Jump to Uthernet I FAQ
Looking for the Uthernet II manual (updated January 28th 2016) --> Get
it here
Q: Why did you change from CS8900A to W5100?
A: The W5100 has a number of factors in it's favour. It is physically smaller
and costs less to procure. It also has a hardwired tcp/ip stack which can be used to offload the cpu and give some extended functionality not possible with the CS8900A.
Q: Will all my favorite software for the Uthernet I have to be updated?
A: Short answer is Yes. Contiki, IP65, Marinetti and ADTPro have all been updated. You will need to download new versions once you have your card.
Q: What does it cost?
A: Pre-order a card @$69 USDper unit. Please check our product and order web pages for up to date information concerning pricing.
Q: What types of Apple II systems will it work in
A: The production card should be hardware compatible with Apple II+, Unenhanced IIe, Enhanced IIe, Apple IIgs Rom1 and Rom3. The Apple III is yet to be tested. Software support depends on the model of Apple II.
Q: What slots does it work in?
A: Tested in all regular slots. Because the Uthernet II card has no onboard ROM it should not conflict with builtin hardware in the IIgs.
Please note that Uthernet II is a full width card. Please be carefull when installing the card in a full system. May conflict in slot 7 with long memory cards.
WARNING: The Uthernet II card installs into your system with the Ethernet Jack
facing towards the keyboard, not the back of the computer.
Q: What software does it use?
A: Uthernet II has a built-in TCP/IP stack but still requires software support
to do useful things. Contiki, IP65 and ADTPro have been updated by Oliver
Schmidt to provide a compatible driver and Ewen Wannop has developed a
new driver for Marinetti stack for GS/OS. A driver is required in order
for the system to talk to the card. If you are a software developer we
can help you understand how you may get your application working with this
card.
Q: Where can I download the software
A: Please check out our downloads page for links or files to Uthernet II compatibile
software http://www.a2retrosystems.com/downloads.htm
Q: Is the uthernet II emulated in Applewin emulator like the Uthernet I?
A: We are not aware of any emualators that have support for the W5100 chip and would thus allow an emulated Uthernet II card to function.

Rates noted here were avg throughput of a Contiki disk image (140K) transfered by http protocol from a PC running http_fs to the Apple IIgs memory.
Q: What types of Apple II systems will it work in
A: So far the Uther card has been tested in an II+, II+ Clone, unenhanced
IIe, enhanced IIe, platinum IIe, Laser 128, ROM01 and ROM 03 IIgs. The
card currently will only work in a real Apple II+ if it has a 6502A (2Mhz)
or better.
Q: What slots does it work in?
A: Tested in all slots. Because the Uther card has no onboard ROM it should
not conflict with builtin hardware in the IIgs. Please note that Uther
is a full width card. Please be carefull when installing the card in a
full system. May conflict in slot 7 with long memory cards. Also note on
a II+ some slots may not be suitable due to cabling restrictions (slots
2 or 4 seem to be preferalble from that perspective)
Q: What software does it use?
A: Uther requires a TCP/IP stack to do useful things. Contiki contains a TCP/IP
stack and so does Marinetti for GS/OS. A driver is required in order for
the card to talk to the TCP/IP stack. A compatible driver is included with
Contiki and a compatible driver for a beta driver for Marinetti has been
completed. If you are a software developer we can help you understand how
you may get your application working with this card. If you are an apple
II enthusiast then see our links pages for pointers to apps that will work
with this card.
Q: Where can I download Contiki
A: The offical site for Contiki is http://www.sics.se/~adam/contiki/. If you are looking for a disk image to run contiki with your Uther Card you can download that here http://www.a2retrosystems.com/downloads.htm
