  1. Hi guys - Starting in January I am launching a very Coleco Adam specific YouTube channel and I would appreciate it if all of you would subscribe to help get it off the ground. YouTube requires 1000 subscribers before it will really start promoting you so I can use all the help. Besides that - I think you will really enjoy it - not your typical mail call channel or watch me play video game channel etc. The channel link is here (I have to get a certain number of subscribers before the URL gets customized). Take a look at the coming soon video! Once you have subscribed let me know what you think of the set - BTW you can also go to the channels Facebook page, Twitter and Patreon while there.

  2. Does anyone know - are the chip numbers on the Colecovision board for the VRAM the same as that in the Adam? They are the same numbers but are they same meaning? On the Adam they are:
     
     
    BIT Chip
    === ====
    0 U16
    1 U14
    2 U12
    3 U10
    4 U17
    5 U15
    6 U13
    7 U11
     
     
    Are they the same on the ColecoVision?

    There are quite a number of different sources and I certainly don't know all the options.  That said here are the one's I know about:

    1. DIY - Grand Idea Studios still has all of their Pixels Past PCB design available for free download, including schematics and gerber files.  Scroll down this page to find the ColecoVision section.  I believe the PCB fits both original classic cart shells as well as those made with the newer Opcode/CollectorVision mold.
    2. DIY - Here's another DIY option but this is limited to 16KB max and the PCB will not fit properly in a classic cart.
    3. DIY - Here's yet another DIY option.  Aimed purely at development work so not designed to fit in a properly in a classic cart.
    4. Ready to use - here's one that someone in France is selling on eBay.  Looks like this is designed to fit in standard cart shells.
    5. Ready to use - and here's Pkk's mini cart PCB options.

    Hope this helps.  I'm likely to have missed some options so hopefully others will chime in.

    I like the Pkk option since all the parts are there unless someone knows of a 27256 source


  4. I know this is probably mentioned somewhere in the 1000's of messages in this forum but I suffer from a bad case of "Oh something shiney" and I would get very sidetracked looking for it so I'll start a new post.

     

    I am looking for new blank CV cartridges with sockets, 27256 EPROM chips and case, so basically blank carts. Does anyone make / sell them or do I have to go down the route of making them myself?


  5. I have done a number of updates to the code running the archive:

    • You can now click on the Details icon for Disk and Data images to see the directory of the image (EOS & CP/M & TDOS).
    • You can now click on the Details icon for a ZIP file to see the contents of the zip file.
    • You can now click on the Discuss icon for a file and it will bring you to the Adam Archive forum and open a new message with the file name as the subject.
    • You can now click on the Find icon for a file and it will search the Adam Archive forum for the file in the subject.
    • Updates to how the site looks, cleaned up some of the code.

    So, yes it does work the Player 2 joystick but not the Player 1 joystick.  This seems rather counter intuitive in a one player game.  I would suggest switching control to the Player 1 joystick.

    I'll do that as I work on it

  7. Do the shake test - make sure nothing is floating around in the case. But it does look like a bad cable or bad connection to the TV. Don't use the 5 pin - use a standard AV cable from the monitor port - yes no sound but it lets you see if its cable versus system.

  8. I know this is a very old post but can someone point me to an example of using the export assembly code? As en example I created this simple noise (below) and can see that it is in the standard sound data format OS7 wants I am just unsure how I would go about playing it. Any example code in z80 would be great.

    Being as this is specific and I see no hardware area to post in then I will do it here.

    Can I safely assume that the Digital Data Drives Hardware is nothing more than a motor control unit and that the independent 1601 CPU that controls with BIOS instruction is mounted on the ADAM logic board?

    Unlike the Disk Drive which is an all in one device that connects to the ADAM NET.
     

    I am finding that the pin outs on the main board for DATA do not connect to the DATA on ADAM NET directly.

    Technology that makes sense in the 80's, especially when you would have redundant chips and space on the DDDrive.
    Definitely not for today especially with surface mount.

     

    Your post got lost here but yes. On the main board there are 2 6801's. One is the master and runs all AdamNet communication, the other runs the 2 data drives. All other peripherals, keyboard, printer, disk drive, have their own 6801 built in them. Any questions you have about the data drives should be referred to Howard Eglowstein who helped design them. He hangs out in the Coleco Adam facebook group (https://www.facebook.com/groups/115531017844/) - not sure if he frequents here.

     

    There is also a lot of information in the archive (http://adamarchive.org/)
