The last 3 CBS, 2 coleco, 2 very rare Technovision (i think) and 2 cheap Mattel's because they never work on my junior, happily i do own a Retron77 where Both games gladly work. Not sure if they are really cheap but i bought Them relatively cheap so i guess i am correct... Long story short, the last blast of my collection... What follows are single Carts, prototypes, homebrew(s) and well... Others... PS: notes now Both Mattel's are almost notn readable but these are frogs and flies and kool-aid-man.

Here are the latest Collectors Lists for the ColecoVision and ADAM Computer systems. Please note that I am not maintaining Rarity ratings anymore, so what you see listed should only be used as a general guideline. There are still many items to add to these respective lists (especially Homebrew items), but time hasn't been on my side of late and they will have to wait until next year's update. Enjoy and as always, please feel free to share additions, corrections, thoughts, etc. in this thread.

I've been collecting Coleco Adam stuff for years, but never really used any of it. So it's time to pass my collection on to someone who will enjoy it. They can all use some cleaning, and maybe retrobrite. Local pick up only Cash or Venmo only, can't take PP for these. $600.00 Click on picture to expand image. Comes with a disk drive, tested today. Drive and original power supply. Also comes with a microSD floppy emulator Power Supply 4 Coleco Adams, 1 has a drive that is a little squeaky, the last one doesn't power up and is missing drive and cover. 3 Coleco expansion module 3 Adams. All work, one is missing the extra drive cover. One has a door that won't close but you can put the DDP in it and can still loads. 3 working keyboards, one is missing some keys 3 non-functional drives 2 x sound blocks for printer 2 x printer ribbons, don't know if either or both fit the adam cleaning cloths for printer rods AV cable Adamnet cables Joystick holders RF shields for DDP tray for holding Colecovision and Expansion Module 3 Autodialer Boxed DDP Memory Expansion? 2 x Microfox Technology IDE card. One has a bad GAL chip, there is a replacement chip that hasn't be installed Boot cartridge for IDE card. Project Name By Line Version 2 - graphic Utility Cartridge. I just dumped this as it hadn't been 3 Printers, not really tested. Powered them on and they seemed to react. Not sure if they work correctly or not. All DDP except Zaxxon, only Zaxxon disk has been tested. 8 boxes of DDPs. Haven't really tested any of these, just used a few to test the systems. So I have no idea how many work or what is on them. Have Fun! Disks Boookes Miscellaneous document, instructions, catalogs, etc. -

RGB mod: Here is a link to a thread in the ColecoVision Forum: http://atariage.com/forums/topic/232809-new-rgb-colecovision-mod/ Here is a quick video I made with cell phone showing the RGB mod connected to the Framemeister and the HD Video Converter on a Vizio LCD TV. RGB mod outputs awesome video signal and dual mono audio through a discreet 8 pin mini din jack on the back of the console. This mod was designed to be used with a RGB to HDMI scaler. The XRGB mini Framemeister and the HD Video Converter (sometimes referred to as Panlong) are my tested and recommend scalers. They provide awesome picture quality on LCD/LED TVs. This RGB mod should also work with any monitor that accepts a 15khz video signal, although I have not tested on any monitors and cannot make any guarantees. https://www.amazon.com/Panlong-Converter-Scaler-Coaxial-Consoles/dp/B00D86UYBS/ref=as_li_ss_tl?ie=UTF8&qid=1420692028&sr=8-1&keywords=scart+hdmi&linkCode=ll1&tag=atariage&linkId=6f51c402c5548c619cfeae00ff569b61 I have also seen them on Ebay for around $43 with free shipping.

Hello everyone, I have a problem with my colecovision. It worked fine when I used it last week, but when I tried to play some pepper II the screen started messing up. I've attached a video. Does anyone know what causes this issue? It's not the RF cable. VID_20210215_224823.mp4

Does anyone know the volts, milliamps and the polarity of the original Gemini power supply? Also is it DC or AC?

This is a bit of a followup to a post I already made about a power supply I was working on. Anyway I was able to get the adam to run by just running my own wires to the db9 connector instead of using a serial cable. I now have the problem that the thing only runs if I hold down one of the reset switches and even then the picture is noisy, and the channel 3/4 switch seems to do nothing. If anyone knows what's going on here let me know please. I want my desk space back

So im attempting to make a psu for my adam. I bought one that somoneone on YouTube recommended and followed a pinnout I found. When I tried it I got a black screen with some static. Checked the voltages at the supply while plugged in to the adam and they seem normal. Checked the voltage at the end of the cable and they were the same. Checked the voltages on the other side of the connector inside of the adam and they were low (like 10v, 1.7v, -6v) not sure what's up if the connector is bad, checked a few of the pins on it and they didn't have high resistance. I don't know if this is normal or not or even if the computer works, so any help is appreciated.

