Hey Adrian, thanks for being part of SepTandy. It’s worth digging a little deeper into the CoCo3. It’s actually a pretty capable machine especially once you get into the more modern games and operating system.

@@nsm0220 Only replace caps on a CoCo when absolutely necessary. The boards were not well made and are fragile. It's easy to pull pads or traces while desoldering if you're not very careful. When doing any rework on a CoCo, it's best to clip the legs and remove the component. Then you can carefully remove the legs, doing the least possible damage. Use flux and add fresh solder to make the work easier.

@supwicha1 4 года назад

You need to get the "deluxe" joystick which has both self centering and floating capability. There was an adapter that would allow the use of atari joysticks but is hard to find. The downland cartridge probably just needs the contacts cleaned (pencil eraser). Your assumption of mindroll being for the coco3 is correct. The 512kb upgrade is an older original. You can get 3rd party upgrades 512kb-2mb that are being produced today. The "color computer archive" has every program ever made. You can also get the cocosdc to add floppy emulation and uses modern sdc cards. Nice video!

That version of Downland will not work on the CoCo 3. There is a version that will work on the CoCo 3. You can differentiate between the two by the cartridge label. The version that works on the CoCo 3 has a white label (like most CoCo 3 games do). Starblaze was the first game I ever owned on my CoCo 2. There are some keyboard commands you need to know. 1) M brings up the map. The game starts you on a clear sector, and the object of the game is to clear all the sectors. Yellow sectors are easier sectors, while red sectors are harder sectors. F sectors means there's a fuel depot there (you have to land in the fuel depot to refuel you ship from time to time). I believe there are also R sectors which house a repair depot. If you've taken a lot of damage you'll want to go to a repair depot to fix your ship. Once you pick the sector to travel to, you have to use the other key that's avaiable: 2) W will warp your ship to another sector. If you picked a sector on the map, it will warp you to that one. If you don't pick a sector, I believe it warps you to the next sector over. Either that, or a random one. I can't remember. And I agree that those old black sticks were the worst. But, it's all I had growing up. I think they were around $20 CAD at the time, while the Deluxe (a white version that had a floating mode and an automatic centering mode, changeable by switch and were capable of using 2 buttons on games that supported them, which were few) was $30-$35 CAD. I'm not 100% on those prices, though. Also, there are projects out there that will take a Sega Master System or Sega Genesis controller and convert it to the Tandy joystick port. It's just a box you plug the controller into that plugs into the CoCo Joystick ports.

@SFknight 4 года назад

Adrian, thanks for your hard work on this rescued machine. Note: The CoCo3 was always branded a Tandy, not a TRS-80, and outside of the great retrobrite work - you didn't have Color Computer 3 specific titles to demo like Rampage, Thexder, Robocop, and King's Quest III. The Tandy Color Computer 3 is a *new* platform released in 1986, that happens to be backwards compatible with previous models. (This is confusing, because there is no functional difference between the 1 and 2). The 80-column 512K CoCo3 is one of the most capable 8-bits of all time, with true multi-tasking (Microware's OS-9), and it emulates most of the Color Computer 1/2 graphics modes with its custom GIME chip. You'll find a 64 Color RGB Palette, with 16 colors available in 320x225 mode. It is certainly not an Amiga, but headed in that direction. Stop by CoCoTALK!, the weekly Saturday RU-vid show hosted by OGStevieStrow. We are CoCo all year round, and happy to help out with suggestions in the future. You'll want to try the 2020 free release "Digger III", a re-imagined Lode Runner-like game that showcases the graphical capabilities of the CoCo3, along with many other homebrew titles from the past few years from original CoCo3 developers like NickMarentes.com.

@jasondowns2778 4 года назад

The difference between the US and Canadian models is just the case: the US ones lack that stupid metal mesh in the top. Also, the feet are held in with pins. If you scrape away the epoxy, you can simply push the pins out and the feet are easily removed. This is useful for painting the case.

