ah yes, you're correct. The Z80 ran the program and the 6502 then handled I/O. https://en.wikipedia.org/wiki/Tube_%28BBC_Micro%29?wprov=sfla1 On Fri, 21 Oct 2016, 18:40 , <Valdis.Kletnieks@vt.edu> wrote:

The BBC Micro which was 6502 based had an add on that let you connect a Z80 straight onto the same bus.
