Hi,

to get back to the root of this thread here an update to the emulator.

https://dl.dropboxusercontent.com/u/320 ... ppleII.zip

It is a pretty complete Apple IIplus emulation. This version boots into PRODOS from a SD-Card (see readme.txt). There are quite a few changes. More Documentation and a code Clean-up is under way, but not at a high priority as I received the hardware I ordered to finally create another fancy 65C816 based computer, but that's another story.

Regards

Peter

Hi Peter:

Nice work. Have you updated schematic to show AVR connections for SD card, Sir?

Cheerful regards, Mike

Hi Mike,

thanks. No, I haven't updated the schematic with the SD card. I was very lazy, just took the SD-Card adapter from a Arduino Starter Kit I have purchased about 1 year ago. This one has only a 3V3 voltage regulator and uses voltage dividers with 1k and 3k3 resistors for the input signals to the SD-Card. You need just to connect the signals MISO, MOSI, SCK and SS.

Regards

Peter

Peter, I registered just to congratulate you for this wonderful project. I'm an old Apple user, and now I'm into AVRs, and it's just great to see both worlds integrated.

I just downloaded the project and I plan to study it in detail, it's a great learning resource.

Many thanks, and please keep up the awesome work!

Hi Eduardo,

thanks a lot for your compliments. In the meantime I have not done a lot of updates to this project as I really wanted to finish my other project viewtopic.php?f=4&t=2878 first. And I think updates to this project will take some other time, as I want to add first CF-Card support to my real 65C816 system.

If you have any questions feel free to ask.

Peter

Hi Stian, Vladimir,
I'm wondering - are your projects working now, and have you published source for them anywhere?