Technical question that needs insider info. I have several versions of the TI 9928 book including an original I received in 1984 just by calling Texas Instrument. The way I understand it is the Chip itself has a basic type of BIOS. I also understand that this is locked inside the Colecovision. However, a...Could a jumper unlock it (doubtful) but b... Is this bios a standard generic bios or one written for the Colecovision environment itself. Knowing a bit about chips that most of these are write once but some if you add voltage on certain pins they can be written to. I know this is above a lot of peoples pay grade but hopefully one of you knows just enough that may lead to more information. Maybe something Howard Eglowstein can answer if he pokes his head around here on occasion. I know he does over on the ADAM Facebook page.

While most would agree that DK for the INTV was not the "best" game for the Intellivision back in the day, you have to give credit to Coleco and CBS for getting it out there in many forms. Not including the excellent new DK Arcade which was recently released, I am aware of 10 different box variations for this videogaming work of art. I have nine of them. ( I may have a problem. ). The five across the top are CBS releases, as you can see the first three are French, English and German language variations, the fourth one is the UK PAL version, then the fifth is the multi-language International version. The bottom four are Coleco versions, two English and two bilingual English/French Canadian versions. The one I'm missing is a German version of the fourth box on the top row with the angry looking DK throwing a silver barrel. To the best of my knowledge, (and off the top of my head), DK might just hold the record for box variations for this system. After 12 years of collecting for the Intellivision, I've got to find something to keep searching for.

Here is an early version of the Tripplin Game (Tripple-Trippin) FROM SCRATCH (C) 2020 Will be 3 classic games from the 80's v3.5 mind you I am on v19 working on bugs and polish. This plus the 2 other games built into later revisions of this rom. If I gave you v19 that would give away too much of the mystique. So, I wanted to get your input. If it works on real equipment because this seems to be an issue with our games right now. Speed, stuttering, NTSC/EU if you can manage it. There are no menus, no skill levels to set but if you press 1, 2 or 3 on keypad #1 during game play you activate Live Tiles (tm) I have worked out the mines blowing up each other and I am not sure about everything that works and not on this version. Shooting mines makes the score go haywire in this early bugged release. 2 players are working. Shooting each other has been disabled. No sound or music. The play field is 100% random when the menu system is running because the seed value changes while waiting for you to select a game. In this version it jumps strait to the game for testing purposes so the mines stay the same after each reset. But, here you go for now. 100% Assembly Language 6000 lines of hand typed Code Tripplin v3.5.rom

I would almost be ignorant to believe that this questions has never been asked. Has anyone attempted to make a Colecovision cartridge with battery back up. I am researching my options as far as how large I can make a game. We have seen the limits of the Colecovision in our games. A quick shoot 'em up, what's your high score but there is another reason why that is all we ever had and no save game feature on the Colecovsion. Shove the cartridge in, play the game then put your cartridge back on the shelf. DONE! I have no issues with creating a decent size Zelda-ESK adventure game with a feature to save your progress. I mean seriously... If I have to be limited to a password system then so be it but I would rather have something that you can play till you are tired, save your game then turn it off until you are ready to progress. So lets make it happen people. BTW, I know this can be done with emulator save states or better yet make a full ADAM game using file BIOS features saving to data pack or disk but how much more can we do with cartridge based games. Let's not allow the TI 994A to be the only hobby machine from all these years. Heck, I have seen more done on the old TRS 80 than I have for ADAM...

So far it is pre-animation and a map with room numbers but whomever wants to give feedback is welcome The offsets have not been tuned so you might get stuck in a wall. If you stay within the green lines you should be fine. Do not go left in room 0, that is INFINITY!!!!!!!!! You may get the same result at the end in room 128. I would like to get the approval of the original author but if that is not the case I can tweak this to be an entirely different game. All 129 rooms are there 0-128 Enjoy !Shamus v2.5.rom

Polishing up my game and I am running into small issues that some of you brains might be able to help with. One, I am running out of time because of Christmas and Grand kids flopping about. Two, I am running out of time because of Christmas and Grand kids flopping about. With that I would ask if anyone in the community has an accurate count down timer like that featured in Donkey Kong, Blasto or your common core game with a count down timer. I have two players competing for merchandise on the screen with a count down so the higher score wins after time out. My routines work but they are iffy at best so if there is a professional formula that also shows a 3 digit display anywhere on screen Please, code must be in Z80 assembly. Tony Cruz gave me some insight on BCD and now I am thinking I was pretty dag on good with my coding, I have done some things you shall see, however this went over my head and just did not work the way I thought it would. A simple 3 digit display timer that counts increments of 1's from 199 to 0. TIA always.

