TRS80 Model 1 Level II

Good! If you have the disk controller in the system (read : If you have the Expansion Interface connected), then the machine tries to boot the disk _before clearing the screen_. If you don't have a disk in the drive, then you get a screen of garbage. Try turning the machine on [1] (or pressing reset -- the button next to the expansion edge connector on the back) while holding down the BREAK key. That will force it to ignore the disk controller and go into BASIC (press ENTER at the MEMORY SIZE? prompt). Or, of course, put a bootable disk in the drive and press reset [1] There's a right order to turn things on : Monitor, Expansion Interface, drives, printer, then put in the bootable disk and turn on the keyboard/CPU. Do _not_ have a disk in the drive when powering up (or down) the drive or expansion interface. It will (not may!) become corrupted. The M1 doesn't use 2114s :-) -tony
