    Yes zippiz, if the Team Pixelboy release on cartridge of Zaxxon Super Game works on your Adam, then part of the Adam Logic Board (the extra RAM that it provides) is functional.

     

    Always safest to have the power off when plugging in a controller to one of the DB9 ports... more so on a real ColecoVision than Adam, but best to play it safe so as not to damage the Controller ICs on the PCB.

     

    Digital Data Packs should only be inserted in the Data Drive after power is already on to the system AND always remove the data pack/tape before powering off the system. Also, don't leave a Data Pack in the drive for long periods of inactivity when the system is poweredon because the Drive will constantly be working to keep the tension on the DDP/tape which adds a lot of wear and tear and can cause the controller chip on the Adam Logic Board to overheat... they don't all have heatsinks on them as I have found.

     

     

    Ok, I did not get that it was the a special version of Zaxxon, so I guees no I do not have any way to try out if the black screen is faulty memory or anything else. :(

    Thanks a lot for letting me know about turning the system of if switching controllers etc, coming from Commodore and Atari I have never done that before, good to know.

     

    I will try again to open up my Adam, and this time remove the all the IC that I can and hope for my Adam to boot up. Would be so cool to get it in working state again.

    Great to hear that things worked out re. the power supply and that at least you have the ColecoVision portion of the ADAM working.

     

    What exactly is the issue you are experiencing with the ADAM side of things? If you have one of Team Pixelboy's Adam Super Game conversions to cartridge (Zaxxon, Subroc, etc.), you can use it to test if at least the extra RAM provided on the Adam Logic Board if functional.

     

    Once you turn on the Adam, power is supplied to the entire system (Adam Logic Board and CV Delta Board) until you turn off the system. The two boards work together at all times no matter what reset switch is pressed. So... always turn off you system when swapping carts or plugging controllers into the DB9 ports and never leave a DDP in the drive during power on/off.

     

    Yes I do have Zaxxon here somewere, I bought a lot of games (50) but have just tried one or two so far. Need to try it out a lot more, so if Zaxxon works the extra ram from the Adam is working as well?

     

    Ok, good to know I belived the power to the Colecovision was of when switching to Adam. I need to build a switch, not entirely sure that I dare to use just the power switch on the PSU.

    Did not know I have to turn power of to plug in conttrollers, or/and the DDP. Might never get a chance to use the DDP, but still hoping! :)

     

    Also have a broken Colecovision that I need to try to fix. My first time with a Colecovision, I always belived the Colecovision was how the Intellivision looked in US.

    Hey Fredrik,

     

    The pin out at the ADAM which is the male side is the following,

     

    Pin 1 +12v

    Pin 2 +12v

    Pin 3 +5v

    Pin 4 -5v

    Pin 5 Ground

     

    No need to worry about pins 6-9

     

    So when making you're female db9 plug to go into the ADAM, I'm guessing you know Pin 5 is at the left all the way to Pin 1 at the right.

    PM SENT

     

     

    Thank you, my Adam is now working!

    Well, almost at least the Colecovision section of it is, the Adam was dead when I bought it. Was hoping for it to start up, since I was opening up the other day and lifted the IC a little bit. Might try to take it apart again and remove and attach them fully this time. Other than that I have no idea what to try.

     

    Well, anyhow many thanks for the info!

     

     

    BTW, does anybody know if switching to Adam with the reset button counts as turning the Colecovision of, so that I could switch cartridge in the Adam-mode then switch back to Colecovision?

     

     

     

     

    Send rey_1178 a PM seeing as he makes an Adam Power Supply and would be the best person to get the right info from on this forum.

     

    When I get home tonight, i'll see if I got any diagrams as well.

     

     

    Thank you, that was a great tip, and woked out pretty great! :)

    This is the info I did find...

     

    Pin 1 = 12V BROWN
    Pin 2 = 12V RED
    Pin 3 = 5V ORANGE
    Pin 4 = -5V YELLOW
    Pin 5 = Ground GREEN
    Pin 6, 7, 8 = Serial Data Clock, Serial Data, Signal Ground?
    Pin 9 = No Connection

     

     

    BUT, when I compare this to the inside cables in my Adam its

     

    1 = Orange

    2 = Yellow

    3= Red

    4= Blue

    5= Green x 2 (two green cables)

    6= Black

    7= Brown

     

     

    Plese, anybody I really want to try my Adam out and do not want to risk burning it. :(

    Please NEVER replace the original. If refurbished it should last as long or longer than a replacement.

     

    If the original power switch is:

     

    1. Desolder and remove

    2. dissemble

    3. cleaned with rubbing alcohol and q-tip to get the old grease off

    4. deoxidize contatcs peferably with D100 Deoxit

    5. regreased with a high quality dielectric (simply means non conductive) grease.

     

    I would recommend lithium.

     

    Here is a tube for $5. You can get grease in almost any big box or automotive store.

    Agree, I don't understand why everyone is replacing, just refurbish the original. By the way, did for the first time today, you do only have to pinch the expanded metal on the outherside of the power switch, and desolder the metal shielding for the switch (two spots). No need to remove the whole switch. :)

    I just bought a Colecovision from Ebay "as is", spend the day making a psu for it but when I turn it on the picture is just bars. I can hear the game starting, and I can connect a controller an start to play but the picture never changes at all.

     

    So what do you guys think, might this also be a dram error? (I did check, and restored the power button).

    Hi

     

    I just bought an Adam computer from US, and it arrived yesterday.

     

    It's a great machine, but I have no way of trying it since I do not have the printer. So I want to build a power supply from an ATX I have.

     

    I will use a 7905 to convert the -12 to -5v but I do really also want to add a filter to this so I bought this kit for the 7805 but want to use the 7905 instead.

    So does anybody here know what I have to do, just turn the capacitor and the other component 180 degrees? (since it now negative voltage).

     

    http://www.ebay.com/itm/131369840096?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

     

     

     

    Did anybody try to replace the RAM in Adam similar to the RAM replacement you can do to Colecovision, and then you would not need the -5v at all, or are there any other component in the Adam that requires -5v?

    Hi

     

    Hope my first post here don't turn out to be a really stupid one.

    I have a Colecovision and Adam on its way, first time owner.

     

    But, at least teh ColecoVision is damaged, and my guess is its the ram. I wont get any power supply with either of them.

     

    Well, so here is my question. Will the ColecoVision still need -5v after doing the ram-mod? Been trying hard to find this out reading in this forum but still not sure if the controller chip still needs the -5v?

     

    If not, I thinking about just using a simple hdd power supply for the ColecoVision. (dont know how to power the Adam computer yet, it should work so maybe try and find a old AT-power suppply or try using a 7905 to generate a -5v.

     

     

    So would this work a power supply after a ram mod?
