    Default SukkoPera's C16/+4 Accessories: RAM Expansions, Carts & Joystick Adapters

    Since my first computer was a Commodore 16, I really had to design some hardware for it .

    For each item you can either buy the PCB alone, or the PCB plus a kit with all the components you will need to build the accessory. Either way, you will have to DIY, I will not be selling pre-built devices.

    Note that some items require the soldering of some SMD components in the 0805 package. For those who are not comfortable with that, I am offering to pre-solder them for free. If you require this service, please specify it in your order.

    OpenC16RamExpansion
    OpenC16RamExpansion is an Open Hardware 64 Kb RAM Expansion board for the Commodore 16.

    I guess this is a much desired item, but unfortunately AT THE MOMENT THIS EXPANSION DOES NOT WORK ON EVERY C16. At least, not out-of-the-box, there are workarounds but they will all require internal modifications to your computer, which are either not reversible or not easy to perform. This is not due to a fault in my project, but rather to internal shortcomings of the original C-16 design. Feel free to give suggestions on the project page on github if you want. So BUY AT YOUR OWN RISK!

    Note that these kits are not suitable for the faint-hearted, since they require soldering some surface-mount components (0805 package).

    Kit contains:
    • 4x100nF 0805 Capacitor
    • 2x16-pin Socket
    • 2x74LS257 IC (or 157, they are interchangeable)
    • 2x18-pin Socket
    • 2x4464-type 64Kx4 RAM IC


    Prices:
    • PCB: 3.00€
    • Kit: +8.00€


    OpenC16Cart
    OpenC16Cart is an Open Hardware 8/16/32 KB Cartridge for the Commodore 16, Plus/4 and the rest of the Commodore 264 family. For 32 KB images you will need to use two (E)EPROMs.

    This kit requires the soldering of two 0805 SMD resistors.

    Kit contains:
    • 2x100nF 0805 Capacitor
    • 12x3-pin Header Strip
    • 10xJumper Cap
    • 2x28-pin Socket


    Prices:
    • PCB: 3,00€
    • Kit: +5.00€
    • With Machined-Pin Socket: +1.00€ each
    • WinBond W27C512 EEPROM: +4.00€ each


    OpenRomSwitcher
    OpenRomSwitcher is an Open Hardware adapter PCB that allows the use of a 27xxx EPROM in place of a smaller (E)PROM. This is useful, for instance, for replacing the KERNAL and other ROMs in Commodore 16 home computers. It supports up to 8 different ROM images that can be selected through switches.

    This kit requires the soldering of three 0805 SMD resistors.

    Kit contains:
    • 3x10K 0805 Resistor
    • 3x0 0805 Resistor
    • 2x14-pin Header Strip
    • 1x28-pin Socket


    Prices:
    • PCB: 3.00€
    • Kit: +2,00€
    • With Machined-Pin Socket: +1,00€
    • WinBond W27C512 EEPROM: +4,00€
    • 1xSPDT switch: +0,50€
    • 4-core wire (30 cm/1 ft): +0,50€


    OpenC16JoyAdapter
    OpenC16JoyAdapter is an Open Hardware Adapter that allows using a Commodore 64/Amiga joystick on a C-16, Plus/4 and the rest of the Commodore 264 family.

    Kit contains:
    • 1xDB9 Male Connector
    • 2x2-pin Header Strip
    • 1x8-pin 90-degree Header Strip
    • 2xJumper Cap
    • 1x5x10k Resistor Array
    • 1x100nF Ceramic Capacitor
    • 1x74LS244 IC
    • 1x5x100R Independent Resistor Array


    Prices:
    • PCB: 3.00€
    • Kit: +5.00€
    • 8-pin Mini-DIN male connector: +2.00€


    Note that to complete this adapter you will need to make a 8-wire cable cable thst goes from the 8-pin header to the Mini-DIN connector. Mini-DIN connectors are not included in the kit and sold separately, and they are quite tricky to solder. On the other end, you can solder the cable directly to the board, if you prefer.

    Payment methods accepted: PayPal Family & Friends (or add commissions), Bank Transfer, Satispay (for Italian buyers)

    Items will ship worldwide from Italy. All shipments will be trackable and at cost. As a rule of thumb, shipping for up to two-three kits (total weight up to 100 grams) should be 4,30€ to Europe, 5,20€ to the US and 7,10€ to Australia. Add 6€ for tracked & signed for. Ask for exact quote.

    Items are also on sale elsewhere.

    Please note that I designed all of these boards primarily for my own use. I am open to suggestions and (constructive) criticism. All of my projects are Open Hardware, feel free to check out the KiCad design files on GitHub.

    There is more to come, but this is it for the moment. Feel free to ask any questions.
