This is a weird post. Another one of those random things I never set out to write. But for some reason I feel the need to document things when there’s little solid information online. Seeing anything go down the memory hole depresses me, so the least I can do is keep something alive with what I find.
A Half-Second Rack Focus Shot
I was surfing some old TV commercials from the 70s and 80s, as one does.
The promo features a quick montage tour of all the hot new technology and crew behind the station you’re currently enjoying.
One of the machines that brings you their quality content has a fancy rack focus effect very early in the clip, at the 3 second mark. It’s on a keyboard with the label “Datacom 1200” across the top:
Once in a while I get mentally snagged by something like this.
I see a technology from the era I don’t recognize and go on a little detour for a half-hour reading about it. (Imagine this behavior spread out over a lifetime and a lot of things about me begin to make a lot of sense.)
Anyway, this time around I couldn’t find… well, anything. The entire search engine bandwidth for “Datacom 1200” in 2020 is devoted to a product from a Brazilian company named “Datacom” that sells a family of network hardware. And one of the lines features “1200” in the name.
Hey, it’s almost 40 years later. Whatchewgonnado?
Actually, it’s only partially true that I didn’t find anything. I fibbed a smidge.
In fact, the first search result for “Datacom 1200” is an empty listing on an printer ink company’s website. Among the various third-party ink replacements they provide, under their “Other” category, is the “Bell DataCom 1200“. 🤔
Ahh! Indeed, searching “Bell DataCom” as a full brand name sent me on a little trip that included this ad from Bell Canada in a mid-October 1974 issue of The Ottawa Journal; presumably* two older models of Datacom, the 500 and 600.
(I say ‘presumably’ because the Amiga 500 came out after the Amiga 1000; numerical superiority is not always an indicator of temporal positioning! 😉)
The Bell Datacom is a line of old school printer terminals from the Bell Canada’s “Computer Communications Group”.
Pretty much what I expected. No real surprise there.
“The Datacom 500 terminal is a compact, self-contained and quiet unit that allows office personnel to send and receive messages from a remote computer. It is ideally suited for consumer-finance applications and such transactions as journal entries, payment inquiries and file up-dating.”
“The Datacom 600 is a buffered keyboard teleprinter. This general purpose unit is useful in a wide variety of applications such as accounting information processing, order entry and invoicing, and inventory control.”
A Quick Zenith 33000 Detour
One interesting, apparently unrelated thing to note: “For more information, just dial Operator and ask for Zenith 33000.”
My first thought: maybe these Bell-branded terminals are actually sourced from a Zenith supplier and rebranded. Zenith, after all, dipped their toe into the computer world for a minute there, around that time.
But here’s the thing: do a search for “Zenith 33000”. You’ll find a lot of old newspapers returning results (from various sites that want you to subscribe to all of them to get access to a single article… good luck on that).
And it’s not limited to Bell, or even this line of terminals:
- “Increased sales… increased production… better inventory control… CCG helped Crossley Karastan Carpet Mills Ltd. achieve this, and more. Call us at Zenith 33000 today, if you too would like the red carpet treatment” — Canadian Datasystems (Apr 1981)
- “TRANS-CANADA TELEPHONE SYSTEM 10020 Edmonton Call Long Distance (No Toll Charge) & ask for..zenith 33000”
This, however, is a dead end.
A fun bit of telephony trivia, to be sure, but it’s completely unrelated to anything here. 😏
Back to the Datacom 1200…
A December 18th issue of Computerworld from 1978 refers to the 1200 model specifically, on it’s introduction:
“The Datacom 1200 family of teleprinters has been introduced by the Computer Communications Group (CCG). Available as a receive-only (RO) terminal or equipped with a keyboard, Datacom 1200 prints bidirectionally at a maximum speed of 180 char./sec and produces up to 132 char./line.
“Supplied by Digital Equipment Corp., the Datacom 1200 receive-only teleprinter can serve as a hard-copy output device for the Vucom 1, 3 and 4 series of CRTs, as a peripheral printer for mini- and microcomputer systems and for remote multicopy printing from a host data base in a stand-alone configuration.
“Rates for the Datacom 1200 in Canada are $2,715 for the RO model, with an additional $150 for the keyboard send-receive version. Filed rental rates, which are subject to regulatory approval, are $146/mo for the RO model, with an additional $7/mo for the KSR unit. Maintenance costs $44/mo.
And I’m gonna call it now: the Bell Datacom 1200 is probably a rebranded DecWriter III.
I can’t find anything specifically saying so, but I will make my case, and let you decide!
- The DecWriter III was released in January 1977. The Computerworld article is from December 1976, referring to January ’77 availability for the Datacom 1200.
- Both have 180 cps printing speeds.
- Both support 132-characters per line, max
- The DecWriter III was a 1200 baud terminal; likely where the “Datacom 1200” number comes from.
But here’s my smoking gun…
The keyboard of the DecWriter III compared to the corner of the Datacom 1200 we’re seeing in the promo spot:
- Same shape Shift and Return key (though these are probably common for the era).
- Return has a pipe/backslash and a delete key to the right of it.
- There’s a cluster of at least four keys above the -/+/~/backspace keys.
- There’s even a bit of space for the custom Datacom 1200 badge.
- Oh, and they’re basically the same color. 😏
I feel good about this. The evidence is pretty convincing. There’s just not any official word I’m finding. Yet.
If you find anything, or know first-hand, hit me on Twitter and I’ll update this post.
Still Remembered. Sort of.
One super interesting thing about “Bell Datacom” is that it shows up in a LOT of ink supplier listings — the 1200 model, specifically. In fact, ink listings take up most of the “Bell Datacom 1200” search results on Google.
Even Staples seems to have an atrophied entry for it in their ink category. Guessing there’s a lot of copy/pasting of “machines that use ink” among companies, and either the 1200 still gets play today (unlikely considering how little direct information there is on it), or it simply never got culled over the years.
This was a hell of thing to write based on a half second blip.
I just wanted this to be little more than an “I SEE YOU, DATACOM 1200” type post for anyone in the future who might look for it, and be confused by the lack of information. I didn’t expect to do a full on bit of research, and even come to a reasonable conclusion about it. Huh.
Until next time. 🍻
