Several attempts to write open-source emulators for various Lisp Machines have been made: CADR Emulation,<ref>{{cite web|url= http://www.unlambda.com/cadr/ |title=CADR Emulation |publisher=Unlambda |access-date= 12 November 2011}}</ref> Symbolics L Lisp Machine Emulation,<ref>{{cite web|url=http://www.unlambda.com/l-machine/ |title= Symbolics L Lisp Machine Emulation |publisher= Unlambda |date= 28 May 2004 |access-date= 12 November 2011}}</ref> the E3 Project (TI Explorer II Emulation),<ref>{{cite web|url= http://www.unlambda.com/lisp/e3.page |title=The E3 Project, TI Explorer II emulation |publisher= Unlambda |access-date= 12 November 2011}}</ref> Meroko (TI Explorer I),<ref>{{cite web|url= http://www.unlambda.com/lisp/meroko.page |title= Meroko Emulator (TI Explorer I) |publisher= Unlambda |access-date= 12 November 2011}}</ref> and Nevermore (TI Explorer I).<ref>{{cite web|url= http://www.unlambda.com/lisp/nevermore.page |title=Nevermore Emulator (TI Explorer I) |publisher= Unlambda |access-date= 12 November 2011}}</ref> On 3 October 2005, the MIT released the CADR Lisp Machine source code as open source.<ref>{{cite web|url= http://www.heeltoe.com/retro/mit/mit_cadr_lmss.html |title= MIT CADR Lisp Machine Source code |publisher=Heeltoe |access-date=12 November 2011}}</ref>

In September 2014, Alexander Burger, developer of [[PicoLisp]], announced PilMCU, an implementation of PicoLisp in hardware.<ref>{{cite web|url=http://www.mail-archive.com/picolisp@software-lab.de/msg04823.html|title=Announce: PicoLisp in Hardware (PilMCU)}}</ref>
