  1. Maybe a OPCODE style Super Game Module could be made for the ATARI 5200 expansion port. Add some extra ram for improved homebrew games and maybe a new sound chip.
  2. The 1983 Coleco ADAM computer requires a Laser printer or Ink Jet printer with both a parallel port and Epson FX-850 emulation support. This weekend I spent several hours researching the latest 2020 printer models and none of them will work with the ADAM computer since there is no parallel port on the printers anymore. While it’s true a select few Brother Laser printers still support Epson FX emulation, all the current Brother Laser printers use either USB, 1Gbps ethernet, and WI-FI to communicate with the printer instead of a standard parallel port. The ADAM printer drivers were all made to work only with a parallel port printer. While its true there is Retro-Printer adapters on the market that convert parallel signals to USB, it is my understanding that none of them offer Epson FX emulation (As far as I am aware). Therefore the 2016 model Brother HL-L5000D will go down in history as the very last Laser printer that was manufactured with a parallel port that accepts Epson FX emulation. It is my understanding that this 2016 model Brother HL-L5000D Laser printer last manufacturing date was January 2018. While this Laser printer originally sold in price for around $176.97 with free shipping, because of supply and demand almost everyone is out of stock on new and sometimes used ones. New ones now sell in the $300+ price range plus shipping if one can find one in stock. I still have one Brother HL-L5000D Laser printer that I use with my ADAM computer once and awhile. This BD25 Female to 26 Pin IDC adapter cable for $5.95 with free shipping needs to be used to interface the Laser printer with the MIB3 and Eve SP-1 products. Even all or most of the online Amazon and EBAY dealers are out of stock on this Brother HL-L5000D Laser printer. Attached is the Laser printer spec sheet and a copy of the rare instruction sheet that ADAM dealers offered to people that wanted to configure the Laser printer for their ADAM computer.

  3. ColecoVision owners and hardware developers now have power supply options between 28.5 watts to 600 watts to go across the front expansion module interface If one has lost their ColecoVision power cord that came bundled with their Mean Well ColecoVision compatible power supply, or if one wants to choose a different model of Mean Well Power supply to use, then the ColecoVision compatible power cord is also sold without the power supply. When one purchases the high-end Gold Plated ColecoVision power cord from an online dealer, the price currently is around $15.99 plus shipping and tax. The ColecoVision power cord comes with a waterproof full color high gloss sticker that one can attach to their Mean Well power supply. Also see attached Microsoft Word document which is the instruction sheet that comes with the ColecoVision compatible power cord. One of the main reasons why the ColecoVision power cord is offered separately without a power supply. Is not just as a replacement option for those that lost their existing cord, but it gives people the freedom to choose the brand and model of power supply that they want to use with their ColecoVision. At the time of this writing there are two Mean Well power supplies that is 100% compatible with the ColecoVision compatible power cord. The 28.5 watt Mean Well GP25B13A-R1B power supply is the best quality power supply because of the excellent short circuit protection. However, someone might prefer to use the 46.5 watt Mean Well GP50A13A-R1B power supply (currently Amazon and EBAY dealers do not offer that 46.5 watt model as a ColecoVision option because of the poorly engineered short circuit protection where the power supply never recovers if there is a short between the 5 volt and 12 volt rail (see first post in thread for more details). While I do not have any plans to design a combination SGM module with built in HDMI graphics card that plugs into the front ColecoVision expansion port (A new video display processor could be used for HDMI output with micro size HDMI jack on the right side of the front expansion card). Possible someone might want to design a new expansion module with HDMI graphics card capability and using a 28.5 watt Mean Well power supply. However new graphics cards for the ColecoVision takes a lot of power and even though 28.5 watts of power is 3 to 4 times more current output then the original 1982 ColecoVision power supply, that might not be enough power. Someone one day might need 46.5 watts of power to go across the expansion port to power a new HDMI graphics card with built in SGM (the existing VDP on the ColecoVision motherboard would be disabled if a HDMI cable is plugged into the SGM and reenable when the HDMI cord is unplugged from the SGM). In small QTY’s there already exists a few 550 watt and 600 watt ATX style power supplies for the CoelcoVision (The Smurf Edition 550 watt power supply is real neat). So, my point is 600 watts of power could one day travel through the ColecoVision for some real neat fancy HDMI graphics cards and expansion modules. One 600 watt prototype power supply was made for the ColecoVision videogame system. Years ago I was