You could even expand the userport in a similar way, using a 74165
serial-to-parallel converter :)
If the cluster bus is using a serial approach, a 74165 (serial-to-parallel)
converter could even be used to include PETs in the network, replacing
the broken VIA SR input :)
There has been going on a discussion for a 6502-based serial bus protocol
on http://www.6502.org .Although I haven't really followed it to the end
in all details, I think it might be interesting to at least read it.
