  1. No it was NOT my request, it's from a SDX user and I asked you not to shoot the messenger... and you did just now. 😢
  2. It's just a small DOS version, mate. No high-tech multi-purpose OS. Sector 360 is as described above, perhaps you can use byte 5-9 ? [edit] or word on byte 1,2 is larger then word on byte 3,4 [edit] ID-values are $40-$7F I used the Atari Tech Manual as template and DOS 2/2.5 is the most used. For the other question I had: I do have an LiteDOS-XS upcoming in -SE format. 🙂 It was almost ready back in May, but left it to do other things. I will review the code and make it ready for upload. Atari BASIC:
  3. You can still read LiteDOS disks as discussed. Since write-support is not supported in ATARIDOS.SYS, nothing changed in that respect. I guess. Some tech-info: The ID-byte -SE (sector 360, byte 0), bit 7=0 and bit 6=1. The rest of this byte is the cluster-size (1-64 sectors/cluster). Directory-size equals 2 times the cluster-size to match things up with previous versions. Also starting on sector 361 until the end of the cluster, then wraps to the beginning. Further more: Sector 360 is more DOS 2 like, bitmap starts on byte 10, byte 1-4 reflect size and free space, byte 5-9 are zero. I had plans to support writing to DOS 2 and compatible formats, but canceled this on release. I do not want to f*ck up other format disks... But LITEINIT can/does convert any LiteDOS to LiteDOS-SE Grtz, Sijmen.
  4. Just in case nobody noticed; LiteDOS-SE can boot over a 19k2 BT-connection on a stock machine. No need for replacing the OS or other soldering/modifications. And yes, -SE stands for Second Edition. The 1024 bit cluster-table gives room to 1000 files on a 16mb partition .
  5. Latest build now online. (23-october-2021) LiteDOS.DUP when copying from/to the same drive it asks for source/target disks. This was already in the code, but I forgot to output the question to the screen.
  6. Being fixed at the moment. The colours flash for a reply, but I forgot to show the message source/target.
  7. Sorry for this, but I have send you a personal message some time ago. Grtz, Sijmen.
  8. The 1450 was not mine, sorry. Yes it's fully functional(*), I repaired it for my two friends who own it. For as I know, there were no additional tests in the self-test. Except the presence of the voice. *) After replacement of the drive-mechanics, PDD-enable_switch and logic-IC...
  9. Perhaps old news, but Robert de Boer designed a replacement part. https://github.com/redhawk668/Atari-CO60472-Delay-Line-Replacement?fbclid=IwAR2Yd5eRECxTawmney_slNUrRYCJuJ_lSuKppwUCzu2NF2S9BSzfqOCLdRQ https://github.com/redhawk668/Atari-CO60472-Delay-Line-Replacement/blob/main/README.md
  10. Standard 850 protocol to me. Works for me perfectly. I use this tool to change my config. FujiNet.xex
  11. I think I found a bug in ATBasic 1.57 While coding/debugging LiteDOS It goes like this: SAVE to disk and we get an error like 162, disk full. IOCB #7 is not closed, data still in the disk-buffer. I swap disk. DIR to see if there is room. IOCB is closed, DOS writes its buffer to (the new) disk, and re-opens for DIR. Oops? Compared to Atari BASIC, it closes the IOCB immediately following a SAVE-error. Grtz, Sijmen.
  12. Warp 6, nice 🙂 I didn't came faster then 444 kb/s That is with A/C/E and with checksum. No block mode though. Grtz!
  13. No idea yet, what went wrong, but this is the correct file: Last firmware update I did for MyIDE-I is here (4.8.0A, unreleased beta with bugfixes to the -05 version). https://www.atarimax.com/flashcart/forum/viewtopic.php?p=9942#p9942
  14. I have my WARP-code still at hands. It can do 420 kbit/sec easily (without block transfer). Yes, ANTIC/NMI off. Currently FujiNET is the only device (beside my SIO-2-arduino) with external clock. But the firmware of Fuji does not lock this. On IO-error it hops to 19k2, then to pokey-divisor_X and back. Grtz! [edit] (*) All caps removed on the pokey-lines !
  15. These are generic eeproms I opened mine, to have a look. ST (maker) M29F010B (1 megabit) This is the transparent one, early versions were black, you can easily open them. They are not glued, just pressed together. I use a Transcend 128mb, no problems, with the latest firmware I created, the one you downloaded. Black screen, means, eeprom erased, nothing programmed.
  16. Last firmware update I did for MyIDE-I is here. https://www.atarimax.com/flashcart/forum/viewtopic.php?p=9942#p9942 (2017)
  17. 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 $8F4 In theory, a loader, can be much smaller....
  18. 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.
  19. 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!
  20. 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. https://github.com/FujiNetWIFI/fujinet-platformio/wiki/SIO-Command-%24DF-Set-External-SIO-Clock The code is a bit tricky, since switching from asynchronous to synchronous is not that straight forward. Grtz, Sijmen.
  21. 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!
  22. Update to MyIDE_Only #7 ? That could fix some issues with the stock flash-content. http://www.mr-atari.com/Mr.Atari/MyIDE-ONLY/ Grtz, Sijmen. P.S. you do know atarimax has it's own forum, right?
  23. It there a all-in-one zip file with the patched versions?
