TEK Vectors

TEK Vectors is about Tektronix 4050 series vector graphics microcomputers introduced in the 1970's targeting scientific, engineering, medical, CAD, and business graphics.  

The 4051 was introduced in 1975 with a Motorola 6800 CPU, 32KB of BASIC ROM, 32KB of RAM and a 12-inch 1024x780 vector display.  

The second generation 4052 was introduced in 1979 with a 16-bit custom bit-slice CPU with the same vector display but 64KB of RAM and about 8X faster BASIC program performance due to faster CPU clock rate and hardware floating point in the bit-slice CPU. 

The 4054 was introduced at the same time as the 4052 with the same bit-slice CPU and RAM but had 3X faster vector graphics performance and 4X the vector resolution at 4096x3072 on a 19-inch vector display!  The 4054 also had an Option 30 Dynamic Vector Graphics coprocessor that added the ability to display large numbers of vector objects on the display in refresh mode.

I have a 4052 and 4054A /w Color Dynamic Graphics & Option 30.
