Display peripherals for PDP-10

Do any of these still exist? "346/ 340B PRECISION' INCREMENTAL CRT DIS- PLAY: plots points, lines, vectors, and char- acters on a 9 3/8 in. square raster of 1,024 points along each axis. 1 1/2 us is required per point in vector, increment, and character modes. Random point plotting rate of 35/is. A 370 high-speed Light Pen is included. 342B CHARACTER GENERATOR for 346/ 340B 348/VR30 PRECISION POINT PLOTTING DISPLAY: operates at a maximum plotting rate of 20 KC or one' point every 50 ,ts on a 9% in. x 9% in. display area. Number of addressable points along each axis is 1024. A 370 high-speed Light Pen is included. ' VP10 POINT PLOTIING DISPLAY CONTROL: operates at either of two maximum' plotting rates. Low rateis 10 KC (one point every 100 ns). High rate is 50 KC (one point every 20 Ms). Number of addressable points along each axis is 1024. Control interfaces to. a cus- tomer supplied oscilloscope (Tektronix Type RM503 or equivalent) or to a CRT display. 370 HIGH SPEED LIGHT PEN: for use with VPl0." I'd never heard of there being graphics display peripherals. Looks like these are storage tube technology based, even though the description says "raster". I think here they just mean the addressable range of points on the tube. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
