For a long time I have been looking for the JOLT. I already had it in my hands, but the owner sold his whole collection to someone else. If anyone has a JOLT to offer, please contact me through my website.

Hi to all that have commented. I am very sorry I missed some required responses. Please go to my website and you can send a contact message to me from there. Thanks for remembering the JOLT. It was a great little workhorse.

I still have the Jolt system I purchased in 1977. I have the CPU, 2k EPRom board, Power supply and all the original documentation. It used a machine language program blown into 1702A EPROMs It was used to control audio sources (reel to reel, carts stuido and network ) for a radio station. It was used very successfully for many years before the advent of the modern hard disc based play out systems.

Always reliable, it still functions (at least the last time I tried it about a year ago).

A truly great little computer!

In 2015 I had the chance to get hands on the JOLT. Unfortunately it was not for sale. I would love to get this early computer. Any offer welcome.

Microcomputer Associates was one of my first employers. I worked with Manny and Ray packing the kits and soldering the assembled boards. I was one of the first 5 employees - Ray, Manny, Frank, Darrel and myself.
I would love to get in touch with these guys again. Ray, Manny and Frank were my mentors.

If anyone has questions about the F-14 CADC, Jolt, Super Jolt or SYM early computers just let me know.

The JOLT was my first computer. It was a great little machine. I did a number of interesting projects in the physics lab, connecting it geiger tubes and the like for counting decays per unit time, etc.

Anyway, I still have it, as well is some of the literature. I could post some photos, if I could figure out how to do it. This form does not seem to allow it.
