Core logic for an AT&T / Teletype DMD 5620 terminal emulator
The AT&T / Teletype DMD 5620 terminal was a portrait display, programmable, windowing terminal produced in the early 1980s. It came out of research pioneered by Rob Pike and Bart Locanthi Jr., of AT&T Bell Labs.
This project implements the core logic needed to emulate a DMD 5620 terminal, including:
- WE32100 CPU
Note that there is no user interface: This is a back-end library only. It may be used as a component to build a fully-fledged emulator, however.
0.6.3: Bug fixes: Video Ram starting address was not being
updated correctly for video ram read; Implement
read_word for DUART (needed to run
0.6.2: Fix UART character delay timing.
0.6.1: Fix failing tets.
0.6.0: Breaking change. Refactor DMD a bit to rename the function
read_word, and added a
as well. Also refactored the CPU mnemonic lookup to be
more efficient using a lookup table instead of a HashMap.
Lastly, fixed a bug in the DUART that set the wrong
delay for one baud rate.
0.5.0: Non-breaking but major change.
dmd_core now presents a
C compatible API to make interacting with C and C++ code
easier, without needed to write a full stub library.
0.4.0: Breaking change. TX to the keyboard from the terminal is now supported, so that clients can use it to detect when a bell (^G) request has been sent.
0.3.1: Added exception handling for memory errors, and a
to free-run the CPU for a given number of steps.
0.3.0: Breaking change. Charater RX from RS-232 and keyboard are now
handled by internal queues, and no longer return
0.2.1: Initial release.
Two implementations of DMD 5620 emulator use this core library.
The Linux native GTK application
The Macintosh native Cocoa application

A Windows native application is in the works.