hearing some people complain that one of the problems with the ColecoVision is that there is not enough power to create fancy new Super Game Modules with nice graphics cards, that excuse is no longer exists, since there is plenty of power supply options between 28.5 watts to 600 watts for the ColecoVision videogame system now. The ColecoVision compatible power cord is 18 gauge and is designed to handle up to 300 volts of electricity with more wattage capacity then any existing -5 volts DC power supply on the market can offer. In the United States there is a total of 11 different Mean Well Distributors where one can purchase either the 28.5 watt Mean Well GP25B13A-R1B power supply or the 46.5 watt Mean Well GP50A13A-R1B power supply. Click here for the list of Global Mean Well distributors around the world The 28.5 watt Mean Well GP25B13A-R1B power supply can be purchased for around $28.70 with free shipping from some USA distributors. The 46.5 watt Mean Well GP50A13A-R1B power supply can be purchased for around $41.80 with free shipping from some USA distributors. The Mean Well power supplies are available worldwide and work between 100-240 volts at 50/60Hz, and do not come with any power cord. Therefore, one needs to purchase the input power cord for the country that they live in. For the USA and North America consumers a 1 feet, 3 feet, 6 feet, 10 feet, or 15 feet power cord needs to be purchased (around $1.90 for the 6 feet model plus shipping and taxes). For the United Kingdom market this 6 feet power cord can be used for around $2.99. For the European market this 6 feet power cord can be used for around $2.29.

  4. The ColecoVision and Expansion Module #3 ADAM computer have excellent protection against using two power supplies at the exact same time When the ColecoVision videogame system was released in August of 1982, the only way to power the videogame system was to use the original ColecoVision power transformer. However, all that changed in October of 1983 when Coleco released the Expansion module #3 ADAM computer system. 100% of store purchased Expansion Module #3 ADAM systems came with a gray plastic ADAM tray that offered a tight and accurate fit when the ADAM was connected to the ColecoVision. Also when the gray plastic ADAM tray was used it is impossible to use the ColecoVision power supply and one has to use the ADAM computer power supply built into the Daisy Wheel Smartwriter printer to power both the ColecoVision and ADAM computer. Coleco did this on purpose so that only the ADAM computer power supply could be used when the ADAM computer was connected with the gray plastic tray to the ColecoVision. However fast forward to the year 2020+ and there are no more new ADAM systems and most of the time buying a used Expansion module #3 ADAM computer memory console, the gray plastic tray is missing and a hard item to find. Which means without the gray plastic tray a consumer by mistake could connect the original ColecoVision power supply and the ADAM power supply at the exact same time and turn both on at the exact same time. However, the ColecoVision and Expansion module #3 ADAM computer have built in protection, and ones ColecoVision and ADAM computer will not be fried by mistake if one turns on both the original ColecoVision power supply and the ADAM computer power supply (ADAM power supply is built into the Smartwriter printer). I tested this safety feature back in 1983 and also in 2020, and nothing got fried after several minutes of running both power supplies at the exact same time. On several different ColecoVision consoles while being connected to the Expansion Module #3 ADAM, I have verified that nothing gets damaged when using both the 28.5 watt Mean Well GP25B13A-R1B power supply and the new Apollo 400 watt Power supply for the ADAM computer, when both are connected and turned on at the exact same time for several minutes. I have tried several different combinations of original Coleco and third party power supplies for both the ColecoVision and Expansion Module #3 ADAM computer, and after several minutes with both power supplies on at the exact same time, the ColecoVision and ADAM have the built in protection to use two power supplies at the exact same time with no problems. *** Of course when the Expansion Module #3 ADAM computer is attached, one should use the gray tray with a ADAM computer power supply only. One should never use two power supplies at the exact same time, however if one does not own a dedicated ADAM power supply the 28.5 watt Mean Well power supply is powerful enough to power the Expansion module #3 ADAM computer, except for the Digital Data Drive will not function which requires a dedicated ADAM power supply. ***
  5. Yes I could use 2GB or 4GB size SD cards instead of 32GB. Its hard to find anything less then 8GB SDHC in retail stores. Getting a 256MB SD card for $2 is ideal as long as the quality and speed is good for the 100 1.44MB 3.5 inch floppy drive images. One can have a pack of 10 256MB SD cards for around $20-$25 that is equal to 1,000 1.44MB floppy drive images. Personally for important things I use the SanDisk Extreme Pro 32GB SDHC with my Coleco ADAM computer, and I have just learned to live with the wasted space issue of 140MB maximum for each SD card.
