  1. I'm looking for someone to do some repair work on a 1977/78 TRS-80 Model 1 (Level 1) and a Coleco Adam. The TRS-80 needs a key replaced (I have a spare keyboard to pull parts from) and has an issue with the video sync (I think). The Coleco Adam is having some power issues, but I think it's coming from the console itself as it won't power on when one or both of the cassette drives are plugged in, but the power light comes on when they're disconnected. It also has no video, as far as I can tell. I'm more flexible with the TRS-80, since I already have the motherboard removed from the cabinet and could easily ship that, but I'm hoping to find someone who already owns an Adam so I can ship just the console with the data drives installed. I do have a spare printer motherboard I could send as well if needed, though, but it would be more expensive. Anyway, if this sounds like something you could do, let me know and we can discuss pricing. Thanks!

  3. I would like to open the discussion on EDTASM+ and your experience with it. I realize this is an Atari forum, but I'll take any input I can get I have a CoCo 2 with 64K and I'm curious how large my applications can get with it. I found this manual online: http://www.colorcomputerarchive.com/coco/Documents/Manuals/Programming/EDTASM+%20With%20ZBUG%20%28Tandy%29.pdf It's been helpful as it references EDTASM+ cartridge version. However, due to the time it was written, it goes into more detail about the 16K and 32K versions. I'm curious if it has support to take advantage of the 64K machine I have. I get that this is more than antiquated, but I have a feeling you understand why I would want to learn this. Thanks in advance to anyone who wants to discuss this.
  4. I am selling my Atari 400 computer and Atari 410 Cassette Writer. They can be seen here: http://www.ebay.com/itm/Atari-400-Vintage-Computer-and-410-Cassette-Read-Writer-/221955724720?hash=item33ad9795b0:g:ITMAAOSwNphWXLvH -ArdsleyTank
  5. I have several of the CoCo's but I always wanted an original model 1. Now, that dream is finally a reality. I also bought an original monitor that should be here in a couple weeks. Other than a Radio Shack cassette drive, what should I get next? I just want to play some old-school games and do a little BASIC programming. Suggestions appreciated!

  7. I finally got my hands on a nice looking TRS-80 model I computer after years of looking for one today. Have had two monitors for years and an extra power pack, but no computer. This one is very complete with the manuals and looks pristine inside and out except the screws holding the case together have rusted for some odd reason. No signs of moisture on anything but those screws, must have been in a storage unit for a while. Anyways, the monitor is in good shape, but when I boot the computer up I just get garbage, diagonal lines across the screen and what looks like bit's of letters like it is trying to boot up. I pulled the unit apart and it looks fine inside, possibley even upgraded to level II from what I can tell. I found four adjusters on the board and fiddled with them a little, but no improvement. Anyone know what is causing this? If I have to, I'll get a picture tomorrow.

