[ Retro Scan of the Week ] Computer/Phone/Terminal

Rolm Cedar Telephone Terminal Computer in BYTE - 1985All telephones should look like this. (click above for full scan)

It’s the Rolm Cedar — a combination PC/Telephone with 512K memory, a 9″ monitor, dual 5.25″ floppy drives, and MS-DOS 2.11. I’m not sure if this unit ever went into production, but I want one! (It also came with a keyboard, not pictured.)

    I had the same reaction when I saw the picture, “Holy crap! I want one.” How cool would it be to gut it and turn it into a modern PC?

  2. Daniel B. Says:

    This looks similar to a Nortel ‘Displayphone’ from the early 80s.


  3. Moondog Says:

    If a Cisco IP phone had a grandparent, that’s what it would look like.

    Either that, or a fax and a pc made a baby.

  4. John Muir Says:

    DOS could really have used a tech support hotline built into the base unit.

    Ooh, that would have to my late grandfather’s LC.

    It wasn’t an inherently weird (i.e. unique) computer, but what happened was my grandfather was in a MUG and literally collected software of all types. With at least a full row of shareware/freeware extensions (maybe two), it’s a miracle that the thing didn’t spontaneously burst into flames.

    Yes this did go into production (and at the time it was cutting edge) and it did play games also however when IBM purchased Rolm they killed this and the Cypress (without floppy drive)product . They didnt want to compete with the IBM PC that was just released. Also at that time the company released a phone called the ETS really space age look it was the first digital phone they offered. 3 lines on 1 pair of cable. Yes what a company that was!!

  7. Eric Forslin Says:

    Oh my goodness! That is the sexiest piece of tech I have seen in my life! And it runs DOS 2.11?

    I have to get one of these relics and put it on my writing desk! It really turns me on!

  8. Eric Forslin Says:

    In fact! I think I should replace my Motorola Droid X2 with one of these!

  9. Doctor Rolm Says:

    The Cedar was a unicorn. I never saw one. The Cypress, however, was very popular……..and a big POS. That display was an MF to repair. The rest of the phone worked OK. It had a little keyboard the slid out from under the keypad. The whole thing was really just a big dumb terminal with a phone and dialing directory. It used RS232 for the data link and required an RPD circuit card in the CBX and a Cypress load module wired into the MDF. Thank goodness I don’t have to support those anymore. We used to have some laying around for parts, but I think they are all history now.

  10. Was There Says:

    I was the lead of the design team that built both Cedar and Cypress. Only about 1000 of these were sold. It was a fully self contained PC that locally ran MS-DOS 3 (if memory serves). It is funny to see it now as an interesting antique. I might still have one in my basement. 🙂

  11. Benj Edwards Says:

    Was There,

    Great to hear from you. If you do happen to have one in your basement, is that something you’d be willing to part with? If so, I’d love to add it to my historical collection. I’d gladly pay shipping.

    Just send me an email.

    I was a ROLM tech in early 80’s and i had a Cyprus and Cedar in my office. Got rid of id in late 90’s. I do regret it now. I went thru all the ROLM technologies from CBX 7000 8000, and then 97xx when IBM bought us.
