Clock Port 101?
Leif Bloomquist
The Retro Replay cartridge has one.
The MMC64 has one.
The upcoming IDE64 v4 will have one.
They allow you to connect the RR-Net, SilverSurfer, and so on the the C64.
But what do the clock ports do exactly? All I've found through Google is
that Amigas also have one, and these add-ons were originally intended for
the Amiga.
What would be involved in creating a C64 "cartridge" that contained nothing
but a clock port?

that should be relativly trivial, its just a bunch of i/o lines... a simple
adressdecoder and maybe some gluelogic is probably all you need.

Unix *is* user-friendly; it's just picky about its friends.

Can you be more specific? ;-) What addresses would it appear on? What's
the purpose of each of the pins?

that doesnt really matter. eg an amiga could have several clockports at
different adresses...could be the same for c64. the RR maps it to $de08

never looked at it in detail :) but i'm sure you can find that out easily by
looking at the RR docs and maybe some generic amiga clockport docs. i would
think that there is a CS line, a RW line, and a few address- and
datalines - ie nothing extraordinary.
