* PDT-11/110
* PDT-11/130
* PDT-11/150

The PDT series were desktop systems marketed as "smart terminals". The /110 and /130 were housed in a [[VT100]] terminal enclosure. The /150 was housed in a table-top unit which included two 8-inch floppy drives, three asynchronous serial ports, one printer port, one modem port and one synchronous serial port and required an external terminal. All three employed the same chipset as used on the LSI-11/03 and LSI-11/2 in four "microm"s. There is an option which combines two of the microms into one dual carrier, freeing one socket for an EIS/FIS chip. The /150 in combination with a [[VT100#Variants|VT105]] terminal was also sold as [[MiniMINC]], a budget version of the [[MINC-11]].

* PRO-325
* PRO-350
* PRO-380

The [[DEC Professional (computer)|DEC Professional]] series are desktop PCs intended to compete with IBM's earlier [[Intel 8088|8088]] and [[Intel 80286|80286]] based personal computers. The models are equipped with 5{{frac|1|4}} inch floppy disk drives and hard disks, except the 325 which has no hard disk. The original operating system was P/OS, which was essentially [[RSX-11]]M+ with a menu system on top. As the design was intended to avoid software exchange with existing PDP–11 models, the poor market response was unsurprising. The [[RT-11]] operating system was eventually ported to the PRO series. A port of the [[RSTS/E]] operating system to the PRO series was also done internal to DEC, but it was not released. The PRO-325 and -350 units are based on the DCF-11 ("Fonz") chipset, the same as found in the 11/23, 11/23+ and 11/24. The PRO-380 is based on the DCJ-11 ("Jaws") chipset, the same as found in the 11/53,73,83 and others, though running only at 10&nbsp;MHz because of limitations in the support chipset.
