Editing Blit (computer terminal) (section)

==Window systems==
Pike wrote two window systems for the Blit, ''mpx'' for [[Research Unix#Versions|8th Edition Unix]] and ''mux'' for 9th Edition, both sporting a minimalistic design. The design of these influenced the later [[Plan 9 from Bell Labs|Plan 9]] window systems [[8½ (Plan 9)|8½]] and [[Rio (windowing_system)|rio]]. When the Blit was commercialized as the DMD 5620, a variant of mpx called "layers" was added to [[UNIX System V#SVR3|SVR3]].<ref>{{cite web |title=AT&T 5620 (and Related Terminals) Frequently Asked Questions |author=Eric Smith |date=25 August 2005 |url=http://www.brouhaha.com/~eric/retrocomputing/att/5620/5620_faq.html}}</ref>