I think I found the man who beat me to purchasing this CoCo 3 at PRGE 2018. I went to a booth there that had vintage 8-bit computers and I asked if they had a CoCo 3 and they said they had already sold it. I'm glad it went to you though! The CoCo 3 was my first computer I bought with my own paper route money. I really expanded my programming knowledge with it, and even ran a BBS on it for about 4 years. I even programmed my own BBS Door games for it. I pretty much know how this thing operates inside and out. The CoCo line, including the 3, only had a 6-bit DAC that it used for all of its audio functions, which was all CPU controlled. So any sound generated required the CPU to do it directly. The joystick to have is the 2 button Tandy Deluxe Joystick. It also works on the Tandy 1000 line. You can take an old analog PC Joystick that uses the 15-pin connector and modify it to work with the CoCo. Besides rewiring to the 6-pin type DIN connector, I believe you need to add capacitors to the 2 pots to change the range. I know you need to do it for the Atari 5200, but don't recall if you need to on the CoCo. The CoCo 3's biggest feature was the GIME chip. It added higher resolutions (including 80 column text and a 320x200 16 color graphics mode), took care of all the MMU, which allowed for memory expansion. 32K of that 128K was used specifically for that higher graphics mode. I noticed the weirdness of the games as you were playing. Seemed like some of them had issues going right. Might be an issue with that joystick. Anyhow, there are still things being made for the CoCo 3 today, including an SDCard reader that plugs into the cartridge slot. I also want to mention that I wrote the music and some of the sound effects for a late CoCo 3 title called PacDude 2: Monster Maze by Brian O'Neill. Wrote that music when I was just 16 years old! Enjoy your new machine and learning about all it can do! I have so many fond memories of my youth with that machine.

Even though they are clearly not very sturdy, the standard joysticks were actually quite nice once you got used to them. The lack of self-centering was hard to adjust to, but they were actually pretty precise. Maze games like Pac Attack were hard to do, Donkey King and Juniors Revenge were okay, space games like Protector II and Guardian were great, and Joust, Centipede, and Robotron clones worked VERY well. Never had a CoCo 3, but I bet Sinistar, Gauntlet, and Crossbow clones would work great, too.

@darkman042 4 года назад

I spent hours and hours programming on the Coco 3 when I was a kid! You did a great job. The joystick you were using was the crappiest joystick I’ve ever used LOL! I had those at first and then I went and saved and bought the Tandy pistol grip joystick for I believe $60 at the time; it was well worth it! My parents sold all my Coco stuff after I moved out of the house. I have another one now though, and I have a gravis joystick that when I actually worked at RadioShack I was lucky enough to obtain. It had been “lost“in the stock room and it was long since discontinued when I found it.

I think it's still pretty unknown to most people because it doesn't look like its doing much but it's like SPF1000 for plastics and makes a huge difference over time! I used it on the soft top for my Jeep and the vinyl stayed perfect and it only had to be retired when the stitches literally rotted apart. I use it on outdoor items all the time and basically anything with a coat kept on it never degrades from the sun sometimes even after decades. I don't work for 303. I just wish everyone bought it so it would be easier to find (and cheaper.) One of these days you should go all "Project Farm (youtuber)" and test it on retrobrited plastic! Maybe retrobrite something, coat half and leave it in your backyard for a year. Test if retrobrite holds at all, and how well 303 helps.

@airshackretro8551 3 года назад

Great work Adrian. I never knew about the key puller tool - thanks! Also like the UV protector tip and the mirror and rotating tank. Only thing I’d do differently would be to get a larger clear bin and dip the console case top and bottom in H2O plus a 1/2 gallon of salon 40 liquid. In my experience cases look much better --uniform, no splotches- using dipping vs Saran Wrap and gel. I only use Saran Wrap and gel on stubbornly discolored keys. Almost all of the retrobriting gone wrong videos use the Saran Wrap and gel methods. Dipped my Coco2 and Coco3 without removing the bottom stickers and top ID tag with zero issues. I’ve only experienced the red color band on some older Apple badges (which it turns out are easily removed) fading when I left them attached in a retrobrite dip tank. Coco TRS-80 and Tandy badges have the colors suspended within resin, not on the surface of the badge. No need to remove them while retrobriting.

It's a mystery to me why no retro channel has never drilled down on this capability with a deep dive, because as humble as the CoCo3 was as a home computer, it had the most sophisiticated memory management for breaking the 64K barrier and had by far the most sophisticated operating system (OS-9) to show it off

I used to use rubber bands to auto-center the joysticks. There's just enough "gap" at the bottom of the stick to keep the rubber bands in place for this without interfering with the joystick action.

I made my own retr0briting lamp, utilizing 8 Cree X-QE 465nm royal blue LEDs, after seeing Adrian's video where he took apart the Phillips remote-phosphor LED lamps. The foil lined box works quite well for even lighting exposure, and only takes an hour or so.

Great video as always. If you every do a Q&A episode you gotta address what happened to your work bench that caused that rectangular mark. Every time I see it I wonder.

@marciomaiajr 4 года назад

Learned to program on a TRS-80 clone called CP-500. The teacher one day asked us to draw a swastika on the screen using the BASIC drawing functions. It was 1988 and people were less sensitive but I still remember that weird programming assignment.

@waltschannel7465 4 года назад

The big thing the Coco had going was the ability to create a multi user UNIX environment, courtesy of Motorola. I don't remember all the details, but I do recall friends in the 1980s that made it work successfully. You are right, though. The Coco was no match for the graphical abilities or game play of the C64. The C64 also had the distinction of being able to run the Geos environment, which was very Mac-like.

