MSX2 Utility Board V1 Build info
Status of my MSX2 Utility Board build.
I've made enough progress on the board be able to run a simple monitor out of the on-board EPROM. I've had to make 2 changes to the board for this. These changes are documented in the file area under "Builders Journals\Neil B"
Based on my work I believe the following are working (based on the fact that my monitor is running out of the utility board EPROM/RAM using the UART to communicate).
* 8255 PPI
* 16550 UART
* 32K EPROM at $0000-$7FFF
* 32K RAM at $8000-$FFFF
Still waiting to be tested:
* Printer Interface
* Slot Selection Logic
* Remaining 32K RAM (mapped in the slots)
