We have, and unfortunately you are not alone.
There are still a handful of laptops w/ parallel ports - but they are few
and far between, and almost exclusively found on larger "high end" boxes
that target heavy computation etc.

Really your only option is to purchase an add-on parallel card that uses the
PCMCIA bus or PCIExpress. They can be had w/o costing too much.

A note - there are USB-based parallel "converters" - but these DO NOT WORK
for this kind of use, Windows etc still views it as a serial device.

Subject: [Eeglablist] Parallel port

Hello,
In our EEG system we`re sending TTL codes through the parallel port of the
display PC which are recorded in a separate EEG channel. These codes are
used in order to synchronize the EEG data with the stimuli. Since this is a
mobile system, we`re using a laptop in order to present the stimuli.
Recently, we had to replace our laptop but couldn`t find any new laptops
with built-in parallel port. 

I know that it is a bit out of the scope of this mailing list - but I was
wondering if anyone has experience with this issue.

Thanks!
Ido
