| The system is compatible to [[builderpages:rhkoolstar:mc-2g-1024|this]] CPM Software collection (download [[https://retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:rhkoolstar:mc-2g-1024.zip|MC-2G-1024.zip]] ) here in the forum - with one exception: The transceiver of serial-B got its own I/O-address. Probably that will affect MP/M-II and every software using serial-B. The baud-rate gen. keeps its I/O-address. I installed the system18.img on the SD-Card. | The system is compatible to [[builderpages:rhkoolstar:mc-2g-1024|this]] CPM Software collection (download [[https://www.retrobrewcomputers.org/lib/exe/fetch.php?media=builderpages:rhkoolstar:mc-2g-1024.zip|MC-2G-1024.zip]] ) here in the forum - with one exception: The transceiver of serial-B got its own I/O-address.

| //**I2c-EEProm-Clock-Module Adapter**// | //**I2c-EEProm-Clock-Module Adapter**// I've slightly modified the old adapter this way, that the DS3231 clock module is now soldered to the PCB. Still remove the old pinheader and solder a new straight one the IC side so the module can be soldered with the battery holder on top to the PCB. See picture 1 below. A 3D view is included as a subpicture. The two IO's on the I2C Header are renamed to INT1 & INTB. At present they are not used as interrupt input, but they are now additional IO's of the PIO-Port0 on the Joystick PCB. More in the Multicomp System Manual downloadable below. All data is in the archive “Multicomp-July-2019_V1.0.0_I2C-Clock_EEPROM-Adapter.tar.gz” |
