DMD 5620 Emulator for the Macintosh
The AT&T / Teletype DMD 5620 terminal was a portrait display, programmable windowing terminal produced in 1984. It came out of earlier research pioneered by Rob Pike and Bart Locanthi Jr., of AT&T Bell Labs.
Several iterations of terminals based on Pike and Locanthi's work were produced. The prototypes and early models were based around a Motorola 68000 CPU, and are better known as jerq or Blit terminals. The commercialized version produced jointly by the Teletype Corporation and AT&T in 1984 was called the DMD 5620, and used a Western Electric WE32100 CPU.
The goal of this project is to provide a highly accurate emulation of the DMD 5620 terminal.
- Added a new visual effect: You can optionally enable simulation of phosphor permanence on the screen. This makes the terminal much more realistic looking, at the expense of using more CPU to render the images.
- Fixed a bug that caused the app to crash when custom colors were set using non-RGB colorspace.
- Added clipboard paste functionality, accessible from the "Edit" menu, or from the keyboard shortcut Command-V.
- Fixed a bug that prevented terminal settings from being saved on quit.
- Added a "Reset" menu item.
- Upgraded to
dmd_core0.6.3 to fix video RAM and DUART bugs.
- Fixed a timing bug in downloading programs to the terminal
32ldon 3B2 hosts.