  6. I just recently sent for a sample of a 256MB SD card from the Onefavor company. This 256MB SD card is made in the country of Taiwan. While the construction quality is good and it works in the Coleco ADAM microSD Floppy Drive emulator (when using the full size third party SD card reading hardware device), the one sample I received is too slow with a Windows writing speed of around 0.5MB/s. Here are some more detailed test results of 3 different SD cards. 1. The Onefavor 256MB SD card has around a 0.5MB per second transfer rate under real world conditions. To move 140MB of data from a Windows 10 PC to the Onefavor SD card took almost 4 minutes (3 minutes and 52 seconds). 2. On a Memory Partner 256MB SD card has around 6MB per second transfer rate under real world conditions. To move 140MB of data from a Windows 10 PC to the Memory Partner SD card took around 24 seconds. 3. On a SanDisk 32GB SDHC card has around 41MB per second transfer rate under real world conditions. To move 140MB of data from a Windows 10 PC to the SanDisk SDHC card took around 3 seconds. I am looking for a 256MB SD card that would meet or exceed the speed performance of the Memory Partner 256MB SD card which is 6MB/s for some samples and 5.5MB/s for other samples. The Memory Partner brand is still the best 256MB SD card on the market for speed. The problem is some of the Memory Partner SD cards have to be reformatted when they come from China since they have viruses on them. Also some of the Memory Partner SD cards have bad lock switches and need to be tossed in the trash when they arrive. The construction quality of the Onefavor 256MB SD card is the best, however the card is too slow with a real world transfer speed of only 0.5MB/s. Companies no longer make SD cards under 2GB in size, and one has to find old stock of new 256MB SD cards for the Coleco ADAM microSD Floppy Drive Emulator. Sure one can use a name brand high-end SanDisk 32GB SDHC card that is made in China in the Coleco ADAM microSD Floppy Drive Emulator, however the problem is because of the firmware issue, only a maximum of 140MB of space is useable, and a lot of empty space is wasted. The ATARIMAX Ultimate SD Wafer drives, and Harmony Encore SD Wafer drives can use the entire 32GB of space on a SanDisk 32GB SDHC card. I wish the Coleco ADAM microSD Floppy emulator would use the entire 32GB of space on a SanDisk 32GB SDHC card, then I could fit the entire ADAM computer collection on one 32GB SDHC card. If the Coleco ADAM microSD Floppy Drive Emulator had another button that allowed one to jump back and forth 100 1.44MB disk images at a time and a firmware update then it would be possible to use more then 140MB of space. However, there is no plans to issue a firmware update or release a new and improved Coleco ADAM microSD Floppy Emulator. So one has the choice to use lower quality 256MB SD cards with their Coleco ADAM microSD Floppy drive Emulator or to use high quality up to 32GB SDHC cards with only 140MB of useable space.
