I know this has been discussed in the past but not with any real information. We have a VF3 year 1998, with 1mb memory. We currently DNC for large 3d programs. The price for adding the 16mb memory is quite high being around $1,400.00. I find this to be an overcharge in my opinion. Has anyone upgraded the memory on their own. If so can you provide instructions and where to locate the memory chip. Thanks
