Beginning of Architecture Construction
04/07/2018 at 07:04 • 5 commentsHere's my firs couple of hours making a simple conceptual flowchart for the architecture of the 8-Bit Portable Computer.
I don't have the protection circuitry for the 74LS612 MMU finished, so I didn't want to go into a complete electrical schematic.
The things missing in this diagram are:
- Memory-mapped ROM
- Memory-mapped IO
I anticipate that I may need a second 6522 ACIA in order to debug the system.
At the moment, most of the components for the computer are remaining very cheap, so I am hoping this may be able to be copied and built elsewhere.
