Working on Uthernet II

Hi All … has been a long time now between posts or updates but in the back ground Oliver Schmidt and I have been working on a second generation Uthernet card. This card will not be backward compatible with the current Uthernet from a software standpoint but will perform the same function. The plan is to use the Wiznet W5100 chip in indirect access mode. Oliver has already coded a Contiki driver, IP65 already contains support for the W5100 chip courtesy of Jonno Downes, both David Schmidt and Ewen Wannop have indicated they would be willing to update ADTPro and Marinetti respectively to support this new card.

After 10 years it seems like I have come back full circle to the Wiznet chip as my very first Ethernet card was based on a w5100 predecessor.

The ball is rolling to produce some alpha/beta boards which I hope will be ready in a months time. A few of these cards will be available to folks who aren’t shy about testing new hardware.

    Fantastic! I’ve been checking back now and then to see if the site had been updated. Very glad to see signs of life. I’d be more than willing to try one of these out as soon as it is available.

    Wow, awesome news! : – )

    Good news!
    I hope the card will offer the ability to be identified from its I/O space, using the standard Apple method.
    That would ease identification and driver writing.

    Thank you,

    I want to see this fantastic machine and how to use it with apple II.

    I read a comment elsewhere expressing concern over the lack of software backward compatibility. I want to share my response, just in case other folks have the same comment:

    “IMHO, the lack of software compatibility is a good thing in this case. The old Uthernet required the programmer and the slow Apple II CPU to do quite a bit of work. The new Wiznet W5100 based Uthernet includes a complete TCP/IP implementation on the card, thus relieving the programmer and CPU from this significant task. I expect Uthernet II software to be easier to write and faster to run compared to Uthernet ‘I’ software.”

    Cool beyond cool. I have a LANceGS as well as a 1st gen Uthernet
    both work well but this looks interesting. when you are ready for commercial run, keep me in mind. I will buy one
