Need help with AT90CAN128 coding
Not that I've used that chip, but isn't there a setting that gives you the choice to try to resend the message if an ack is not received ? or just try once...

How to compare..
Well by asking that pins you should connect to I'd guess you haven't read the datasheet ? As you can see the mega128 has an ADC, you could just simply connect the voltages to...

3 wire SPI connection
Why in god connect MOSI and MISO together through a resistor ? Connect MOSI -> DI, MISO -> DO, SCK -> SCK, optional IO -> CS works every time!

ATMEGA as RTC?
I've used DS1305 alot, and it's a good chip. Never used DS1307 but I'd guess it's very simular. The DS1305/7 is antique before the battery runs out :)

3x mega88 communicating with UART?
if you connect more than two devices to rs232 you need aditional error handling since RS232 is point-to-point, not network as RS485. If you hadd 3 devices to the same bus, you...

Help: What am I doing wrong?
You should also consider getting used to sinking leds instead of sourcing them in the future for bigger projects where the current usage gets higher.

And it was gone in a flash
Check your connector on the end of the flat cabel comming from the JTAG, I've had great problems with it.. causing the same event error. Also check the USB connector in your jtag...
