Currently Playing: No ISA Slots? Networking the IBM PS/1 by Parallel Port

How do you network a PC without expansion slots? In this episode, we take a closer look at a Xircom Pocket network adapter, that connects through the parallel port. And since this one specifically is a Token Ring adapter, I'll also deal with the DOS networking stack using Novell LSL, the TRODI ODI driver, ODITRPKT as a packet-driver bridge, to get mTCP working over a 16 megabit Token Ring network. And besides: Does it work in the IBM PC Convertible? In this episode: 00:00 Intro 00:46 Insights Into Network Adapters for the Parallel Port 03:08 Where To Locate The Xircom Pocket Token Ring Drivers 03:39 How Parallel Port Mode Matters For Throughput And Transfer Speed 05:03 The First Test Run On The Token Ring Network 05:56 How To Make mTCP Run Using ODI Drivers And Shims 🔔 Subscribe for more retro hardware adventures!
