No PCI, but I do have VLB. Graphics card and IO card are in VLB slots. I have 20MB RAM. For storage I’ve gone through several old hard drives but they all ended up failing. So I went with a CF card to IDE adapter. Mouse is serial, because I don’t have PS/2. I use a nice mechanical keyboard with a USB to PS/2 and then PS/2 to 5 pin DIN keyboard connector adapter. I also have a gotek floppy emulator on it. I mostly use this computer to play around with Borland C++.
