In the midst of my documentation research, I've done a little analysis on the life
and times of this whimsical little phrase which first appeared in the "HOW TO GET
STARTED" or basinf section of the Third Edition manual (a derivative of the original
login(VII) page):
"When you type to UNIX, a gnome deep in the system is gathering your characters
and saving them in a secret place."
Aside from the wonderful imagery of the terminal interrupt driver as a little gnome,
I've found that this line has some implications regarding UNIX documentation
lineages. This exact verbiage survives in the research line through the Sixth Edition,
and is slightly edited prior to the Seventh:
"When you type characters, a gnome deep in the system gathers your characters and
saves them in a secret place."
The latter of the two changes holds with a trend over time of using progressive rather
than continuous language. That aside, simple change of "to UNIX" to
"characters". Seems simple enough, reduce redundancy and make it more clear
what is happening. In this same breath, basinf was merged into intro. Checking the Tenth
Edition manpage sources on the source tree, this version then seems to persist for the
rest of the research lifetime. Peering across into BSD-land, I had to pull a paper copy
for this one because I can't find the intro document in the tree, but it likewise has
the same exact text, so this version also persisted through the remainder of the UCB
development period.
When you start to look into other Bell lineages, things get a little more interesting.
Let's start with MERT Release 0. This manual was produced in October, 1977, and has
a "gnome" message identical to that in the Sixth Edition manual, so presumably
by this time, the old text could very well have still been up in research. Unfortunately
we only have scans of this manual, so I can't say whether the merge from intro and
basinf to just intro has happened yet. Additionally, this may not reflect the case with
USG Program Generic 3 (or any of those) as the intro is one of the sections marked as
modified from the USG manual.
Next let's check the situation with PWB 1.0. To start, the intro and basinf
documents have been merged into a document titled "introduction", which may very
well indicate that this manual page at least was produced after the merge in the research
line, and given this was July 1977, that's a case for the MERT 0 page likewise
probably being a merged page. However, the text reads:
"When you type to UNIX, a gnome deep in the system is gathering your characters
and saving them."
So a different modification of the Sixth Edition text, we still have "to UNIX"
and the continuous "is gathering...and saving". What does change is we no
longer know where the gnome is saving those characters. We've now lost the secret
place, research and BSD carry on knowing the real story, and MERT 0 kept this intact as
well. Taking a look further afield, in the System III manuals, originally produced in
1980, we see the same as PWB, a merged intro document (now just named intro again), and
the same text, the Sixth Edition text minus the secret place commentary. So whatever
merges of documentation took place between PWB 1.0 and 3.0, it seems the updated text from
the Seventh Edition was never picked up, and the modified line persisted through to this
point. Checking forward, this text persists into the release of PWB 5.0. The first
release of System V only changes "UNIX" to "the UNIX System",
consistent with nomenclature changes throughout documentation in the PWB 5.0->System V
transition.
Taking a little peek aside into yet another lineage, the CB-UNIX 2.3 manuals circa 1981
likewise carry this same text, with the "secret place" removed. Unfortunately
we don't have any other versions of CB-UNIX manuals to compare with, but the specific
page in question actually lists CB-UNIX 2.1 in the footer with a date of November 1979, so
the PWB-ish text in that lineage dates to at least that point.
There are a few different variations circa SVR2, with the 1983 BTL version and 1984 DEC
processors versions of the manual changing the first bit to "When you type to UNIX
system", whereas the 1986 HRW tradebook manuals state "When you type to the UNIX
system." So the "the" is dropped, "system" is lower-cased, but
then the "the" is added back between 1984 and 1986.
Finally, there is one more variation on this line, the saddest one of all, that appears
circa System V Release 3 material in 1987:
"When you type to the UNIX system, your individual characters are being gathered
and temporarily saved."
"Pay no attention to the gnome behind the curtain," says AT&T, removing all
whimsy from the equation. This persists into SVR4. Can't say what happens in
SVR4.2, I don't have one of those user's manuals, but in any case, it's
probably save to assume Novell didn't resurrect the gnome. So just to review the
strange and wonderful journey our little gnome has been on:
- Introduced in Third Edition
- intro and basinf documents merged between Sixth and Seventh Edition
- MERT 0 takes the old text
- PWB line takes the old text and drops the reference to a "secret place"
- Seventh Edition adjusts the text to drop UNIX redundancy and use progressive
language
- PWB line keeps rolling with their modified text, CB-UNIX takes it up (or vice versa?
can't conclude anything there)
- PWB to System V process converts most references of "UNIX" to "the
UNIX System"
- Along the way, the "System" is ultimately lowercased, the "the"
gets lost for a while and comes back
- AT&T finally removes the gnome reference in SVR3/1987
- Research and BSD keep the Seventh Edition text to the end
Granted, this is a very trivial detail, but one that does demonstrate some flow of
documentation revisions and what sorts of changes different groups were making to their
documents, what with research making changes to the grammatical style while the
PWB-then-commercial line grew more sterile in this presentation over time. This then
shows at least one instance of a lack of merging of aspects of the Seventh Edition
documentation back into the PWB line after the split of 1.0. Eventually I hope to
illuminate many more such areas through the diffing and historical analysis I'm
performing.
By the way, I believe a few list members had indicated at some point or another being in
possession of some USG Program Generic manuals. If you happen to catch this, and have the
time, I'd be ever so curious which of the above, if any, variations on the text they
contain. This particular line is immediately following the "How to communicate
through your terminal" heading the "HOW TO GET STARTED" section.
Anywho, I hope this was an entertaining diversion. While most of the analysis I'm
performing concerns software details and version differences, it's also nice to take
a closer look at some of the other sorts of changes that have happened in the lifetime of
the system's growth and diversification.
