any information would be nice

Old Snap On. I'll bet that was a pretty penny back when it was new. My dad has a TON of Snap On tools from when he was a mechanic. Looks like its his dwell meter, timing light(I see the jack for it on here) and the...crap i cant remember his 3rd meter/gauge that looks like these. Have to dig it out.

im missing the timing light

That sucks. That stuff will work forever. All of my dad's equipment from 1979 when he finished trade school still works.

it turns on but im still trying to figure it out

probably a scope of some kind on there too.

The top screen looks like an oscilloscope. There are some leads that connect to the coil (a special one that clips on to the top of an HEI) and the scope shows the energy wave that happens in each cylinder. The pattern looks kind of like a heartbeat, and you can tell which cylinder is different from the rest.

I'm told that the older televisions make great oscilloscopes for cars with solid wires, lol!

Got any shots of the gauges? I'm thinking that's similar to one that I worked with back in high school Vo-Tech. If so, that machine should be able to tell you just about anything electrical that you want to know.

whats the attachment for the hei look like and could i possibly make one

The HEI attachment kind of covers the top of the distributor and gets the oscilloscope info via magnetic induction from the coil.

any pictures

The pulses of the cylinders in the scope can indicate a few things. If I remember correctly the amplitude (height) of the pulse can indicate a cylinder with lower compression, since the spark energy is different from a low to high cylinder pressure etc. I used one in the 60s, but I have CRS these days........
Any manuals with it ? I would bet that some info or copies of manuals could be found on the internet.

i havent been able to find anything i pulled it out of a barn that was falling down 3or 4 years ago havent seen one like it

There should be a data plate or tag with a model number on it on there someplace. If you find a model number, do a Google search for a manual for it. Some places have manuals that can be down loaded.

I want to say there's also a book out there that goes into detail on how to read, diagnose, & operate an automotive oscilloscope. Could be losing my memory though. I read a lot of books.
