The left side of the laptop: CF card slot, USB slot, and a 2x10 IDC connector https://digipres.club/system/media_attachments/files/112/215/115/417/011/552/original/865a5324b5a381c4.jpeg
Left side has the removable hard drive (CD card), USB slot (which is just used for mass storage, it's not generic USB host), and an unlabeled port. I believe this one is designed for parallel port use, it came with an adapter.
