  1. Thanks for typing these in and to those helping to debug them. Could you possibly post the fixed disk images once you have made the corrections? I would love to try them. thanks
  2. Thanks for this, I will try it out this weekend w/ my //c. Love trackers.
  3. I have my original setups from back in the mid 80s. 130XE and Indus GT drive (cannot remember what I used for a monitor back then, I think it was just a TV). Saved my paper route money forever it seems for that rig. A year or so later a 520 ST w/ SC1224 (I have a 1040 currently). Still have the receipts for both (Lyco and White House Computer)! I imagine like many others in this thread, we have a wee bit more stuff than our original gear.
  4. Sorry for the necro, this seems to be the only thread I can find on this topic. I had read in the past there were issues with the disk images available for Questron as far as the ending. I plan on playing on my 800XL, but wanted to find good working images (vapi, or flux images would even be better) before starting to play this. Hopefully there has been some resolution since 2012...
  5. This looks pretty great! Can anyone comment on the differences between this and the MicroFox CF flash interface (which I currently have)? A big one is obviously SD -vs- CF which are becoming harder to find. Just wondering what some of the functional differences/improvements are.
  6. Only took me two years to get around to this. Only seems to happen with some directories. I have a similar hierarchy under dsk, which has the same named folders and it comes up almost immediately. The one shown in the video holds all my .xex files. Seems to take about 45 seconds to show a-z and a couple other directory entries. If there's any thing else I can do to help debug just let me know. https://www.dropbox.com/s/v5205eilf53j3rm/IMG_8999.MOV
  7. Wondering the same thing, interested in picking up one if/when they are available again.
  8. I did get to the bottom of this. Replacing the mech fixed it. I'm surprised it could work intermittently like that, but maybe it was just the head.
  9. Thanks for the info, I had the JU-475-4CGJ written down in my inventory as a 360k drive, seems I was wrong there whenever I had written that down. I don't think I've ever run across an intermittently working head. The drive works, it's just slow to load or just gets an error every other "beep" and even then seems to load. I'll dig out another 360k mech, I believe I have a few more PC based ones... will 1050 mechs work? I have a bunch of those. My guess is no since they aren't "PC" mechs.
  10. The drive is back on my bench and I decided to try the other mech I had again just to be sure. I have a feeling that it is not compatible. It fails in a similar way, but the timing is different. I did change the DS jumper to what I believe was 0 (and pretty much every other setting and the same behavior). Model is Panasonic JU-475-4CGJ. For 360k mechs I also have a Teac FD-55BV and a Panasonic JU-455 I could try. Is there a way to tell if a mech is compatible? And related to this, are the symptoms I've described so far, very intermittent/slow read ability indicative of a head going/gone bad?
  11. I did find this on the atarimax forums regarding the beta firmware "This includes fixes for a few hardware and firmware bugs that may not impact many people. It also includes support for 64kB "Activision" cartridges less eeprom support."
  12. Hmm, so that is most likely working OK. I'll try and eyeball it for rotations, but I'm not sure what to check next on the control board. Are there some common failure points on the board other than the SIO jack solder joints?
  13. I’ve also tested with an 800XL and seeing the same behavior. Does the RPM output seem legit? I had tried a different mech and got the same behavior, it seems improbable 2 mechs could both have super slow RPMs. The control board seems to be the issue and I‘ve already redone the solder joints of the SIO ports and checked the regulators. What’s left on the board? Also, I cannot find the pot to tweak the motor speed to save my life, where is it? I don’t plan on touching it unless it needs adjustment, just curious to where it is.
  14. Was able to check out the RPMs today, given how slow the drive works when it does work, this *kinda* makes sense. But I would have figured that there was a range of RPMs that the drive would work (around 300rpm or so). It's also possible the program isn't correctly reading the RPMs. I've attached a screenshot. Some disks wouldn't register at all. One of the disks that loaded fine, but very slowly did give some readings of 36 and 37.
  15. Hmm, that makes a lot of sense. Is there a way to improve the clamping force? I do plan on verifying the RPMs soon. And I did look at the 5 and 12v with my o-scope. Very clean, I didn't see much ripple, etc if any.
