Tektronix 4051

 

Vector display

The 4051 is a 6800 based BASIC computer that was introduced in 1976. 

 

The price was $6995 and the base memory was 8kbyte. Instead of a regular CRT as a display it uses a DVST, Direct View Storage Tube so that the display itself keeps the drawn image by a special arrangement of electrode beams inside the tube. DVST was a technology that Tektronix has mastered for very long time in its range of analogue storage oscilloscopes and also made use for in their line of terminals and computers. The slot to the right is a tape drive for DC300 quarter inch tape cartridges.   Current value (2019) of a working 4051 system is about $2000 (recent eBay sales).
