Date of introduction:  1966 (during or before March).
Date of withdrawal:    1969
Total production run:  142.
Price: $38,500

Technology:  DEC Flip Chip modules, as in the PDP-8, with a LINC CPU
	partially reimplemented in Flip Chips and partially emulated
	with PDP-8 instructions.  (The original LINC was built from
	the same System Modules used in the PDP-5.)

Compatability:  The PDP-8 part of the machine was identical to the PDP-8.

Reason for withdrawal:  The PDP-12 accomplished the same goals at a lower
	cost.

Standard configuration:  The combined PDP-8/LINC CPU, plus 4K of memory
	was central to the system.  The set of peripherals bundled with
	the machine was impressive:

	-- An ASR 33 Teletype modified for the LINC character set.
	-- Two LINCtape drives.
	-- 8 analog to digital converter channels with knob inputs.
	-- Another 8 ADC channels with jack inputs.
	-- 6 programmable relay outputs, good up to 60 Hz.
	-- 1 Tektronix 560 oscilliscope, somewhat modified.

	The X and Y axis control for the scope came from DACs attached
	to the LINC's AC and MB registers, respectively.

Expandability:

	In addition to standard PDP-8 peripherals, up to 3 additional
	pairs of LINCtape drives could be added, for a total of 8 drives.
	The design of the type 555 dual DECtape transport was based on
	that of the LINCtape drive.

	Up to 2 additional ranks of 8 ADC channels could be added.

	Remote oscilliscope could be added.

Survival:  A few LINC-8 systems are in operable condition today.
