I have fixed most of the video issues and can reliably boot into Apple ][ mode. I was planning on posting some pictures, but I got side tracked. I finished the 128K memory code and also finished the Floppy disk emulation. I say finished, but it really is not finished until it is tested. I have done almost no testing on any of these new features. The memory I can test using an assembly language program. I am working on it now. When the memory code has been tested and debugged, I need to switch over to the Apple IIe ROMS. This will give the 80 character display capabilities.

Well...mostly. Yesterday it looked like it was trying to boot. I was getting a ] at the bottom of the screen when I hit the RESET button. But the screen would not clear and the keyboard was not working. I should have cycled power and I would have gotten the screen to clear. Something about cold booting and warm booting. Today I fixed the keyboard, except for the space bar. And now I can run BASIC programs. I have not done much testing, but I have some issues that I need to fix. Of course, I need to fix the space bar. Also, the character K is replaced with G. Both if these are easy fixes.

I've got a backlog of projects, including:

1) Get my QRAM 1M Apple //e card tested and installed

2) build out my replica 1 Kit

3) Get 6 Apple 2s hooked together for some Music
synthesis, I've got 2 MIDI cards kits, but need
some 6850 and other chips.

I've got one Mountain Computer Music System (with light pen!)
Also have 2 Novation Apple-Cat cards now (8-bit D/A for more
elaborate sample playback.)

4) Put the 6522 on a prototype card, maybe along with
an FPGA if I can find the right kind of socket.
