  1. Sorry for this, but I have send you a personal message some time ago. Grtz, Sijmen.
  2. 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...
  3. 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
  4. Standard 850 protocol to me. Works for me perfectly. I use this tool to change my config. FujiNet.xex
  5. 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.
  6. 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!
  7. 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
  8. 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 !
  9. 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.
  10. Last firmware update I did for MyIDE-I is here. https://www.atarimax.com/flashcart/forum/viewtopic.php?p=9942#p9942 (2017)
  11. 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....
  12. 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.
  13. 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!
  14. 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.
  15. 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!
  16. 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?
  17. It there a all-in-one zip file with the patched versions?
  18. 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.
  19. Check the door-switch. Why the question about a fuse?
  20. Here it is as a txt file. Reading the source, the checksum location is skipped. Grtz, Sijmen. From the OS checksum.txt
  21. 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.
  22. The back cover is really nice too, on my 'STARRAIDER' that is. Some say this is an early one, but the rom's inside aren't. Guess they went with what was on stock to produce cartridges.
  23. Thank you so much, this was easier then I thought. It will help me a lot debugging special hardware. Nice. 🙂
