Only three PDP-1 computers are still known to exist, and all three are in the collection of the [[Computer History Museum]] (CHM).  One is the prototype formerly used at MIT, and the other two are production PDP-1C machines.  One of the latter, serial number 55 (the last PDP-1 made) has been restored to working order, is on exhibit, and is demonstrated on two Saturdays every month. The demonstrations include:

* the game ''[[Spacewar (video game)|Spacewar!]]''
* graphics demonstrations such as Snowflake
* playing music

Software simulations of the PDP-1 exist in [[SIMH]] and [[MESS]], hardware recreation through [[FPGA]] exists for the [[MiSTer]] project as well, and binary image of paper tapes of the software exist in the bitsavers.org archives.<ref>{{Cite web |title=Index of /bits/DEC/pdp1/papertapeImages |url=http://bitsavers.org/bits/DEC/pdp1/papertapeImages |url-status=live |archive-url=https://web.archive.org/web/20220107215435/http://bitsavers.org/bits/DEC/pdp1/papertapeImages/ |archive-date=2022-01-07 |access-date=2022-03-16 |language=en |via=[[Computer History Museum#Software|Bitsavers]]}}</ref>
