As far I can tell, yes, pretty much. That fits, because it was
written for the 20th birthday bash.

There may be some historical errors. For example, I don't know if
RSTS has any relationship to IOX. I rather doubt it (but I've never
seen the IOX sources, and I only barely glanced at the docs around 30
years ago...) The cultural heritage is TSS-8, from what I've heard,
though I can't confirm that from personal knowledge either.

The change from .CIL to .SIL happened with RSTS V5B...

TECO did appear -- as a real RTS, not as two Basic programs -- in
V5A...

Some of the fantasy items have a connection to reality:
- There wasn't a Unix RTS, but Bob Fraser ported csh to RSTS.
- Basic for RT11 supported line numbers up to 65532.
- Directory and data cache can be displayed with SDA.
