Memory tests for the MOS KIM-1. This repository contains a number of different tests:
This is a port of the OSI memory test for KIM-1 memory layout and serial I/O. ttytest runs on the bit-bang serial interface included with the KIM-1. The Makefile target generates a MOS formatted hex file, which can be loaded into the KIM-1 using the built-in monitor L command. Interaction with the test is via serial. The test loads in at 0x0200 and fits in the onboard 1K of RAM on the KIM-1.
This test is primarily used to check out expansion memory on KIM-1s. Running the test below 0x0400 will clobber the test! Commands are:
Syntax T:<start>,<end>
Example: enter T040013FF to test 4K of memory above the base onboard RAM. A cycle count will be displayed, and an X will be printed ever 255 cycles.
If an error is encountered, the address will be displayed with the expected and actual content. Hit <CR> to restart the program.
Syntax: L:<start>,<end>=<data>
Example: enter L040013FFFF to fill 4K of memory above the base onboard RAM with 0xFF.
A splat * is printed on completion, hit <CR> to restart the program.
Syntax C:<start>,<end>=<data>
Example: enter C040013FFFF to check if the 4K of memory above the base onboard RAM contains all 0xFF.
Errors are reported as with the T command, a splat * is printed on completion. Hit <CR> to restart the program.
Assemble by running make. You'll need the CC65 package, srecord, and a working Perl.
