There is no place where you could connect the additional two address lines that a 4-way clock port expander needs.
Further, there is no driver for RR-Net on the Amiga, and I would not encourage anyone to write one, as it'll be dead slow and totally not Amiga-worthy without IRQs. The Amiga deserves better. I'm thinking of an adapter that lets you connect the X-Surf-500 between the Chameleon and the Docking station, but need to investigate if we have a sufficient amount of signal lines available.
Yep. I think I asked about whether it would work on the amiga or not and that it would need a driver but it'd suck the life out of the cpu as it did not support interrupts (if I remember correctly) But -- I was mostly just asking electronically in my question above, whether or not the rrnet would still work with the c64core if it was connected via a clockport-extender. But you kind of answered that by informing me that the clockport lacked the extra addresslines.
Is the clockport on the tc64 not quite alike the clockport on the a1200 pinout-wise ?
