Ah, thanks. Now that you mention it, high impedance data lines ("open bus") do play a role in other platforms as well. Even more so, on the C64 for example some undocumented instructions cause conflicting drivers to drive the same lines and produce randomish/unstable outcomes. And nice to know that there are indeed metastability issues that crop up very visibly in the PlayStation! |
