The binary files exist but I'm not sure they're in the right format. The .DMP file is a WAITS operating system memory dump, so it needs either: 1. A WAITS system to load it (there are hobbyist WAITS systems) 2. Conversion to a standalone format that SIMH can load directly What emulator is your friend using? Common options: - SIMH (ka10, ki10, kl10, ks10) - KLH10 - SIMS (WAITS-specific) - A hosted WAITS system online Also - does your friend have an OS running, or are they trying to load this as a standalone binary? If they have a working WAITS system, they should be able to just transfer the original fdisk.txt or fisk_clean.oct and load it. If they need a different format, let me know which emulator/OS and I can create the right binary.
