VT-180

In 1982, Digital introduced an option board which turned a VT-100 terminal into a personal computer using the CP/M operating system. It was called the Digital's Personal Computing Option. Customer could purchase just the option board or could buy the complete terminal/computer package called the VT-180.

The VT-100 terminal was introduced by Digital in August 1978. It rapidly enjoyed great popularity and soon became the most widely imitated asynchronous terminal. Its control codes and escape sequences still form the basis of the xterm set and of the ANSI or IBM PC standards. VT100 compatibility is still provided by most terminal emulators. All terminals that came after the VT100 was able to emulate their ancestor, although they offered new features in addition to what the VT100 could do.

The VT-180, also called 'Robin', was thus basically a VT100 terminal with an extra board installed which includes a Z80 processor, 64 KB of RAM memory, a floppy disk controller and an extra serial port controller. The single sided floppy disk drives came in a dual case. The system supported up to four individual disk drives (two dual drive units).
