Apple - ROMs

I have most of the software switches added to the code to make the system look like an Apple 2. The next task is to add ROM to the system. This ROM is needed for the Monitor, BASIC interpreter, and to hold floppy images while I write and test the floppy emulator. I was looking at Compact Flash devices that can be used under Prodos. The issue with these is the amount of prototyping needed to make them work. I was hopeing for far less signals. I looked at multimedia flash cards (MMC) also. They have less connections and this is probably what I will end up using.

Video done

I have not updated this blog in a couple of weeks. I have been busy at work as well as working on this project. I have pretty much finished the video section of the Apple IIE. All modes look good to the eyes. The FPGA board has switches that I am using to set the different modes.
