This seems like an impossible driver to find. I found it on a canadian toshiba ftp. It is no where to be found on toshiba's main site. These are the drivers that worked for me, to get the PCMCIA slots to work with windows 95B.
If they don't work for you, try updating the bios of the laptop first, but they should work.

DriverGuide.com - Using DriverGuide's Installer
DriverGuide's installer software (Windows only) simplifies the driver installation process. It safely downloads and verifies your driver and then assists in the installation of it.
You may notice that the file size of the installer software is much smaller than the file size of your actual driver. The reason is that first the installer setup file is downloaded, and then the installer software does the work of fetching
your driver from our fastest download server.
The installer setup file has been certified safe by leading-class virus and malware scanners.
Sometimes anti-virus software can report false positives. If this happens to you, we encourage you to submit the file you download to VirusTotal (a free, independent service which identifies malicious content) where you will see dozens of other anti-virus scanners report the file is perfectly safe.
The installer setup file may include a purely optional advertising offer which you are free to decline. We only work with trusted advertising partners.
Note: Windows only. Mobile, Mac OS and Linux users can choose other download options by deselecting the installer checkbox below the download button.
