BRIEF DIAGNOSTICS DESCRIPTION All of these diagnostics are run under CPM before booting Micronix. INTEST.COM Initialize clock interrupts and run continuously printing dots on the screen forever until interrupted. Failure indicated if dots stop spontaneously. Without auto line feed on terminal only one line of dots is printed and failure is indicated if interrupt (any key) fails to abort test. CHECK.COM Non-destructive read only test looks for any bad sectors in a Micro-Winchester drive. RAMCK1.COM Quick check of extended memory prints Gs for each 64K block. Should display four consecutive rows of Gs for Micronix minimum configuration. Stopped with system reset. RT3@MULT.COM Very thorough memory test on first 64K only. Several tests for each pass, the last of which prints out only a single line of Ms and is running op-codes from the area under test. Failure indicated by printing ?s or stopping.
