Below is the documentation for the files which are to be run on a disk as a burn-in for Kaypro computers. In order to work, they must all be PIPed to a diskette which has been SYSGENed. AUTOON.COM is a routine which will turn the disk in A into an auto boot which will subsequently (when cold or warm booted) come up and look for the program AUTO.COM to run. AUTO.COM is a routine to disable the auto boot function which was enabled by AUTOON.COM, and also to tell the system to submit the file TEST.SUB. This means you can auto-boot a submit file. AUTOOF.COM is a routine to make the disk in A a normal (not auto-boot) disk. TEST??.SUB are a series of submit files to save and erase 5 files to check whether the system can successfully do this a number of times. TEST.SUB will start TEST1.SUB and so on until TEST10.SUB, which as its parting gesture will start TESTM.SUB. TESTM.SUB is a submit file to run the two memory tests TESTLO and TESTHI.COM, each of which will test a portion of memory for 0FF hex times and then boot the system. If they were star- ted from a submit file then the next line in the submit file is run. As a parting gesture TESTM will submit TEST.SUB which will start the cycle all over again. TESTLO.COM is a memory test which will test the memory from 0000 hex to 8000 hex. The sequence fills memory with the low-order of the address of the memory cell to test and then tests for that value to be there. There is a delay from when the test begins to write the cell until the cell is written. The next step will fill all the memory cells with the high-order addresses and will check with a delay between. The object of these two exercises is to check that the memory chips can successfully decode the appropriate address. Next, memory is filled with and checked for AA hex and 55 hex, which will de- termine if all bits can be set to a 1 and 0. In all cases, if an error is detected the address as well as the byte we want and the byte we got is reported and the pro- gram will stop. TESTHI.COM is the same as TESTLO above except it tests from 84DC hex to FFFF hex. ******************************************************************************** The following is documentation for the other files on this diagnostics disk. ALIGN.COM Fills the screen with the letter "H", with two lines of print to mark center of screen vertically, and two flashing charac- ters in the center of each line to mark center of screen hori- zontally. Makes CRT adjustment easier; reset to exit. D.COM Lists directory entries alphabetically; it also shows the amount of space each file occupies on the diskette. DU.COM Diskette utility program that allows reading from or writing to any sector on a diskette. DUMP.COM This version of DUMP displays the ASCII characters beside the corresponding line of hex code. HOF.COM For use with the Dysan Alignment diskette (Part No. 800183), it steps the drive heads in and out in response to the cursor keys on the keyboard. RDOT.COM Alternately writes to and reads from each track and sector of diskettes in both drives; then displays the number of retries for each sector, track, and disk. Begin this test with drive B door open. SPIO.COM A test for parallel and serial port functions, it requires a test jig consisting of: 1) a parallel connector with a piece of cable connecting it to a breadboard with 8 LED's each wired through a 200 ohm resistor to the +5V line of the main board power connector. 2) an RS-232 connector with pin 2 jumpered to pin 3, and pin 8 jumpeered to pin 20. 3) a jumper between pin 1 of the parallel connector and pin 5 of the RS-232 connector; also a jumper between pin 11 of the parallel connector and pin 4 of the RS-232 con- nector.
