The VT100 Terminal Kit by Peter Hizalev on Tindie includes the PCB and parts to build ASCII terminal that uses conventional PS/2 keyboard and VGA screen
This is VT-100 and XTerm compatible video terminal implemented on the PIC32 microcontroller. It has a serial interface with TTL or RS-232 signal levels, input from a standard PS/2 keyboard, and output to a VGA monitor. There is also a USB interface that supports serial over USB and acts as a USB-to-serial converter.
- Full compatibility with VT-100 and XTerm tested with vttest;
- All new SETUP utility available on Ctrl+Alt+Del;
- Configurable UTF-8, ISO 8859 and IBM PC 437 support;
- Configurable VT-220 and PC/Sun keyboards compatibility;
- Regular, bold, underlined and strike-through Terminus Unicode fonts;
- Blinking and inverted visual attributes;
- Configurable ANSI color-to-monochrome transformation;
- Support for historic DEC graphic characters;
- VGA output follows strict 25MHz pixel clock to get standard 640×480 resolution at 60Hz refresh rate;
- 8×16 characters and 24 or 30 lines screen buffers configurable in SETUP utility;
- Full range of baud rates from 110 up to 921,600;
- Scroll-lock and XON/XOFF flow control;
- PS/2 keyboard detection at startup;
- Dedicated timer pin for pixel data SPI framing instead of using VSYNC;
- Monochrome color is selectable with jumpers instead of solder bridges;
- Only US and UK keyboard layouts are supported (new layouts are easy to add–just let me know);
- Composite PAL/NTSC output is not supported;
- Serial communication speed is not configurable with jumpers, the only available configuration is with SETUP utility;
- Streamlined 4″x1.5″ board with VGA, PS/2 and USB ports on one side;
- Firmware source code and KiCad designs are open source. Contributions are welcome!
