os-v-131.zip

Download os-v-131.zip to upgrade to the latest Apex II operating system. Once downloaded, unzip the file into your Apexware directory.

This new release provides improved terminal operation in two different areas. Those areas include:


1) Parentheses Operations

The parenthesis handling routine had been amended to ensure more predictable operation when parenthesis extended both below and above address 10000h.
2) "Sleep-Mode" Operations

Every 7.5 seconds an interrupt is generated by the wakeup circuitry in the APEX II. This interrupt is used to power down the unit after a user defined period of time. To ensure more reliable and predictable results we have made improvements that will completely restore internal memory and totally re-write the LCD with the same information that was present prior to entering into the "sleep mode".

Instructions are included in with the Operating System Upgrade for specifics on syntax and technical instruction on how to access this area of memory.

NOTE:
Make sure that all files have been retrieved/downloaded prior to an operating system update. The update will overwrite all programs and files in the unit.
