Re: I am working on a GS accelerator, can you help?

[The Name <Theemail@addr.ess>]

Someone please post the contact information for the person who started this
thread  (The orig post doesn't show up on my server)

I'll help in any way I can to help you get information for this project.  My
uncle is taking a look at a TWGS card of mine.  He is an electronics engineer.
I asked him to look at it and tell me if there is anything that can be done to
speed it up faster.

Maybe the original poster should contact me, and I'll put them in contact with
my uncle.
