BetoB Posted August 25, 2021 Share Posted August 25, 2021 Greetings, community! I have a full CoCo 3 system, including the Tandy DMP-107 dot-matrix printer. Some time ago, the printhead was damaged and the printer is useless, even though the auto test works fine moving the printhead and trying to print, but nothing. Does anyone knows where to find a replacement for the printhead? Original or compatible, I'm not picky I tried several websites and they have other models, but not the DMP-107, it was a little basic dot-matrix printer, perfect for the CoCo. I really want to have my whole system back online. The CoCo, the floppy drive, even the mouse and the joysticks work fine, and I have some software, original and from The Rainbow magazine, that requires printer. I will appreciate some help! Thanks! Alberto. Quote Link to comment Share on other sites More sharing options...
Turbo-Torch Posted August 25, 2021 Share Posted August 25, 2021 Do you have a photo of this printer? What year was it made? I know of the 100, 105, 110, 120, etc. and the line printer designations before those. I've never heard of a 107 and can't find it in any of the catalogs I searched through. No Google image hits either. I have a nearly new 100 that I believe lost it's ROM after a nearby lightening strike. Head should still be fine and it printed great before the strike. If by chance the 107 uses the same head, I can pull it and send it your way. Quote Link to comment Share on other sites More sharing options...

Alberto. Alberto, You might be better off getting a DMP-130 or DMP-130A from an eBay seller. This model was very common and dependable. Print ribbons are still available. The DMP-107 showed up towards the end of the TRS-80/Tandy era. Michael Quote Link to comment Share on other sites More sharing options...
Turbo-Torch Posted August 26, 2021 Share Posted August 26, 2021 Thanks for sharing that. I was searching around when the 105 and 110 were released. Odd that Tandy went that far back in the numbering so late in the game. Unfortunately my 100 (same as Line Printer VII) predates the 107 by about 10 years. 1 Quote Link to comment Share on other sites More sharing options...
Michael Kline Posted August 26, 2021 Share Posted August 26, 2021 My pleasure Yeah, I remember the DMP-100. I also had one in the 80s. I remember it being slow, loud and uni-directional. LOL The other thing that I can think of; is for Alberto to add a search for the DMP-107 on eBay, so that it will notify him when another one comes along for sale.

Just a question: Does the DMP-130 has the DIN port? That's my main concern and that's why I was trying to recover the 107. Quote Link to comment Share on other sites More sharing options...

I will try to have a picture of the printhead to give you an idea. Quote Link to comment Share on other sites More sharing options...

That's my main concern and that's why I was trying to recover the 107. Absolutely. It's CoCo ready. The manual is in the archive. https://colorcomputerarchive.com/search?q=Dmp-130 Quote Link to comment Share on other sites More sharing options...

I saw a couple of DMP-130s still working and a reasonable price. I will look for one. Quote Link to comment Share on other sites More sharing options...
Michael Kline Posted September 9, 2021 Share Posted September 9, 2021 You're welcome. You won't be disappointed with the DMP-130/DMP-130A. Just follow your gut, when choosing which one to get. The difference between the two is +20 character/sec print speed boost with the 130A. Top serial connection speed is 2400. If you are using the SDC controller, you can add POKE150,18 to the AUTOEXEC.BAS file on the SDCX disk. Which will set the baud rate on the CoCo.

Michael Kline Posted September 9, 2021 Share Posted September 9, 2021 I just saw the DMP-132 come up for sale on eBay. It's the upgrade of the DMP-130/130A. I would recommend this one. Ask the seller to do a print test for you. It uses the same ribbons as the 130s. https://www.ebay.com/itm/373714600594?hash=item5703204292 Michael Quote Link to comment Share on other sites More sharing options...
