TLDR;

This product is a printed circuit board based on the original Geoff Graham design.

If you need the entire kit you can buy it here.

ATTENTION! Version 3.2 of the ASCII Terminal has following significant changes to the original Geoff's design:

• 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 640x480 resolution at 60Hz refresh rate;
• 8x16 characters and 24 or 30 lines screen buffers configurable in SETUP utility;
• Bell buzzer (can be turned off in the SETUP utility);
• Full range of baud rates from 110 up to 1,500,000;
• Scroll-lock and XON/XOFF flow control;
• PS/2 keyboard detection at startup;
• Monochrome color is selectable with jumpers instead of solder bridges;
• US, UK, DE, SE, FR and BE keyboard layouts are supported;
• 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!

Description

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.
