- Cobbling Prototyping - In the previous blog entry, I talked about old computers, how the user input and output evolved, and why I decided to build my own terminal. I wrote how I remembered the FabGL library , how it did SVGA, had an AnsiTerminal as example, and how Just4Fun made a serial terminal using that FabGL library . I then set out my goals and stretch goals, tools to be used, and just started. Ancient Dutch wisdom: "He who saves something, has something" The first thing I wanted to do was to cobble together prototype something that would resemble the LILYGO VGA32 board . When I work on prototype projects, I always try to see if I can make reusable components. From an old project, I had a board that combined a 5V power supply with an RS-232 level converter (MAX232). And from another (FPGA) project, I had a board that would take 5V from a USB and provide 5V and 3.3V supplies, PS2 keyboard and mouse ports, and R2-R networks connected to a VGA connector for VGA outp...
