[dba-Tech] Manually eject CD from a drive without a tray

Had a fellow call and ask if I could get his "new" computer past a password
for him that he didn't know. He bought this PC at an estate sale and didn't
know any passwords.
 
After a couple of questions I determined it was the bios password and so
that was a quick fix but since he had to drop it off I'd check it over for
him while I was at it.
 
Poor dude just bought a Compaq Presario with a Pentium (1), 32MB of RAM, 6GB
HD and WIndows 95. The things is built like a tank though and runs quite
well.
 
My problem is that it has a CD Drive without a tray and the bugger won't
cough up one of my CDs! It worked with other CDs before this one. Of course
with a tray system they have the little hole where you can manually open the
tray. But I have no idea how to manually eject this thing. Any Ideas?
