One of my previous blog posts that is about recreating Atari XL/XE floppy disks describes a SIO2USB interface inside my Atari 65XE. The advantage of it is that it includes a switch that lets you toggle between the USB connection and the SIO port. This way you can easily switch between a real and virtual floppy disk that can be mounted with AspeQt software and copy real floppy disks to disks images and the other way around.
In my previous blog, I have written a bit about the remake of the PCB board for Atari 800XL computer. Now I will describe the process of acquiring all the parts needed to build it.
There are a few simple assembly steps required to dress up your DE10-Nano board and transform it to a fully functional retro machine.
As a child I have owned an Atari 800XL. This 8-bit computer always had a special place in my heart. After almost 35 years I have decided to dive a bit deeper into the circuitry of this now called retro computer. What better way to start is to remake the PCB from scratch.
When you need to connect more then one USB device to your DE10-Nano FPGA board then you need to use a powered USB hub. It is possible to use normal hub, but it is way cooler to connect the one that is custom designed for the MiSTer project.
MiSTer project that is installed on the DE10-Nano board can only output video using the on-board HDMI connector. However if you want to get the real retro gaming experience then you can attach the MiSTer IO Board. Among other things, this add-on board let's you output 15KHz analog RGB video and audio signals that will let you connect to a CRT monitor. This blog post describes how to build such a board.
In order to connect your DE10-Nano board to VGA or other RGB output, you need an I/O Board. This PCB board and assembly instructions are available on the GitHub pages of the MiSTer project.
Getting FPGA cores of your favourite retro systems onto the DE10-Nano is very easy. You can run them in matter of minutes.
