I was recently given a Heathkit H89 with all three distribution disks. The system boots CP/M 2.2, looks for a configuration file, doesn't find it on the write-protected boot disk, and initiates a setup program. The setup utility offers a "standard" configuration, or I can display settings for all of the physical and logical devices, and change those settings. Upon exiting the setup program, the result is always the same: all keyboard input produces double characters on the screen. I don't see anything in the setup utility pertaining to local echo. What am I missing here? Glen Goodwin 0/0
