[Techtoolslist] 9100 easter eggs & hidden

[Ian Eure]

I’ve found a couple 9100-related easter eggs and undocumented
features.  I was going to write this up and post here, but it got
really long, so I made a blog post instead.

The most interesting thing I found is an undocumented TL/1 
function
which lets you call out to an OS-9 binary.  This is super cool and
potentially extremely useful.