Hi, I've recently come across two Coleco Gemini consoles. I got one working no problem, but the second won't display any Picture. Powers on as my TV goes to a solid grey screen. Known good power supply. Known good game Known good AV Chord. Tested all the above with a working Gemini and it works very best, so the problem is isolated to the guts of this console. I checked the power input and reinforced the solder on it. I checked the voltage regulator and it seems ok. I've also re-flowed the solder to the cartridge slot and all the chips. I think the RF Modulator is bad but I'm not sure how to test it with my multimeter? I removed the shielding from it to get a good look inside and re-flowed all the joint to all the components but nothing has changed. Also, is there a way to confirm if a chip is bad with a multi-meter? I searched on here to find any threads with a similar issue and there's not much for this console. What I've dug out was some people mentioned that its made with off the shelf cheap parts and the solder is notorious for failing. So those are the issues I tackled first but still the same grey output on the screen. When I wiggle the channel select it does have a effect on the screen though. At this point my guess is bad chip(s) or bad RF Modulator. I guess it would make a good candidate for a Composite mod, but I've never done it before and not even sure if the kits for a 2600 would work on this thing. I've searched for anywhere that would sell parts for this thing (especially the chips) but that too seems pretty hard to come by. I can provide photos if anyone wants to take a stab at it. Any help would be greatly appreciated. Thank you.

Now that I am a month and some change away from releasing my work I would like to call on those of you that have already traveled this road. I can print my own boxes but would rather have someone who already does this and has the equipment to handle at least 100 units. I am in no way expecting my game to be popular but there may be some out there that would want a physical collectors version with a proper box and manual like the old days. Being as I also want my work to get out there and not charge a fortune which doing this myself would do. So please PM me with ideas and contacts. Also, this is related to my programing work but may not be directly programing so if anyone wants to transfer it to a proper place in the thread please do so.

In order to contribute and help budding Coleco/ADAM programmers I intend to share various code snippets that will help you along. I have found over the years that specific details are hard to come by so I will help where I can but I am not going to teach you Z80 assembly language. It is not as hard as you think and can look intimidating at times but don't give up. If you use assembly language you will gain speed and space over any higher level language. (my opinion you may feel different) That said. Have you ever wanted to know what pattern your sprite is over or just wanted to know what pattern (or color) is at what position on the screen. Maybe you want to build a wall that you do not want to pass through so your wall is pattern 45. Well, you can say if a = 45 then do not pass. In assembly that looks like this LD A, ???? (magic number) CP 45 ; (Compare) or if A = 45 JP Z DO_NOT_PASS ; If yes then jump to Do not pass routine if no then continue on. ; Continue Journey code.... RET ;(Return from where you called from) DO_NOT_PASS: ; Do not continue moving through pattern. RET ;(Return from where you called from) But how do you get that important magic 45 or other value into A Well, in another post I will show you how to set up graphics but for now we will just say it is there. For now it is sitting in GRAM, VRAM....The Ram connected to the TI9928 Graphics Chip. The way Colecovision works is that the Z80 uses Ram and the Graphic Chip uses Ram so in order to get to the 16k Graphics Ram you have to go through a port which kind of sucks because it creates a bottle neck. However the Z80 is mighty fast so we can get away with a few things and scrolling is not one of them. That does not mean you can't have scrolling games, it just means they won't look as smooth as modern systems. Because Coleco Sprite Y and X values range from 0 to 192 Y and 0 to 256 X we have to divide them by 8 to get the proper Rows and Columns In the Coleco world we have 32x24 screen patterns (768) Mathematically it all adds up and divides equally as you would expect in the computer world. The routine is actually 4 parts. 1st is to divide by 8 and get the Rows 2nd is to divide by 8 and get the Columns 3rd is to send (OUT) to PORT 0BFh. 4th is put that returned value (IN) 0BEh into A Port BE VRAM Data (Read/Write) Port BF VDP Status Registers (Read Only) I do not want to get into the AND's and PORTS right now because that is information overload and a distraction so for now I am sticking with minimum code.

Does anyone have example code for a minefield explosion or similar? IE you have one mine explode and if it is next to another mine then that one will explode which triggers any mines next to that one explode and so on. Here is another issue I have. Using negative numbers refuses to play ball no matter how many times I ask it. I have a set of numbers in a loop that goes something like. -33,-32,-31,-1,1,31,32,33 It works fine but when it gets to 1, 31,32,33 it goes bonkers. But if I get rid of the - signs it works but then the negative portion is jacked.
