Dear Laura:
This is a DOS program and it seems to run OK out of my Windows 98 DOS prompt. I have it in a directory called C:\Brain. The "slink12r.exe" and the graphics driver "egavga.bgi" and everything else should be in that directory. The run format is "slink12r log001.dat".
Doug found the graphics driver on the internet. He seems to be the guru that could help you.
Andreas got it working OK today using the driver on my website.

Dear Jim,
I just tried running your slink12r program on my Win98 box, but have
not been able to get past the driver problem. I copied the driver
file to (1) the directory where slink12r is located (2) the C:
\Windows\System directory and (3) the C:\Windows\System\Drivers
directory, and I also tried rebooting. Can anyone give me more advice
on this?
I would prefer to get schematics in gif or jpeg. Thank you for
sharing!
Laura

believe I was able to see 0-200 Hz. To my disappointment, I saw no
data above 50 Hz (with my electrode placement) so I reduced the
sampling rate and went to 4 channels (a9.asm) instead. At that time,
working with a 386 computer, time was a "real" problem.