  7. If it was technically possible the best use for the ATARI 5200 expansion port would be to add a graphics card with a HDMI output. The expansion card would disable the onboard ATARI 5200 display processor and turn on the new video display processor in the graphics card that offers HDMI output for modern displays. A new high-end regulated third party power supply would power the ATARI 5200 console and external HDMI graphics card.
  8. I am happy using the EVGA fully modular ATX power supply with my Commodore Amiga and the Atari 130XE computer. The EVGA power supplies puts out a nice stable voltage on minimum loads even way below 0.1 amps. In fact, there are people with Commodore Amiga’s that have been using a Amiga power cord connected to a ATX power supply for several years. I like the full modular ATX power supply concept since if in the rare chance a power supply goes bad one just unplugs the Amiga and ATARI cord from the ATX power supply and plugs the cord into the exact brand and model of EVA power supply. The power supply already has all the required safety certifications. If one makes a power supply from scratch there are sometimes issues with reselling the external power supply like getting the required level VI and FCC for USA market and CE for Europe safety certification. I like the fully modular power supply concept instead of separate power supplies for every computer and videogame system in existence. It is awesome that each year there appears to be more and more power supply choices for consumers.
  9. Amazon and EBAY dealers in the United States now have both the ColecoVision 17 Watt 3.4 amp USB Power Supply kit in stock and the new 28.5 watt ColecoVision compatible power supply. Now ColecoVision owners from around the world have a choice of two different power supplies to choose from.
  10. The videogame crash of 1983 was a huge recession in videogames and some home computers between the years 1983 to 1985. There is a possibility that in the years to come for the 21st Century there might be another bigger and larger bubble that might burst with a much larger videogame and computer crash (recession). The next videogame recession would most likely not only effect modern computer and videogame systems but also those companies that support classic videogame and computer systems from the 70’s, 80’s, and 90’s. If another videogame/computer crash does happen hopefully it would only last a few years. Under the right conditions a videogame and computer crash could last 10 years and become a videogame and computer great depression.
  11. And the evidence to support what you just said is that Coleco released many of the most popular ColecoVision games in a ADAM version with some major improvements since even Coleco knew improvements could be made.
  12. It should be mentioned that the Col USB plug works flawlessly with some USB chargers and cables as mentioned in the following thread for the ColecoVision 17 Watt 3.4 amp USB Power Supply solution (and that is why some dealers only sold the product with a high-end USB charger and USB cable). However, that being said the 28.5 watt Mean Well ColecoVision compatible power supply is a better quality solution at a cheaper price. But since many people are attractive to USB they most likely would prefer that version that sells for around $84.99 on EBAY when one can get stock. https://atariage.com/forums/topic/287788-colecovision-17-watt-34-amp-usb-power-supply-solution-user-review/
  13. The ColUSB is a very popular power supply solution that is still being sold by some dealers when they can get stock. I like your idea of making an improved version that accepts up to 25 volts DC and requires USB 3.0. The latest USB chargers can output 20 volts at 5 amps (100 watts). People are attractive to USB power supply solutions for their ColecoVision and just because it is USB it might out sell the Mean Well power supply. Personally I prefer bypassing USB power supplies completely.
  14. I am glad to hear that you repair the original ColecoVision power supply. I wish they would have made some screws on the power supply like other systems. One has to break or pry the glue open and then re-glue the plastic case shut again once the power supply has been repaired.
  15. Today the best way to play videogames is with a DLP projector or a OLED flat panel that has absolute black levels like a CRT. Over a decade ago CRT TV/monitors went out of production. One of the reasons was consumers preferred the bigger size flat panels with less weight. I have also read that due to some environmental laws that CRT displays are not allowed to be manufactured anymore. If this is true then this would explain why CRT displays completely disappeared from the market if its against the law to manufacturer a CRT display. It has been well documented that one of the main reasons why Plasma flat panels are no longer made is because of environmental laws stating how much power consumption a flat panel screen is allowed to use. No one makes plasma flat panels anymore and they were replaced by OLED flat panels that suppose to use a little less power consumption.
