  1. What is the power supply to the capacitive IC? Is it 3.3v from the Incognito? Where did you pick it off? I'm afraid of the capacitive IC output switching between GND and 5v if the 800 power supply is used - flashjazzcat talked about how sensitive the Incognito is to 5v with his own LED / ATR switch mod. Thanks!
  2. Installed my Incognito in a later model NTSC 800 this week. Noted a few things if it's your first one: As others have pointed out - don't trust the wiring colors for the wiring harness - look at the points you are connecting. Pin 1 of the headers has the square solder pad. My "CPU Board" is a very different layout than seen in the tutorials - the chips are in a different layout and the pin 1 end is at the connector side of the board... So count your pins on ANTIC to find 9 and 15
  3. Thanks for the 810 case Mr. Robot - decided to make it a bit more authentic (it was already awesome!) Added Power and Busy LEDs I took pics of project - let me know if you want a tutorial... IMG_3432.mov IMG_3432.mov
  4. As an aside, I picked up an MX-80 but it only has the text not the GrafTrax ROMs... Anyone have dumps of the GraftTrax ROMs so I can use these drivers? Thanks!
  5. Here is a link to find the stl file for the SIO socket (computer side) noted in the first post. No mention of where they found pins though... http://blog.3b2.sk/igi/post/SIO-konektor-v-pocitaci-SIO-connector-on-your-computer.aspx
  6. I've been working on a small project - after building an SdriveMax. I've wanted to make it smaller and internalize it. Have it working now. Pros: A little cheaper - no screen, no SIO plug Internal - less stuff to lug around Smaller - uses a smaller Arduino with the same chip (Arduino Nano) Powered off constant 5v rail of the main power switch, power controlled using the channel selector switch Built in the 7407 circuit so should play nice on the SIO bus Cons: Setup is hard - SDrive Max relies on screen calibration - I had to burn the EEPROM from a working SDrive Max using AVRdude over ICSP Future directions: See if kbr will release a headless firmware that doesn't stop waiting for initial screen calibration Make an all in one board that uses surface mount and doesn't require an Arduino Nano and a separate TF card breakout Questions?
  7. Thanks for releasing the information! Could you please post the installation instructions / modifications for an Atari 400? Thanks!
  8. First time trying this device - it's an SD to IDE adapter from AliExpress - and it seems to be working. I know people had some luck with the SD to CF adapter that then plugged into the CF to IDE carrier. This is one step simpler and I'm not sure anyone tried it yet (although electonically, it's probably very similar). So if you're allergic to CF it may be worth a go...
  9. Hey! That sounds a lot like the behavior I reported earlier in the thread... Try setting the jumper on the CF adapter board to slave mode, then turn slave mode on in the U1MB setup AND in the loader. Reboot Do they see the drive as slave now?
  10. Would like to try swapping the XEL CF with yours tomorow and see if we get the same result. Would go a long way to troubleshooting. Yeah I will be in the next dog house over. The girlfriend doesn't think it's a good use of my weekend
  11. Yes - I was planning on running by with the 1088XEL and a homemade hand wired SD2SIO
  12. I'm still working this problem - on the bright side, the CF cards seem to work with jumper off or in the 2-3 position - away from the 44 pin connector if slave mode is on in U1MB and the XEL Loader. - I can load files in the loader and I can see APT partitions in SDX under the U1MB. Still frustrated by it, however since I seem to be the only one unable to use the XEL-CF in Master mode. Reflowed all the solder points on XEL-CF and CF adapter. I checked continuity of pin 1 of the Master/Slave jumper - goes to pin 39 of the CF card (/CS) and pin 2 goes to ground on multiple pins of the CF and 44 pin connectors. Ground is carried to the XEL-CF. Tried multiple CF cards of various sizes and manufacturers. (see below) Two 8MB cards were recognized as Master - but seem to be erratic. I verified that in the CF world - taking pin 39 (/CS) to ground will put the card in Master mode. I may just build a second to see if it exhibits the same behavior - pointing to the CF cards or mobo. If anyone has built one around Indianapolis, IN would love to meet and try a working XEL-CF and card. Any other thoughts from anyone?
  13. I bought mine from China and it flashed with HxC just fine!
  14. So I asked FJC about this behavior - he pointed out I should have Slave Drive turned off... It was - so I turned it ON, with the jumper on my single CF board set furthest from the 44pin cable connector - and FDISK can now see the CF cards - all of them and format them as APT. If I change the jumper - No APT Devices, and if I turn off slave in the U1MB bios - No APT devices. Does this point to a short somewhere in the master/slave pins?
  15. Thank you Dr. V, Unfortunately, I can see the (now 3GB) FAT partition in the XEL loader, but still running FDISK v4.5 I get "No APT Devices found" even with the about 1GB non partitioned space. Do I have the right version? Using FJC's toolkit v5 which has FDISK v4.5.
