My idea is this: build an ethernet board for the

board, only faster. 2. it has enough brains to analyze outgoing frames to

de-encapsulate it and transmit it as straight IP. - this is a software issue,
really, but it needs to happen in the firmware of the ethernet board, so...

It seems to me that it would be a lot easier to write a driver for an
existing parallel port ethernet adapter. I looked into this some time
back and decided I'm just not a good enough programmer ;). But, if
you're really into this it would eliminate any hardware development.
There are other possible devices that could be modified too - like
the Asante SCSI -> ethernet adapter. I picked up one of these to
see if it would be any easier to work with but was never able to find
sufficient documentation to answer my questions. For now, I appletalk
to my mac and ethernet to my other machines. It gets the job done but
just doesn't satisfy the dogged computer geek in you.
While I'm here - does anybody want a Tandy OEM'd dual bernoulli box?
I just dug it out of the back of my storage space and can't remember
just why I have it.
