⌨️Exploring different keyboard interfaces to send data to the computer.
🖥️Considering the use of an AVR microcontroller to process and output data.
🔌Connecting the computer to a laptop for serial input and output.
🔧Finding and using existing video and keyboard interfaces to simplify the project.
What is the purpose of the CRT monitor in a 6502 computer project?
—The CRT monitor is used to display the output of the 6502 computer, similar to how Steve Wozniak's Apple One used a CRT monitor.
What challenges did you face when trying to connect the computer to a CRT monitor?
—I had to understand how composite video and ntsc video worked and find a way to integrate it into my breadboard computer.
Did you consider using an LCD screen instead of a CRT monitor?
—Yes, I considered using an LCD screen but decided to go with a CRT monitor for its retro aesthetic.
How did you connect the computer to a laptop?
—I used a serial connection and connected the RX and TX signals of the computer to a USB serial adapter on my laptop.
Can I use your design for my own 6502 computer project?
—Yes, you can use the video and keyboard interfaces I used in your own project. I will provide links to the resources in the description.
00:00I finished my 6502 computer project and wanted to connect it to a CRT monitor.
00:10I researched how composite video and ntsc video worked to integrate them into my computer.
00:38I initially planned to use an AVR microcontroller to process and output data.
01:26I struggled with programming AVR chips and decided to focus on getting serial input working.
02:36I designed a PCB and soldered the components to create the video and keyboard interfaces.
06:32I tested the computer with a CRT monitor and verified that it worked.
08:39I connected the computer to a laptop using a USB serial adapter for input and output.
09:57I connected the LCD screen to the computer, allowing for optional use in the future.
