    Default Preorder: New Amiga 4000T (Tower) complete PCB sets

    I'm pleased to announce the reproduction of Amiga 4000 T PCBs. The design is complete and in production right now. Expected to start shipping in about 3 weeks, after production and prototyping of the boards.

    These are 6 layer boards identical in functionality to the A4000T Rev 4 motherboard PCBs. I will provide full BOM for the buyers in Excel sheet with component values and locations. But please understand that this sale is for the PCB set and component list, I will not provide support for building. 50 sets will be produced in original green color, HASL finish (silver colored NOT gold), as close to the original PCBs as possible. I don't plan to have further batches at the moment, will decide after the first batch (if there is enough interest). So I advise to get your board while you can Also important to note that this is NOT a bedroom/hobby/home made design. This has been done by a pro PCB design firm, and they've been in the business for decades. So the design, layout and routing is properly tested against PCB manufacturing standards and design verification rules, following industry practices, such as considering heat, signal propagation, noise and EMI, and correct ground and voltage layers. This is as close as you can get to actually owning an original A4000T motherboard PCB in 2019.

    The boards will be sold as sets, one set includes 1 of each: motherboard, video module, disk module and port module PCBs.
    Price per PCB set will be: $165 (150€) plus shipping + PP fees (4.5%) or bank transfer (no fees). PP payment will be goods payment in USD or EUR, and will only ship to your registered PP address. (shipping registered will be: $19 (17€) anywhere in the world). If you can, please choose bank transfer, it helps as it's easier for me to buy parts than with PayPal funds. For orders of more than 1 board, I will only accept bank transfers (IBAN or wire transfer in EU:EUR, USA:USD or GB:GBP to an account local to you).

    This thread is a pre-order for the boards to register interest.

    Please declare interest on this thread, AND send me a personal message with:

    1. how many sets you'd like
    2. payment type you want to use (PP/bank transfer).
    3. Your email address (if PP chosen then your PP email address)

    If you only write "Interested" on the thread nothing will happen until you send me a PM.


    Please monitor this thread as I'll be posting updates only here on status (prototyping start/finish, start payments, shipping etc.) When shipping starts I'll send out payment requests via email, and you'll have 3 days to send your payment, else I'll move down the queue. Also collecting interest from outside Amibay.

    Testing complete, everything is working. Tested all functionality, RTC, KB, mouse, ports, Zorro, video and PC slots as well. SCSI was only tested with an internal drive copying between CF IDE and a SCSI HDD for hours. Will work on the BOM and a few build tips. Will start sending out payment requests probably tomorrow. Payment deadline (from request) has been extended to 3 days.

    The PCBs have been designed by a professional PCB design firm and I own this particular design. The original authors are C= engineers of course

    You are not going to open this like the one I was working on? Great work, just sad to see it closed off with all the work being done to bring boards to everyone in the open communities. Plans to do so after the investment is paid back maybe? In any case I am interested in one set.

    How about creating a 3000T MB next?

    Maybe, but likely not. Others already are working in the A3000 space..

    Interesting to see and potentially interested.
    As you write, these PCBs have not gone through testing until now.
    What happens to all the orders should they have a fundamental flaw?
    Or will you first confirm them to work and the deal be void otherwise?

    In the latter case, please put me on the list

    Thanks in advance.
