I am working on a DX120, probably the last one sold before Comdial folded. I need the PC-DBA software but cannot find a source for it. They want to make a lot of changes but I want to back everything up first. I did some changes on a DET but I'd prefer a backup before going on. Also, they have the inskin VM. I need to get into it and reset passwords and mailboxes. Or maybe re-init it. Does it work like the Tadiran and just uses a 9-25 cable?
