[rescue] New to me PDP-11/23+

[John Hudak]

In one of the processor handbooks, I think it is called the microcomputer
handbook, there is a chapter that tells you everything you need to know
about using ODT. Have you read that? It is on bitsavers.
Sorry I can’t be of more help, been at least 20+ years since I used ODT.
Also I think DEC micronotes had some description of ODT features.
I’ll slog through my library and see if I can find anything helpful
