We have several ICM3216's which we are pretty happy with. We are trying to connect 2 (for now) of them through the Minibus. We have them physically connected, have changed the jumpers for the Minibus ID numbers and the interrupt addresses, but we are having problems. They do not seem to communicate reliably over the bus; i.e. if we have values 1 2 3 4 5 6 7 in memory addresses 0,1,2,3,4,5,6 on board 1 and we try to read at address C00000,C00001,etc. on the other board, we get 1 2 0 23 17 etc. In other words, occasionally it works fine, but we can't find any rhyme nor reason to when or why. Has anybody else done this? Anybody from National out there who can help? The setup is 2 processor boards one with 1MB, one with 4MB connected through the correct 96 pin connector (minibus connector only), jumpered as minibus masters 7 and 6. We've tested continuity through the 2 boards+connector & it's fine. Help! Please! Thanks ../Dave
