The back of the laptop: There's a barrel jack, then 4 IDC connectors. The left most is 2x8, then 2x6, 2x20, and 2x40 https://digipres.club/system/media_attachments/files/112/215/120/043/106/656/original/05a9859f64543e1c.jpeg
Back of the laptop, we've got a power jack (12V 1.5A), and 4 slots.One is PS/2 keyboard/mouse and VGA, I think one is GPIO, the far right one is ISA, and I'm not sure what the other is (I don't have my manual handy)
