The Jolt computer used the 6502 microprocessor and was somewhat advanced in 1975. This is before the Apple 1 or Apple ll and the same year as the Altair 8800 microcomputer. The Altair 8800 sold for $395 in kit from with no software and a very small memory. The Jolt came with a monitor debugger program called Demon and had an interface for the Teletype (RS232 20 MA current loop). The wired unit sold for $348 and kit $249.  Accessory cards were also available like the 4kb RAM memory card for $320. However the computer never became very popular.

Here  is a video I made with Ray Holt telling his Jolt story. I made this at the Vintage Computer Festival SE 4.0 in April 2016.

The Jolt microcomputer was released in 1975 by Microcomputer Associates. The company was founded by Ray Holt and Manny Lemas.  The company was later acquired by Synertek, a second source manufacturer of the 6502, and renamed Synertek Systems. Synertek went on to produce the popular SYM-1 microcomputer. Ray Holt did some early microprocessor development work for use in the F-14 Tomcat aircraft.  This work was classified and Ray's design work during the period 1968 to 1970 may have been the very first microprocessor chip set .

The Super Jolt computer is on display in our "Bugbook Historical Microcomputer Museum"  located in Floyd , Virginia. The computer card is setting on top of original box from Jolt. I don't remember just when or who I received the computer from & the box also has a SYM-1 in it. Microcomputer Associates/Synertek produced these computers - this was a nice addition to our collection with 2 new and never used microcomputers.
