This image of people wearing swimsuits in a room with computer hardware popped up on Twitter recently.

a woman wearing a swimsuit operating a computer in front, a man and a woman wearing swimsuits reading in the background

Where was this advertisement published, and what computing product or service is it offering?

    Not sure how the advert is 'sexist'when it features men and women!

    Especially when the man is showing more skin than any of the women.

    @arBemo58, look at the footwear. The man is wearing comfortable slippers, while the woman is wearing "check out my legs" spike heels.

It's advertising computer room air conditioning.

enter image description here

No doubt appeared in some late 1970's or early 1980's US-based computer magazine. But exactly which one I couldn't find based on a little bit of searching for phrases and keywords in the full advertisement.

JdeBP reports the ad appearing in 1982 and 1983 in "Computer Decisions" magazine. I could not find an on-line copy to confirm that but I did dig up a Google Books search that refers to the ad.

"Airflow" in Computer Decisions Volume 15

    Telex and TWX but no Fax # is a clue to the timing - i.e., definitely no later than early 1980s. Jun 23, 2020 at 17:24

    Official Gazette of the United States Patent and Trademark Office, Vol. 1033, Number 5 ("Trademarks"; August 30, 1983), page "TM 642", says of the "DATAC" mark: "For Computer Room Air Conditioners (U.S. Cl. 34). <newline> First use Jul. 16, 1982; in commerce Jul. 16, 1982". So, that puts a lower bound on the date. That, combined with manassehkatz-Moving 2 Codidact's comment, leaves a pretty narrow time-range. :-)

    The publication is most likely a "trade rag" as indicated by the "Circle 102" at the bottom. At first I thought it might be from Datamation, but that seems to have used "Circle [num] on Reader Card" in the relevant time frame.

    @manassehkatz-Moving2Codidact You know what you have to do. Drive out there and find that old guy that's been with the company forever, show him (yes, it will be a him) the ad and he'll hopefully dig out the actual magazine.

    Apparently they were. Further searching turns up volume 15 of Computer Decisions, Hayden Publishing, 1983; pages 77 and 163. Page 163 has "circle 92", though. For "circle 102" you want the same advertisement in volume 14 of Computer Decisions, also Hayden Publishing, 1982, page 179.

I see DATAC on the advert. On googling I found the following:

Since 1977, the DTAC commitment to the customer, a quality heavy equipment air conditioning product and specialized service has helped us grow into a reputable manufacturer of heat/cool systems for heavy equipment. http://www.dtac.com/

This tells you an earliest date for the advert. Furthermore they are a US firm so the computer is probably an IBM.

Here's an IBM 360. You can see that the console is a teletype so this is an earlier model than the one in your picture which has monitors.

I'm sure a little googling would track down the actual model. I don't have time to do it right now.

    I love the old tape drives and classic style. Makes me want to land a man on the moon by the end of the decade! Jun 24, 2020 at 17:24

    I don't think we can see the actual computer in the photo. We can see a couple of vacuum-column tape drives in the background, which are definitely IBM style; they could be 3420s. The terminals in the foreground could easily be IBM 3270s.

  • For some reason that equipment in the original ad screamed "DEC" to me. Perhaps the shade of blue.

  • @Chromatix The terminals are a pair of 3278s. Jun 25, 2020 at 13:56
  • @Eight-BitGuru I had the right series, then. I think the case shape is about the same, but the keyboard is different.
