  1. Great product 4 Star Review

    Posted by on 14th Oct 2017

    This is one of the best products for C64, a must have product.
    The reason for the 4 stars instead of 5 is simply that there is no manual for it.
    However a search in one of the popular C64 forums usually clear things like compatibility and how the switches should be set.
    All switches down for all power and io lines to be on will probably be the answer from your first search.
    Get one for yourself, mine is in use daily.

    Nice piece of tech. I'm using the xpander with the 1541 Ultimate II and Midi Interface simultaneously. No probs with 1541U2 drive emu, even REU stuff runs like a dream.

  4. Easy to flush POS. 1 Star Review

    Posted by on 26th Nov 2015

    The whole entire of a port expander is to allow you keep your carts plugged in and simply switch between then. In times gone by, DECENT port expanders such as the Aprospand etc did just this.

    Unfortunately, this POS does not. It has three major problems.

    Firstly, it only has 3 (supposedly)individually select-able ports. The third and forth are connected and cannot be separated, so if you have a two carts that do not play nice with each other (which most dont) then you can only use one in either slot 3 or 4, not both, making one slot a waste of plastic.

    Secondly, the card uses a heap of ridiculous dip switches to select, well, who knows. I assume it is to select individual address lines that are connected. Why? Dip switches are not designed for continual use and have a VERY VERY short lifespan. Also, why not just have a bloody switch like DECENT expanders? To select/unselect a slot with this POS you have to slip about a dozen dip switches?!?!?! Crazy.

    Thirdly, and this is by far the biggest issue I had. With all of those stupid dip switches, the card STILL does not properly isolate the slots!!!! For instance, if you have two carts that do not like each other, then chances are you will be unplugging/plugging carts in to make the system boot as the sip switches do not properly isolate each cart. Other expanders with a simple switch to switch a slot in and out do not have this problem (such as the mighty Aprospand).

    So what exactly is the use of a port expander that forces you to unplug/plug carts constantly anyway? Absolutely none.

    If you ever wonder why used (decent) port expanders from 30 years ago still fetch good prices on eBay, buy one of these X-pander POS's and you will soon find out.

    Avoid like a bad case of the crabs.

  5. Great on quality, short on documentation 4 Star Review

    Posted by on 8th Feb 2015

    The X-Pander 3 is a very well-built piece of kit. It provides more than ample support for all types of cartridges, and the included LEDs and DIP switches are great. My only complaint is that no documentation was included to highlight and explain the configuration capabilities that the X-Pander 3 offers. I have also not located any docs online.

  6. Xpander 3 Complete 5 Star Review

    Works perfect and easy.

    Can Combine carts on the C64 with no trouble.

    Perfect for combining the 1541 Ultimate and a SIDII cart !

  7. Well worth it 5 Star Review

    Posted by on 28th Apr 2014

    Works exactly as advertised. I have an Aprotek cart expander also and this one is definitely better. The easy throw switches are perfect for turning on and off particular ports. I use it with my 1541 Ultimate II and Easyflash 3 and couldn't be happier.

  8. Best Cartridge Port expander 5 Star Review

    Posted by on 3rd Apr 2014

    I have an Aprospand Cart Port Exp and this one blows it away. Easy to switch ports in and out on top of all the other dip switch settings. It is built very sturdy, which needs to be if changing carts all the time. Currently using it with my 1541 Ultimate II and EZFlash 3.

  9. Get One 5 Star Review

    Posted by on 4th Jan 2011

    Elegantly designed, the rear facing port is perfect for a 1750 REU. With the X-Pander 3 I can use my 64NIC with my REU, and by flipping down the easy to handle long throw DIP switches I can easily switch in my Final Cartridge III. Get one.

  10. Works Perfectly 5 Star Review

    Posted by on 27th Oct 2010

    I have one of these and it works like a champ! I loge the ability to swap the IO line, and the combination of a horizontal and vertical plug for the 3rd plug!
