Re: [Ql-Users] Ethernet chit chat...

   I keep my point - wizchip offloads the work of the (already underrated) 
QL processor. Having the (entire) TCP stack into a coprocessor only makes 
things fast. And working as a memory device, it can be mapped into QL memory 
space and very little hardware be incluided on the board.


   I'd like to help in development.

Subject: [Ql-Users] Ethernet chit chat...



I have been presented with two good contenders for an ethernet solution for
the QL. There might be others; I am open to suggestions and may add more 
to

the list.

I would like there to be a *polite, friendly, respectful,
constructive*debate about the relative merits of the two devices. Once
you have
expressed a view, that's enough. No need to restate it, unless you add
something further. It is very important that discourse be *focused
entirely*on solving the problem of getting ethernet onto the QL.

Please read the data sheets and form an opinion about which would perform
better on a QL at 7.5MHz or a SGC system at 25 MHz. There is already a TCP
stack in existence; whether you wish to use it or not is a matter for 
you -

one of the chips is a microcontroller that has its own stack.

Here are the contenders:

Wiznet WS5300
http://www.wiznet.co.kr/UpLoad_Files/Re ... _V128E.pdf

versus
Cirrus Logic CS8900
http://www.cirrus.com/en/pubs/proDatash ... 00A_F5.pdf

If there is a clear consensus, I will assemble some functional prototype
boards using the favored device, then send boards and documentation out to
a limited number of people who express an interest in doing development
work with them.

There would be some gentle conditions:

1. You'd join a developer mailing list and report occasionally on progress
you'd made to the other three people and me. Others could join the list to
provide feedback, etc. The list would allow you to self-co-ordinate your
efforts within the group. I would not be the boss of you. I would not own
your work. There is no schedule or deadline.
2. Anything you do, once reaching a state of development greater than
"alpha", would be open source and freely distributable. A GIT repository 
or

similar would be nice.
3. I would, upon release, host information and downloads at SinclairQL.com
so people can explore the code or develop it further.

If anyone develops anything to a point that it becomes possible to add
ethernet to a future board, or standalone, I would work out a way to
produce them for the community. If not, you can keep the card as a
curio/plaything/collectible, or send it to someone else who has shown an
interest.

So, let's begin, shall we?
