The '''LINC-8''' was a computer produced by [[DEC]] for use in laboratory settings; it included both a [[PDP-8]] and a [[LINC]] computer, which shared access to the PDP-8's memory (the LINC acted as a DMA peripheral to the PDP-8, using the PDP-8 data break mechanism). A combined console allowed control of both [[CPU]]s.

Like the LINC, it included a video display (512x512 pixels), analog inputs, and [[LINC tape]] drives (all attached to the LINC); it could also include any of the standard PDP-8 peripherals (attached to the PDP-8).

Special interrupt-drive code ('PROGOFOP' - 'program of operation') in the PDP-8 allowed code running in the LINC access to PDP-8 resources; the PDP-8 likewise had access to the resources of the LINC (e.g. the display). When the PDP-8 was in control, the LINC was halted until the PDP-8 wanted something done, whereupon an interrupt started the LINC running, to perform the desired action.

		+	Like its PDP-8, the LINC of the LINC-8 was also constructed of discrete [[transistor]] [[FLIP CHIP]]s, mostly R- and S-series, in [[DEC card form factor\|standard-length single-height]] (width) format, with a few dual-height.

	It was later replaced as a product for DEC by the [[PDP-12]], which had the same functionality in a more integrated form.		It was later replaced as a product for DEC by the [[PDP-12]], which had the same functionality in a more integrated form.
