litedos xs?
litedos ro?
dunno, about apeloader as a standalone but why not? and lots of 3 sector loaders out there... wasn't this already covered
during some talk of loading disk stuff with a 400 etc...
food for search and thought in any case
what's the memlo of xs and ro?
But they are still handler based, so it installs D to the device-table.
-XS $BD0
-RO $9FF
Doing a destructive load, you can start at loading $8F4In theory, a loader, can be much smaller....

The later productions of MyIDE-1 have power on pin 20, yes.
So you can plug it in just like that.
No need to use the power-header.Pin 20 is on the label side, you can have a peak inside with a light.
Latest firmware etc, please vidit the atarimax forum.

* People that don't use SDX
* People that use SDX
The problem is more who use Fuji as stand-alone or not.
I have the same 'issues' when booting over SIO, I have a executable that loads and mounts the last stored Fuji-config.
I would suggest that FujiNet should restore the last configuration by it self when something else takes boot-control.
That works for any DOS or any one who uses Fuji as device (not stand-a-lone)
Is that workable Thomas?
So during powerup:
-if Something else boots, restore configuration.
-if Fuji boots, do the config stuff and end with OPTION to boot.
I really hope this can be done.
Later!

I have the feeling that you are not on the same page, so to speak. @xxl an unmodified 800XL can reach divisor 0 if either the device has proper Schottky diodes in place (I have seen that working on a prototype of @mr-atari, even higher bitrates when Pokey is externally clocked), or if you run your device through @lotharek's SIO hub, which has similar signal clean-up in place.
Edit: yes, SIO2SD should be able to reach divisor 0 with above mentioned solutions.
Maximum external clock speed is 4 cl/bit for POKEY to accept serial-data in the shift-registers.
That is what I found by trail and error.
That is a whopping 443 kbit/sec (or 44 kByte/sec) !
Called "project Warp-factor 4" back in the days.
My experimental device is a SIO2SD-arduino, with attached clock-lines.
FujiNet currently has the external clock enabled with programmable Khz.
But you need to remove the caps to make this work.

The code is a bit tricky, since switching from asynchronous to synchronous is not that straight forward.

One of my early production IDE interfaces.
Interface only, no boot-rom.
Should come with 2x 5.25"discs with software/drivers and a 3.5" disc for SIO2PC.
I don't see them often pop up.
Nice though, was fun times, using pole position cartridges and converting them.
Currently Atarimax has the rights to produce MyIDE-interface based hardware.
Later!

Update to MyIDE_Only #7 ?
That could fix some issues with the stock flash-content.

P.S. you do know atarimax has it's own forum, right?

It there a all-in-one zip file with the patched versions?

2nd : is illegal in LiteDOS, but also in SDX.
Please use another separator and it's ok.
Try my new LiteDUP, I mail it to you.

Check the door-switch.
Why the question about a fuse?

Here it is as a txt file.
Reading the source, the checksum location is skipped.

I fixed a broken console-switch for a friend some time ago.
It are the same switches used in Atari-Paddles.
So if you have some for spare parts, replace yours with it.

Thank you so much, this was easier then I thought.
It will help me a lot debugging special hardware.Nice.

You can't just change the protection on an address space range, something has to provide RAM at that address. One way is to write a custom device that has a memory layer to map 256 bytes of RAM there.
How do I write a custom device?
Is there a template I can download/use?
I know my way around in 6502, that's about it....
OK, I cut/paste your example of 8k cartridge and changed to this:
It does something, any good like this ???
Thanks!
---------------------------------------------
option "name": "256b D500-RAM";
Segment ram: {
size: 256,
source: "d5ram.bin"
};MemoryLayer wina: {
name: "D500-RAM",
address: $D500,
size: $100,
segment: {
source: ram,
offset: 0,
mode: "rw"
},
cart_mode: "left"
}; -
I have perhaps a very stupid question, but I can not find it or figure it out....
How do I change the memory map?
I would like to change D500-D5FF from mode --R to ARW
So it can be used as normal RAM
Grtz,
Sijmen.

This is intentional, both to prevent the emulated computer from opening huge files. This is particularly an issue with H6-H9: since the file is kept in memory to support seeking with EOL translation. You should have gotten disk full errors trying to write to the file past that point, however.
I could see lifting this limit for H1-H4: since in that case the data can be spooled to/from disk.
Any progress in fixing the 16mb limit?
One request, that is pestering me always, is it possible to include a tic-box in the device-list?
This to disable or enable devices.
That would awesome, when testing software on many different systems...
Thanks!

If that would be possible (or at least one specific Hx:), yes please.
I did not check for errors (on write), assuming when files are opened correctly, this should not happen.
So that went passed me.It had me puzzled for some time, since I was working on video-compression and I could shrink 500+ Mb into 16, lol...
Many thanks in advance ?

I have an issue with device H:
Most likely nobody noticed because of the file-size in "normal" use.
But when I output (or throughput) a file, it's output-size is limited to 16Mb.
All bytes beyond 16Mb are lost in space...
Can you have a look?
Thanks!

Move the chip to the far right.
Pin 1 to the left, that is correct.
That is how I use my programmer.
Mine has this symbol:

Better late then never ?

I have one too, from an Atari maintenance guy.
He told me it was used in testing 400/800 ports.- 1
