(...) This does point to a concern that I have. I'm wondering if the Bluetooth interface replaces the IR comm link that the RCX used to send messages back and forth between other RCX bricks. I don't know Bluetooth so I don't know if it is (...) (20 years ago, 15-Jan-06, to lugnet.robotics)

(...) Yes, I suspect the same. The ROM mask *is* the custom part of the chip that LEGO can easily define without big expenditures. I noticed that the atmel chip also has a boot ROM that is separate from the flash. If they use that chip we might (...) (20 years ago, 15-Jan-06, to lugnet.robotics)

Hi Chris, (...) I'd guess at the AT91SAM7S256, the ST type has a lot of stuff that isn't needed (CAN, smartcard interface, HDLC interface) and 16K extra flash which aren't mentioned in the LEGO press release. See (URL) and (URL) Also take a look at (...) (20 years ago, 15-Jan-06, to lugnet.robotics)
