You're right, and the point of using an 8/f is
that I walk into the room with it
on a little luggage cart and lift it onto the desk, plug it in and fire it up.
Indeed. If you had one to haul around, an -8/L with a desktop lid
would be heavier and larger than an -8/f (similar to an 8/e), but be a
reflection of the same sort of thing in 1968... a desktop computer for
under $10,000! (as was once advertised, IIRC)
?Of course, without a terminal of some sort as well as
mass storage (minimally a paper tape reader), it's
not much use.
Sure - I can't imagine that there were many PDP-8s that didn't at
least have an ASR-33. If you have access to one that's in the
tabletop (not pedestal mount) configuration, it might not be too hard
to wheel that plus your -8/f (or an -8/L) on that luggage cart - as
long as you don't tip the ASR-33 too far off of vertical, naturally.
A 4K machine plus ASR-33 (w/PTR) is enough to at least demonstrate
FOCAL. If it has core (all -8/L models did, but I don't recall if the
-8/f has the right PSU for core), you can even just turn it on and
have it start chattering - instant resume from hibernate!

Sure, 10 years earlier, but there was something like that two years
earlier, and perhaps 5-6 years earlier (the PDP-8/S, though I'm not
sure what you could reasonable show off with a 4K tabletop unit since
the TTY interface is external).
Fiddly details aside, it's still cool to wheel in a "personal
computer" from the era and watch the audience gape - I've done that
with my -8/L.
