retrocomputing (/ret'·roh·kəm·pyoo´ting/ n.)

Refers to emulations of way-behind-the-state-of-the-art hardware or software, or implementations of never-was-state-of-the-art; esp. if such implementations are elaborate practical jokes and/or parodies, written mostly for hack value, of more ‘serious’ designs. Perhaps the most widely distributed retrocomputing utility was the pnch 6 or bcd 6 program on V7 and other early Unix versions, which would accept up to 80 characters of text argument and display the corresponding pattern in punched card code. Other well-known retrocomputing hacks have included the programming language INTERCAL, a JCL-emulating shell for Unix, the card-punch-emulating editor named 029, and various elaborate PDP-11 hardware emulators and RT-11 OS emulators written just to keep an old, sourceless Zork binary running. A tasty selection of retrocomputing programs are made available at the Retrocomputing Museum, http://www.catb.org/retro/.
