I'm new to the forum and just pulled my IIe out after being in storage for a long time. I'm using ADTPro 2.1.0 to create some disks, but am having some trouble getting the serial working. When I enter IN#2 and press RETURN, I don't see the APPLE SSC: prompt. What I get is a bracket and then a random character after that.
I verified that the card is in the second slot from the left as you look at the machine from the front, the dip switches are set to SW1: 1001111 SW2: 1101100, and the jumper block has the arrow pointing up since I'm using a null modem cable.
It's entirely possible the machine needs some TLC, but I don't know where to start with that. Any help would be greatly appreciated.
