Re: [CAD_CAM_EDM_DRO] re:Compumotor Parts Update

Hello,


First I feel as though I should apologize to everybody for wasting their
time with my questions. I am not sure how to address the situation so
everybody benefits from my interest in these parts I inherited from my
uncle. He left all his "shop stuff" to me since I restore cars. I have been
doing my best to try and figure out what the heck it all is and I must tell
you it's been nothing short of a real pain in my...

I have sold some of the things that I inherited on Ebay ( you've noticed the
word "ebay" in my links I'm sure ) and I suspect some of you feel as though
I am using this group as a means for finding out what all this crap is so I
can sell it. Those of you who do are certainly mistaken. My purpose here
Ballendo is to learn about this stuff and perhaps experience the joy's of
it's therapeutic value like my uncle did for years. Perhaps maybe I should
just email you outside the group; except I know there is so much more
knowledge within all the people in it.

To answer a few more of your questions, I can tell you some of the boards
are still being made today and others are not. I have been having trouble
identifying the boards that aren't clearly marked "Compumotor" so I have no
answer about them except that they are old. That's perfectly acceptable for
me.

Here's the part where I truly waste your time. I'm not sure what I want to
build yet. I guess once I feel I have enough of a grasp on what my
possibilities are I'll get more seriuos about it. I'm only starting out
here and my first goal is to see what I have inherited. Maybe I should
participate in the group at a later date when I have more knowledge about
this stuff; like for instance, what is Mariss?
