EASY CNC

I have listed an item for sale on Ebay for a friend and now I am
getting a bunch of questions and I don't know crap about it.

The item is an Omega Easy CNC (Ebay #1605810207) which is designed to
replace the tape reader or other memory on old NC, CNC machines.
Omega calls it a "memory expansion".

Most guys want to know what the memory capacity is. I think it is the
same as the PC from which you run the software, as the device has a
"loop" mode which supposedly feeds data 10K at a time.

Does anyone have any experience with this thing or know any more than
I do about it? The manual is not very good. Is Omega still in
buisiness?

What does DNC stand for anyway?

Thanks
