- FO 10:07 PM Feature #73: Implement ATX disk image support
- Pleased to see it looks pretty simple, so we should be able to plug this in without too much pain.
- FO 10:05 PM Feature #73: Implement ATX disk image support
- Ah, that makes more sense. The loadAtxSector seemed to be missing all the timing I was expecting, then I saw the phantom sector hack comment:-)
There are a couple of registers available to the ZPU, one has the current time and one del... - FA 09:50 PM Feature #73: Implement ATX disk image support
- Here is my current work-in-progress code that tries to emulate accurate disk timing:
https://github.com/kbr-net/sdrive-max/blob/v08/atx.c
The SD card is read using the faccess_offset() function. Data is stored in the global "extern... - FA 09:48 PM Feature #73: Implement ATX disk image support

- What is the basic interface?
If I receive a command packet, can I send it to the atx handling code and it returns me a packet to reply with and a delay? I guess it would need to call me back to read/write from/to the sd card too. - FA 08:29 AM Feature #73: Implement ATX disk image support
- The SDrive Max project has ATX disk images working including many forms of timing-based protection. The code is written in C and is structured to make the Arduino-specific easy to replace. This can hopefully be ported to EclaireXL.
- FA 08:27 AM Feature #73 (Closed): Implement ATX disk image support
- FA 10:06 PM Feature #72: Implement stock Atari 400 mode
- Most of this is probably not relevant here, but my understanding of the differences are:
1. Membrane vs. full-stroke keyboard.
2. It was originally sold with 8K of RAM but most sold with 16K RAM. Atari did sell a 48K RAM expansion ki... - FO 09:10 PM Feature #72: Implement stock Atari 400 mode
- Are there any differences from the Atari800 mode? I guess 2 joystick ports. I guess also allowing less than 48K of ram (though that could be the 800 too).
- FA 08:20 AM Feature #72 (Closed): Implement stock Atari 400 mode
- There are certain titles that require OS-A to run (Megalegs, Ghost Hunter). It would be nice to have a "stock Atari 400" mode that runs OS-A with 16k of memory.
- FO 09:19 PM Bug #66 (Closed): Odd flash behaviour on new boards
- I've received my board a few months ago and am unable to reproduce. Working fine as far as I can tell with the 64KB flash size.
I'm guessing I'd provided Panos with a strange test core which we ended up flashing. No idea what it was d... - FO 09:16 PM PokeyMAX
- I've spent some time this year working on a new FPGA board that fits into the original computer, to replace the pokey chip. I've got it sitting in my Atari 600XL and to me it works pretty well.
I'm planning on doing this with all the... - FA 08:17 AM Feature #68: Implement stock Atari 800 mode
- Updated this issue to encompass further issues with the current OS-B implementation.
