Have you tried going through the various checkout procedures in the manual to make sure they all still work? If the 5370 firmware authors *didn't* bake some timing dependencies into that 6800 code, they were the exception. Of course, if your emulator is cycle-for-cycle faithful to the 6800

Hi, I got my hands on a Z3815A(with hockey puck) and trying to communicate with it. It seems that Z38XX and gpscon work ok at first, then looses connection in about 30min.(error receiver timeout) If I reestablish connection, it works fine, but in another half an hour, it looses connection again.

Perhaps an AT91SAM7SE512 - it has an external addr/data bus, with quite flexible configuration, and USB - but no Ethernet :) Regards, Javier One thing I like about the SAM7X512 (and others) is that in exchange for giving up the external bus interface you get USB -and- Ethernet. The m6800

That is true, the SAM7X... are very nice. I currently use them a lot (mainly for its CAN bus). The bad thing is that they have Ethernet but no phy, so an external phy must be used. In that respect, for an application using Ethernet I would use a Luminary, that has both MAC PHY on-chip and
