* GT42 – VT11 vector graphics terminal using a PDP–11/10.<ref name="gt40/42" />
* GT44 – VT11 vector graphics terminal using a PDP–11/40.
* GT62 – VS60 vector graphics workstation using a PDP–11/34a and VT48 graphics processor.
* [[Heathkit H11|H11]] – [[Heathkit]] OEM version of the LSI-11/03.
* VT20 – Terminal with PDP–11/05 with direct mapped character display for text editing and typesetting (predecessor of the VT71).
* [[File:PDP-11-34 front panel.jpg|thumb|229x229px|PDP–11/34 front panel which was a replacement for toggle switches in earlier PDP–11 computers]]VT71 – Terminal with LSI-11/03 and Q-Bus backplane with direct mapped character display for text editing and typesetting.
* [[VT103]] – VT100 with backplane to host an LSI-11.
* VT173 – A high-end editing terminal containing an 11/03, which loaded its editing software over a serial connection to a host minicomputer. Used in various publishing environments, it was also offered with DECset, Digital's VAX/VMS 3.x native mode OEM version of the [[Datalogics]] Pager automated batch composition engine. When VT173 inventory was exhausted in 1985, Digital discontinued DECset and transferred its customer agreements to Datalogics. (HP now uses the name HP [[DECset]] for a software development toolset product.)[[File:DEC-MINC-23.jpg|thumb|MINC-23 laboratory computer|229x229px]]

* [[MINC-11]] – Laboratory system based on 11/03 or 11/23;<ref>{{cite web|url=http://www.binarydinosaurs.co.uk/Museum/Digital/minc/index.php |title=Digital MINC-11 |publisher=Binary Dinosaurs |access-date=2014-04-14}}</ref> when based on the 11/23, it was sold as a 'MINC-23', but many MINC-11 machines were field-upgraded with the 11/23 processor. Early versions of the MINC-specific software package would not run on the 11/23 processor because of subtle changes in the instruction set; MINC 1.2 is documented as compatible with the later processor.
* [[C.mmp]] – Multiprocessor system from [[Carnegie Mellon University]].
[[File:Unimation controller internals.jpg|thumb|This [[Unimation]] robot arm controller used DEC LSI-11 series hardware.|229x229px]]
* The [[Unimation]] robot arm controllers used Q-Bus LSI-11/73 systems with a DEC M8192 / KDJ11-A processor board and two DEC DLV11-J (M8043) async serial interface boards.
* SBC 11/21 (boardname KXT11) Falcon and Falcon Plus – single board computer on a Q-Bus card implementing the basic PDP–11 instruction set, based on T11 chipset containing 32&nbsp;KB static RAM, two ROM sockets, three serial lines, 20&nbsp;bit parallel I/O, three interval timers and a two-channel DMA controller. Up to 14&nbsp;Falcons could be placed into one Q-Bus system.
* KXJ11 Q-Bus card (M7616) with PDP–11 based peripheral processor and DMA controller. Based on a J11 CPU equipped with 512&nbsp;KB RAM, 64&nbsp;KB ROM and parallel and serial interfaces.
* HSC high end CI disk controllers used backplane mounted J11 and F11 processor cards to run the CHRONIC operating system.<ref name="ReferenceA">{{cite book|url=http://vaxhaven.com/images/b/ba/EK-HSCMN-IN-002.pdf|id=EK-HSCMN-IN-002|title=HSC Controller Installation Manual|at=p. 4-28|date=July 1991|publisher=Digital Equipment Corporation|access-date=2017-05-29|archive-date=2019-09-03|archive-url=https://web.archive.org/web/20190903150133/http://vaxhaven.com/images/b/ba/EK-HSCMN-IN-002.pdf|url-status=live}}</ref>
* VAX Console – The [[DEC Professional (computer)|DEC Professional Series]] PC-38N with a real-time interface (RTI) was used as the console for the [[VAX 8000|VAX 8500 and 8550]]. The RTI has two serial line units: one connects to the VAX environmental monitoring module (EMM) and the other is a spare that could be used for data transfer. The RTI also has a programmable peripheral interface (PPI) consisting of three 8-bit ports for transferring data, address, and control signals between console and the VAX console interface.<ref>{{cite book |author=<!--Staff writer(s); no by-line.--> |title=VAX 8500/8550 System Hardware User's Guide |publisher=Digital Equipment Corporation |pages=1–8 |date=1986 }}</ref>
* [[DEC T-11|T-11]] is a microprocessor that implements the PDP-11 instruction set architecture. It was developed for embedded systems and was the first single-chip microprocessor developed by DEC. It was sold on the open market.<ref>{{cite web |date=March 24, 1982 |title=T-11 Engineering Specification |url=http://www.bitsavers.org/pdf/dec/pdp11/t11/T11_Engineering_Specification_Rev_E_Mar82.pdf |access-date=May 15, 2023 |archive-date=March 8, 2023 |archive-url=https://web.archive.org/web/20230308003715/http://www.bitsavers.org/pdf/dec/pdp11/t11/T11_Engineering_Specification_Rev_E_Mar82.pdf |url-status=live }}</ref>