I still have my childhood CoCo2. I never did get the CoCo3, as I wound up buying a Tandy 1000TL instead (I still have that one too). It was great seeing you restore this one. I have 2 of those joysticks. They were $20 for two of them back in the day. I also have the pistol grip one that I bought for the Tandy 1000TL. It's MUCH nicer than the other two. Looking forward to more Tandy stuff!

@BlackEpyon 4 года назад

Never had the pistol grip joystick, but I have the "black beauty" and the Deluxe. My first computer, when I was a kid, was the Tandy 1000 HX (from my dad when he upgraded), and later a 1000 RSX from one of my grandparents when I was a teen. Still got both of them, and I've recently acquired a 1100FD and a CoCo2. The RSX is worth a quite a pretty penny these days, so I'm glad I kept it.

@roberttbrockway Год назад

It wasn't supported by Tandy/Radio Shack but it was possible to upgrade the CoCo3 to 2MB ram which was enormous on a machine of this class at the time. This is because the memory was allocated in 8x8K chunks in memory. The hardware would allow any 8K of physical ram to be allocated in to any of the 8 slots. 8x8K=64K of course. Officially you could only allocate chunks 0-63 (8x64=512K) but the hardware actually supported allocating chunks 0-255 (8x256=2048). I suspected this was possible after reading over the specs of my shiny new CoCo3 and later learnt that people had done it. OS-9 Level 2 did this seamlessly.

Always nice to see those cleaning and retrobrighting videos. Makes me calm down :) Hi from Ovesen.net

@deathproofpony 4 года назад

I'd bet that the lump from an internal screw came from someone upgrading the keyboard. I know a lot of these came from Radio Shack with a "Chiclet" keyboard (named because the keys resemble Chiclet candies) but you could upgrade them to the keyboard you have here. I was around 8 - 9 years old when we got our and my dad upgraded the keyboard not long after we got it.

@BlackEpyon 4 года назад

The CoCo 1 came stock with the chicklet keyboard, but I've seen some upgraded with mechanical keyboards. So far as I'm aware, the CoCo 2 and 3 came with the mechanical keyboards.

The Tandy computers were practically nonexistent here. I’ve read a review of the Tandy 1000 on a local home computer mag, so they’ve been imported here at least at that point. I’ve never seen one live, though. Nice work with the retrobrighting!

Believe it or not, we used a TRS 80 for work in our office many (many) years ago, before we got our first PC XT green monochrome monitor.

@xXTheoLinuxXx 4 года назад

The CoCo wasn't that well known in The Netherlands. I remember that a HAM radio shop were selling those, so back in the day I thought it was perhaps for RTTY things or so. They weren't that expensive and with everything I know now, I would have buyed one. By the way there are schematics from a convertor to make an Atari style joystick usable for the CoCo (based on the 4066 IC and a couple of resistors). It isn't that difficult to build.

@TechnoTinker 4 года назад

Both systems use simple joysticks. I converted an Atari joystick torapid fire using my Capsella set. It worked great except for all the motor brush interference, but I rolled the scoreboard over on Asteroids.

Oddly, the 68090, and 68B09e were 8/16 bit processor, in a way. They had 2 of 8-bit registers which can be used as a 16-bit register. The memory expansion was handled by the GIME chip, which switched 8k banks in and out of the processor, as well as performing other chores, such as graphics. Running OS9 Level II, with a VGA monitor shows off the computer nicely. Some older NEC multisyncs can go slow enough for it. There is a 2MB upgrade for them. I had a Coco3, and someday, I hope to get another one.

It's amazing to see how much such a tired-looking computer can be rejuvenated. My mother and aunts and grandma raised me to appreciate antiques, so I've really enjoyed all the retro computing community on RU-vid. I look forward to your videos every Wednesday and Saturday. :) My dad actually had a business class RadioShack/Tandy ... thing. I'm not exactly sure what it was: monochrome (green) monitor, with a huge, orange, rubberized RESET key that was really irresistible when I was about six. (I wasn't left alone with the Tandy after pressing the big orange button and sending a spredsheet to the beyond. Oops.) So, even though I barely used the thing, I defnitely have some nostalgia for it. I was wondering if #SepTandy was going to return this year. I'm so glad to see it back. :)

I remember the case being something like a darker grey or black, and the text being monochrome green, not the monochrome white from the wikipedia article.

As an idea, if you have a vintage box too rough to keep it can look really neat to frame portions of the box, either a detail or the main part of the box. The wear and patina on the box looks good behind a glass frame.
