We are trying to install one of these on a 3b1, but we are having problems getting some of the cards to work. We have the following configuration: In the internal slots: Slot 1: 2 meg RAM board Slot 2: EIA/RAM Combo Board Slot 3: Expansion Unit Card In the Expansion Unit: Slot 5: Tape Controller Slot 6: EIA/RAM Combo Board Slot 7: EIA/RAM Combo Board (right hand slot, looking at back of unit) None of the EIA/RAM cards have memory installed. The serial ports in the EIA/RAM cards in the Expansion Unit are not recognized by the system software. This must have something to do with how the system identifies the cards to tell what hardware is installed. The manual for the expansion does say that any ram cards must be installed in the internal slots, but we thought that we would be all right since there is no ram installed on these boards. Is it possible to get these cards to work in the expansion unit? By the way, the tape drive controller card works fine. Jeff Wieland wieland@ecn.purdue.edu

I'm very unsure why this happens, even with the memory removed from the cards. I replaced both of those cards with others we had in the office with no places for RAM (ie. no sockets at all). The Dual EIA cards then were recognized by the expansion unit. >Is it possible to get these cards to work in the expansion unit? >By the way, the tape drive controller card works fine. ... The fact that your tape controller is working is good. That means the signals are getting to the expansion unit fine. I don't know what the official word from AT&T is, and why they wouldn't work in the expansion unit. -Lenny
