 The Z180 Mark IV is a single board computer, meaning it may run stand-alone. It also has an interface to the RetroBrew bus (ECB) for access to additional peripheral boards. The Z180 Mark IV is a single board computer, meaning it may run stand-alone.

 +=== Test ROM TEST0.BIN ===
 +
 +This {{:​boards:​sbc:​z180_mark_iv:​test0.zip|ROM}} ​ provides a suite of tests to confirm the operation of the Mark IV board.
 +
 +Requirements:​
 +
 +  * SD Card installed with D3 LED
 +  * Bicolor status LED
 +  * 18.432Mhz clock
 +
 +Tests:
 +
 +  - Check correct installation of address jumpers.
 +  - Determine the processor version.
 +  - Check the serial interface signal CTS.
 +  - Terminal output verification.
 +  - Keyboard echo test.
 +  - DS1302 & NVRAM test.
 +  - Check SDCard switch statuses.
 +
 +Initial operational status is visually identified by test 1-3 flashing D3 in a sequence of 5-flashes, then 3-flashes, then 1 flash.
 +
 +See the 0README.TXT file for more detailed information.
