Widget 82 error.

(1/4) > >>

bmwcyclist:
My solenoid was not retracting. I adjusted it as per troubleshooting instructions from Sun re marketing.

Solenoid appears to be working properly, but I am getting an 82 error.

I noticed when the heads are in the center of the drive the horrendous noise goes away. I don't know if that's irrelevant.

Any suggestions?

By the way, I don't have BLUN a disk format that I can use with the floppy EMU.

Here is the video https://youtube.com/shorts/qLkUoe_MRj4?si=rPQIEWjpsAYduMhY

In the video it looks like maybe the wire going to the solenoid is rubbing on the flywheel... (?)

Assuming BLUN was supposed to be "BLU in" --

Although I suspect BLU won't be helpful here compared to something like https://github.com/stepleton/NeoWidEx, I think the straight DC42 file should work after unzipping, is that not the case?

AlexTheCat123:
It doesn't appear that your drive is making it through the self-test that occurs right after the brake releases. The heads seem to move once and then give up. You should be seeing a bit more movement, and the heads should be slowly sweeping the entire surface of the disk as they perform a seek test.


I'd suggest hooking the drive up to either NeoWidEx or your ESProFile (with the switch on the ESProFile PCB flipped to the DIAG position) next. If you choose ESProFile, just connect to the board over serial at 115200 baud to access the diagnostic interface.


Then maybe try to read the status of the Widget controller and let us know exactly what it says. On ESProFile, it's the Get Controller Status command under the Widget-Specific Commands submenu, but I'm not sure what it's called in NeoWidEx. That should give you a good bit of info about the health of the controller, and can help us figure out where to look next.

Just the angle of the camera.

Nope. FloppyEMU does not show it in the menu.
