Very popular video terminal by DEC, introduced 1975. The CRT displays 24 lines of 80 characters in both upper and lower case.
It uses a custom processor built from TTL parts to execute 1024 words of 8-bit wide microcode. The data path is 7 bits wide, as is the 2048-word RAM. The predecessor VT50 is almost identical, except there is only 512 words of microcode, 1024 words of RAM, the CRT display 12 lines, and text is upper case only.
A VT52-compatible terminal emulator was used in the Atari TOS operating system.
