Memory Cassette Compatibility
Be aware of the following restrictions when using a Memory Cassette containing a
program that was stored from a CPU Unit with a different version of system software.
Note 1. The display functions (display clear: -CD@ and day/month
display: DAT1) cannot be used and will be ignored.
2. Only the memory area ranges supported by the pre-V1 CPU
Units can be used for Timers, Holding Timers, Counters, Weekly
Timers, Calendar Timers, and Displays (i.e., only half of each).
3. Only 6 inputs and 4 outputs can be used in the CPU Unit I/O bits.
Any others will be ignored.
4. Twin timer operation for timers, operation between days and pulse
operation for weekly timers, the 8-digit counter, and 8-digit
comparators cannot be used. New Zealand and Australia cannot
be set for Daylight Saving Time (DST).
