 The '''VAXstation 100''' was a programmable [[graphics]] [[terminal]] manufactured by [[Digital Equipment Corporation|DEC]]. It had a [[bit-mapped display]], and could accept, for presentation to the user, text, diagrams or images (when running its usual on-board program, in its [[microprocessor]]).
-It consists of a separate chassis containing a 'display processor module', which is attached remotely to a 'bus window module' in the host computer, which connected it via [[fiber optic]] cables. The [[VR100 Monochrome Monitor|VR100]] [[display]] (a [[cathode ray tube|CRT]] capable of 1,088x864 [[pixel]]s [[resolution]]) was attached to the display processor module, along with a [[keyboard]] and [[mouse]]. (The chassis contained a separate [[power supply]].)

(The chassis contained a separate [[power supply]].)
 The display processor module used a [[Motorola MC68000]]; it had 128K bytes of [[main memory]], in addition to the 512K bytes of memory for the bit-mapped display (only 1/4 of that actually drove the display; the rest could be used to hold data such as [[font]]s). [[Bootstrap]] and [[diagnostic]] code was contained in [[PROM]]s; operating [[object code]] was downloaded over the fiber link once the VAXstation 100 had powered on. A 'Bit Blit Accelerator module' was attached to the display processor module; it used a separate [[bus]] to get to the screen memory. The BBA off-loaded some laborious low-level tasks (such a copying an area of the display to somewhere else, e.g. in moving a [[window]]) from the microprocessor, and performed them as quickly as possible.

	The VAXstation 100 is of some historical note due to its role in the development of the [[X Window System]]. Babara Liskov's [[CLU]] group had acquired a number of VAXstation 100 terminals and needed a [[window]]ing system running on [[BSD\|Berkeley Unix]]. Initially the [[W window system]] was used, but Bob Scheifler largely re-wrote it to become X.
