Commander X16

Hello everyone! If you placed a pre-order for the Commander X16, we have an update! I know we said Feb 29th, but we are excited to announce that 150+ Commander X16 machines have arrived from manufacturing, and we are testing them now. We are working out a few last-minute details, but we expect to st...

If you do a digitalwrite to an input pin, it will activate the pullup resistor as well.  I had done that in my code originally, but I have proper pullup resistors on the rev 3 board as I recall, so I commented these out.

Yes, this is really just a quick and dirty bit of code I setup to get the power button working and make sure I could send data to it from the system.  This works, (except for the reboot command for some odd reason).  I never really took it any further.  <br /> <br /> Sorry I've been away for so lon...

The ATTINY861 is just like any other IC in the series.  I switched from the ATTINY84 mostly because it had the leg count I want. <span><span class="ipsEmoji">?</span>  I'm using the ATTINY (arduino) core with the small bootloader.  I have a really old original STK500 I'm using to program it, althou...

Hello everyone, <br /> <br />   I wanted to discuss an issue we have been struggling with, and that is PS/2 keyboard and mouse support.  This is probably not a secret to anyone watching the videos on the X16 as most of the time we are running at 4MHz or 2MHz.  This is completely due to PS/2 timing ...

Yes, that's how it's setup.  I also have a seperate 2-pin header for NMI.  The way I have the code in the microcontroller at the moment uses the reset pins on the header for both reset & NMI.  Short push for NMI & long for reset.  It works great, but takes a little getting used too, but I f...

Hello Everyone!   I received the parts for the third Prototype on Tuesday evening and spent a good chunk of that night and a bit of yesterday morning getting it worked out.  I had to get my code moved over to the ATTiny861 before the board would even power on.    This turned out to be pretty easy n...

While this is true, the reality is it's not working correctly.  I'm not 100% sure why, but the VERA is not initializing correctly with the current kernal.  Michael Steil is not a fan of the 816, so I'm guessing it won't be high on his priority list. ?

The bus pins may be a little misleading as some of them have the 65C816 names labeled.  I am debating on exactly how to label the board, or whether or not I should at all.  Even though the system is designed to be a 65C02 based machine, I designed it such that a 65C816 will work electrically in the...

Hey Everyone,    Sorry for the delay on an update.  It's been a hectic year once again and there never seem to be enough hours in the day.  I'm not a huge FB fan either,  but the reality is with our business, it's pretty key I keep on top of FB & the even more dreaded Twitter. <span><span class...
