Uthernet II update

Sorry folks … been a long time coming but an update is finally here.

About a year ago I was sending out first alpha, then beta versions of the new Uthernet II card. As I had done most of my testing in a IIgs Rom1 and an enhanced IIe, I was dismayed to find out that the card was not working properly in a unenhanced IIe or in most IIgs ROM3’s.There were two issues 1) the timing was off and there were intermittent problems and the interrupt line caused issues in the IIgs with the control panel activation sequence.

With Kilian Leonhardt and Daniel Krue’s suggestions I was able to update the circuit so that both of these problems are no longer an issue based on the testing both Kilian and I have done. So I made modifications to the PCB and just today received some new boards. Later this week I will be cooking up a few and then will proceed with the final testing.



After that if all goes well, I plan to send out a small survey with a few questions and then we can proceed with taking pre-orders.

    This is great news. Please add me to the list for the survey or anything else you’d like about this. I’d love to have one reserved for me too. I have an enhanced IIe I’ve been want to try and bring into this century somehow.
