David,

I'm not understanding why you need extra hardware, the mac doesn't use it?
I started AT on my macs using just the extra printer cable I have
joining the serial ports of 2 machines. (works great)
As for processor not being enough.... on a //C it's not doing anything else 
anyway and as for memory .... where do you put stuff you load from a disk
drive? The //c serial buffering as implemented should be sufficient.

I realise it is moog point anyhow .... it aint there. But someone could
architect  a minimal implementation just so you could do loads/runs.
I saw a book which describes the protocols and may investigate 
what it takes to start a connection.  Can't be that bad.
