I just bought a old CNC machine from s shop that was closing down. Here's what I know.

It's a series 1 dovetail style machine. The serial # is CNC 1555. It has a J head serial# J2074250

The computer portion has an assembly# A025275 & a serial# 1614

I was hoping to find out what it is. I have not wired it up yet and don't even know for sure if it works.

How old is it? What is it (it kind of looks like a BOSS 6, but I don't see the word BOSS on it anywhere.

THANKS!!! in advance.

Would it be possible to get some photos of your new Toy? Im no expert but I know that will help. Especially if someone has the same one and knows exactly what it is.
I may be no expert but I do want to make goo goo eyes at it! Hey I can dream of my own one day! Take a look and scroll to the bottom.

Here are some pictures of the new arrival.

I wired it up today and fired it up. No motion on X axes, but I found some other posts about power transistors blowing and I was able to fix it. Ain't the internet great! Based on the low serial number I'm thinking Boss 3? Definitely not a Boss 6 as the stepper motor is 1-1 ratio. Now I just need to figure out how to program this thing. No documentation of course.

One step closer. I have a XDI board in the computer. According to a post I saw from Darek that means it's either a Boss 4 or Boss 5. Anybody know how to tell a boss 4 from a 5?

If the LSI has 4 large IC, it is a BOSS 4.
5 main IC on the LSI and you may have a BOSS 5.
The BOSS version is actually determined by the ERS board.
What part number is stamped on it?

LSI board has 5 Large chips on it upper left corner and the ERS part# is A027990

Consider it confirmed.
BOSS 5 with RS232.

Awesome, Thanks everyone! Lots of great info on this site!

Anyone know the years of production for Boss 5's? Just to get a idea of it's age.