  14. I have three very clean CoCo 2s for sale and a painted CoCo 1. I take them apart and clean everything. Next to buying new, this is the next best thing. I have sold countless CoCos and test each one. https://www.ebay.com/itm/263576669245 https://www.ebay.com/itm/263576711109 https://www.ebay.com/itm/263576713816 https://www.ebay.com/itm/263576719045
  15. Looking for Tandy Color Computer Games and accessories. Buy or trade, I can consider either. PM me if you have any you would like to sell, thanks! (images are not mine, used for reference. )
  16. Hello everyone, I had an interesting trade in today and frankly I have no idea what this stuff is worth or if any of it is truly complete or collectible. Ebay is amazingly scarce on a lot of this stuff and so I turn to the experts here to help me out and tell me what I have. I don't normally take trades like this since I am dumb about classic computing and have no business with these items which I openly admit, but it was just so much stuff and a lot of it was in awesome condition on the inside. The boxes were mostly beat to crap, but a lot of these machines were still in the plastic on the inside. It also came with a bunch of accessories that I had no idea about. The only thing this lot came with that I understood was 4 sealed atari 2600 games and that was the clincher in taking this stuff since I knew those were worth something. I just hope that I have some cool things here that can help flesh out some people's classic computing needs. I have attached pics of everything and i'm hoping you kind people can help me out and tell me what I have and possibly how rare it is if at all and if it's worth anything. I would be more than happy to work out a deal through here with someone if any of you are interested in anything in the pics. I don't post much here, but I am a known retro seller on the internet with a retro store in Portland Oregon and come recommended from rick weis and had a booth at the retro expo in portland. I just know that resellers don't usually have the best reception on these forums for good reason, but I hope you all can give me some help. I truly appreciate any feedback on this stuff. Maybe I can get a few more deals under my belt here as well. If there are any questions or more pics are needed let me know. I tried to take as many informative pics as I could so that there would be little guesswork, but am more than happy to take more if needed. Thanks everyone. Some vic-20 accessories and TRS-80 items Here are the computers themselves in some box shots No Box Now for the open box shots where you can see the amazing quality of the items on the inside. We're talking either never used or very lightly used. The only machine that isn't in the original plastic
  17. Looking working double density board and lowercase character generator chip for TRS-80 model I.
  18. I have a bunch of The Rainbow magazines for the Color Computer for sale. See... https://www.ebay.com/sch/colorcomputerstore/m.html?_nkw=&_armrs=1&_ipg=&_from=
  19. I have been trying to collect the four original models of the TRS-80 computer line and I am nearly there! Only need to save up and find a working Model II to complete this little collection. So far I have a Model I that works, but the two monitors I have will not stay stable on the verticle hold. Probably the old TVs turned monitors. I have a Model III that boots fine, but the heads appear stuck in the disk drives. Also found a model 4 Portable in good shape, but same issue with the disk drives. Still, this is further than I have been and at least they take up a bit less space than console radios! And yes, I even have a working TRS-80 program recorder sitting in this picture. Found it for $5 thirteen years ago to listen to my music tapes on. P.S. The main issue with the Model I was the horzontal hold on both monitors was way off. Now to just get that vertical in and maybe tweak things a little better.
  20. Well I finally got my Coco 3 today...Hooking it up to my TV & firing up Super Pitfall gave me the biggest wave of nostalgia I've had in a while ..It was like I was transported right back to the floor of my parent's living room in the late 80's lol I had the black, non self-centering joystick though when I was a kid, but this time around I got the Deluxe model. Super Pitfall & a couple other games played with no problem, but others like Thexder & Rad Warrior I couldn't get to work right. I read the manual online about the switches on the bottom & dials on the top that I was never familiar with, but no matter what I tried, nothing seemed to help. Sure it's one simple thing I'm overlooking. For Thexder the button is making him jump, but the joystick does nothing...Same with Tetris, the button drops the tiles down but nothing else works...on Rad Warrior the character just runs on his own until he gets stuck in a corner where he proceeds to run in place lol..Same thing with a couple others I've tried so far, button works but joystick doesn't...yet there are a few games where I have no issues Another thing...I was disappointed to see vertical lines on the screen on my flatscreen with the composite input. They're not bad enough to where it's unplayable though at least, but I could def do without them...I haven't tried the RF yet, but I imagine it would look worse. The picture from my modded 7800, Genesis & Super NES composite outputs is clear on the other hand....But my NES, when I 1st hooked it up to this TV it appeared to be fine..Shortly after the AC Adapter went bad (Generic universal NES/SNES/Genesis plug)..Once I got a replacement (Official NES) I now get thin wavy lines in the background of every game I happen to be using the same RCA cables on the Coco 3 that I was just using on the NES..But the chances of the cable itself being the problem would be too good to be true I'm sure...I have no others ATM, so no way to test another set anyways..Can anyone shed any light on any possible solution? I don't want to get a seperate CRT TV or play on a monitor (nor have the space if I wanted to) Thanks in advance, Steve
  21. I am having a problem with my TRS-80 Color Computer 2, it will not load cassettes. I just bought a new cable for it on Ebay, as i did not have one. The seller said it was made himself, it was hooked correctly into the cassette recorder, but when i try to load a cassette, it just sits there and does nothing, the motors do not run at all on the player with it hooked up, unless i hit play on the recorder, and it still will not load! any ideas?
  22. Hi All, Looking for a little help from folks who are really good with circuits... I've had a TRS-80 Model III for a few decades. A bunch of keys on the keyboard stopped working, so I assumed they were dirty and went through the process of desoldering/cleaning/resoldering all of them, only to discover that the same keys still don't work. I then found the Model III service manual online, which has a diagram of the keyboard interface on the CPU board. See the attached PDF for the diagram. From the diagram, I discovered that lines 9, 10, and 15 account for all of the keys which do not work. So the problem is most likely on the CPU board and not the keyboard itself. The problem is, I'm no electrical engineer and I might be a bit out of my depth here. Looking at the diagram, it looks like each of those lines is connected to a resistor (RP5) and maybe a diode (D0A, D1A, etc.) but I don't know if I'm even reading that correctly. I can't really tell if those are all discrete components or if some of them are the same component shared by multiple lines, though. So I'm wondering which parts are likely the culprit here, and how I might locate them if I pull the CPU board from the computer. I tested the 20-pin ribbon cable end-to-end and it seems fine, so the issue isn't in the keyboard or it's connection. It definitely seems to be something on the CPU board based on this diagram. Thank you! trs80-model-3-keyboard-diagram.pdf
