Why does my Model 4 external drive plug directly into the IO bus if the bus is not set up for hard drives? Is the hard drive controller mounted in the hard drive cabinet? -- Marcus

Yes, there is a hard drive controller mounted in the hard drive case. The old five meg drives that radio shack was selling had a Western Digital (WD-1000) controller in them. This controller could then operate up to four hard disks. The 50 pin bus is an IO bus, and in addition to running a hard disk controller, you could have things like JoySticks, Clock Cards and Analog/Digital types of interfaces (including the Orchestra-90(TM) Synthesizer) ...dewitte -- DeWitte Wilson <wilso_d@cs.odu.edu> Old Dominion University Sysop - The Mod III BBS 804-424-1215 [300=>2400] 8N1 "We are the keepers of the Sacred Words.
