[avr-gcc-list] Memory timing differences between the 103 and 128

Hi,

Earlier, someone sent a message about timing differences in the memory interface between the ATmega103 and ATmega128.  I ignored it because I didn't think it affected us.  We have a VFD that works in 103 compatibilty mode but not in 128 mode.  I think it's a timing problems and I tracked down all the connections.  It turns out that our VFD is connected to the external memory interface on the ATmega128.

Has anyone figured out what the time problem was and/or a way to solve it?
