  1. Not a big CP/M or T-DOS user as well, but I would stick with the T-DOS install programs that are on disk #1 to create your system disks and in the process, the system configuration is created. If you will be distributing a program for others to use, then best practice is to remove additional hardware from the ADAM to create a bare bones configuration of say one Data Drive and Disk Drive or supply the proper T-DOS install file for the end-user to configure according to their ADAM system setup.

     

    Actually MilliV might be able to better answer your questions.


  2. Hi.

    As a newcomer to the ADAM, I was wondering what the current state of modern storage on the ADAM was. The last post here dates from 2012, and most of the sites I have been to are either long dead or severely outdated...

    Frankly, the current ADAM landscape seems pretty barren, unless I'm missing something...

    The IDE CF Card setup was updated to a Dual CF Card setup with 100Mb of storage along with numerous other updates to the menu program. It is still available thru ADAMcon.

     

    ADAMcon also released the Virtual Disk Drive (aka ADAMnet SD Drive) in 2016 that uses disk images and therefore is compatible with all ADAM software.

     

    The latest addition to the lineup of ADAM modern storage devices is the ADAMnet Drive Emulator (ADE) by Sean Myers and built by John Lundy. You can find all the info on this one in a thread on here as well as the Coleco ADAM Facebook page.

     

    So all our modern storage needs have been met and are available for purchase.


  3. Once again thank you for the advice... but for this instance I'm sorry to say I'm not a social media fan.

    Neither am I, but I bit the bullet in this instance and having a former Coleco employee who was a big contributor to the development of the ADAM actively posting is all the initiative that one should need.

  4. I've been trying to reverse engineer the board in the piccies. Sorry I can't remember what thread I found it on but it appealed to me as the design seems to potentially support stupid amounts of RAM - about 2mb? But a conjunction of 'missing' info and running out of brain has left me a bit stuck.

    The Memory Expander pictured was made for and distributed thru E&T Software (Ed Jenkins). It uses 256K SIPP Memory Modules and can be upgraded in increments of 256K all the way up to 1Mb. I tested out quite a number of these that we sold thru NIAD, but they were always on a 256K populated board. I don't have much else to offer on this M.E.

     

    Attached are full schematics, silk screen, etc., etc. for the Micro innovations lineup of Memory Expander.

     

    Attached are pics of other Memory Expanders made for the ADAM... all install in Slot #3.

     

    Hopefully the Micro Innovations tech files will provide the necessary info you need for the memory addressing.

  5. Hello All,

     

    This may be a stupid question but I just recently got my Coleco Adam and I am loving it but I have looked high and low and cannot locate a real floppy drive or the old SD emulator option. I am hearing about this new project but this might be just beyond my skills to put together is any one Interested in putting together of these things for me and shipping it to me , I would be happy to pay a very reasonable price for it. If not no worries and I will watch the project with interest to see if anything goes into production.

     

    Thanks again in advance.

    Join the Coleco ADAM Facebook page and send a PM to John Lundy as he has made a couple runs already and looks like he has supplies to build another 15-20.


  6. Indeed, it would have been nice if the 3 internal expansion slots could or would have been identical/standardized and expansion cards could be installed in whichever one the user preferred. There must be a reason for the way Coleco designed them, but someone with the hardware knowledge such as Rich Drushel (Dr. D) or Doug Slopsema would be the ones to ask.

     

    The center expansion slot (#2 as we always referred to it) is used for Parallel Interfaces which can also supply the Memory Addressor function needed for 256K and larger Memory Expanders. Some of these Parallel Interfaces also supply a Boot Prom socket for instant loading of the program on the prom such as the IDE CF driver or SmartBASIC. Micro Innovations also made Multi-Purpose Interface cards (MIB2 and MIB3) that installed in this slot that supplied everything just listed as well a 2 Serial Ports.


  7. @tNIAD:

    :-) Thanks for the feedback. Yes, I think you're right. It's just I don't like having things dangling out of my machines, hence my reluctance to use the side port...

    ...but I guess that's an excuse to design a case too!

    I have to admit I upgraded my ADAM with an extra 64k by piggy-backing RAMs over the originals. Even more memory would be nice, especially if that proves useful for CP/M or TDOS. I must see if I can find a schematic for that too, if I can find one.

    I hear you. I prefer to keep everything internal as well, but when you gotta go outside the box.....

     

    There is no way to piggyback anymore RAM onto the motherboard as you did with the first 64K expansion. I am pretty sure that the ADAM can handle an additional 128K of expansion RAM without the need for a memory addressor, but once you go to 192K and larger, a memory addressor is needed.

     

    Might I ask a question? This card is a shameless clone of the MI_2SERB1 card as it's design suited my needs and as I suck at coding I didn't want to get in to trying to write my own drivers - especially as I'm really new to the ADAM...

    ...as mentioned above I'm not at all sure I did a functional job of reverse-engineering the GAL for that card. I don't suppose you know if there's a place where I can download the origial .JED file for use in my own GAL?

    If that's not possible / not on I quite understand. I can always keep my fingers crossed that my version actually works... of as a last resort do it in TTL.

    You will have to ask Bob Slopsema (adamcon) or his son, Doug. I know they looked into cracking the GAL for years with no luck.


  8. How is this new SD drive better than the one I bought a couple years ago? What are the new features?

    The ADE is better in numerous ways...

     

    - some VDD owners had issues with loading specific programs where communication with the Adam would be lost for some reason. No issues with the ADE.

    - up to 4 disk drives emulated at same time however the software program has to be configured to access all 4 so 2 is the norm.

    - access to 300 image files in the root versus the VDD's 100.

    - compatible with DDP image files as well as DSK image files

    - large disk image support

    - selectable image files thru an actual Adam menu program as well as thru the ADE unit

    - upgradeable thru USB port when new revisions are released

    - professionally assembled by John Lundy.

    - etc., etc., etc.

     

    There are more that you can view on Sean's GitHub website linked at the beginning of this thread as well as John Lundy's posts on the Coleco Adam Facebook page.

  9. This looks pretty great!

     

    Can anyone comment on the differences between this and the MicroFox CF flash interface (which I currently have)? A big one is obviously SD -vs- CF which are becoming harder to find. Just wondering what some of the functional differences/improvements are.

    The MicroFox IDE CF Package is a Hard Drive setup for the ADAM where you have to setup the actual ADAM program on partitions, the operating system (EOS) has to be patched to recognize it and there are numerous EOS programs that are not compatible with it such as the Super Games. On the T-DOS side, it really shines!

     

    The MicroFox VDD and Sean Myers' ADE are disk drive emulators that use any and all disk images of ADAM software. Everything is compatible with these SD Card drives on the EOS or CP/M / T-DOS side. Think of these SD drives as owning an actual ADAM Disk Drive and mounting and unmounting disk images is like inserting and removing actual diskettes.

     

    Good news is that it's great to have both the IDE CF package and the VDD or ADE SD drive and you can use them in conjunction with one another. The SD drive emulators are the better choice for most and Sean Myers' ADE is the one to go with now.


  10.  

    I know someone who had a Adam Colecovision they wanted to get rid of, I can check if they still have it if you like. Are the combo units desirable at all?

    The Stand Alone (with CV built-in) is more desirable because of the smaller form factor and Composite Video output option, but any confirmed working Adam is desirable and will find a buyer.
