This is a software simulation of the VT100 hardware. The original firmware ROM is built in and executed by an 8080 emulator. Other components include video display with character generator ROM, settings NVRAM, Intel 8251 USART, and a keyboard matrix scanner. The Advanced Video Option is not included.
To build this, you need to have the SDL2 and SDL2_image libraries installed.
The command line syntax is vt100 [-f] [-D] [-R test] program/device.
-fenters full screen. Toggle with F11.-Denters a PDP-10 style DDT for debugging the firmware.-R testruns a CP/M program; this is only for testing.-Cturns capslock into control.-Qdisables use of OpenGL.-Nfield rate.program/deviceis any command to run as a child process providing I/O, or a character device assumed to be a serial port.
F9 is the SET-UP key. See a VT100 User Guide for instructions. Control+F11 exits the simlator.
This simulator was inspired by Michael Gardi's 3D printed model, see his instructions and GitHub files.
This is my printing progress so far:
