We are working out a few last-minute details, but we expect to st...

PS/2 Direction for the Commander X16


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.

PS/2 Direction for the Commander X16

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...

PS/2 Direction for the Commander X16

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...

PS/2 Direction for the Commander X16

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 ...

Front panel connection

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...

Prototype #3 - Parts have arrived and the first one has been built!

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...

Bus Pinout on Proto #3


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. ?

Bus Pinout on Proto #3

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...

Prototype #3?

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...
