CS Dept. Lines: 18 The PC-XT/370 contains a card with a 370 processor on it. This includes a couple of Motorola 68000s with a custom microprogram to handle 370 instructions and floating point. This gadget is intended as an alternative to a 3270 terminal at an IBM shop. It really isn't a stand-alone machine, it needs to be wired into a 3274 communications controller and talk to a mainframe running VM/CMS. (Don't you love all these funny box numbers?:-). The operating system is pretty much regular VM/CMS. A large part of the PC's hard disk is used for the user's local files (the A-disk in VMspeak). The PC user can link to other minidisks on the mainframe to access system files, etc., just like one links to system minidisks when logged on to a regular VM/CMS system.
