No not really.
I am not a hardware guy at all. Yet even I could tell from a simple glance at the image that the "Reimaged XF551 Original Disk Drive Controller v2.0" was a dual layer PCB with traces on both sides, whereas the stock XF551 controller board was single sided.
It simply made no sense that this new dual sided design would be an exact replica of the layout of the stock item.
Furthermore, a review of the text of the entry on Dropcheck's website from time states:
"Two years ago I started playing around with the idea of redoing the controller board. I wanted to correct some of the design failures and hopefully add additional features. Fast forward to today and I now have a finished product. It reduces the size of the original board, while using an industry standard double sided pcb. It also incorporates an easy method to switch between two OS by using a SPDT toggle switch connected to the OS header. Mod board connectors built in allow upgrading to a daughter board allowing numerous additional features. An internal SIO header provides future internal upgrades. Best of all it can simply function as a dropin replacement for the original controller board."
Furthermore I will state that I own one of these "Reimaged XF551 Original Disk Drive Controller v2.0" boards and have it in my 3.5 modded XF551. It has worked flawlessly from day 1, reading, writing and formatting without error. I know Dropcheck advised us that some units were not working as expected and offered fast and simple remedies.
So even if this new design turns out to have some flaw I have no doubt she will continue to support her work 100%, and the fact that this new design is not a xerox copy of the stock XF551 controller board is no reason to reject it as a suitable basis on which to repair an otherwise useless XF551 drives.
Original website as of Dec 2015 for reference:
The fact that it was very clear to you, doesn't by default prove that it was very clear to me. (That is exact the point I try to make all the time)
Why do you ignore the fact that in most of my posts here in this thread, I try to explain why it was unclear to me, why I got confused. The only thing you are doing with your post is repeating and proving (again) how stupid I (Prowizard) was that I was not able to see that this isn't a 100% copy.
Sorry, but I really did not see that in 2014/2015. I remember that I was absolutely convinced that I was ordering an original board. I really was thrilled to see it. My conclusion was: there is a re-designed board, and an original board. I wouldn't have bought it at the first place, if I was not convinced I bought an ORIGINAL remake. That is how I thought. You obviously wouldn't think that way, but I did. And I still can understand why, although you have made your point very clear how stupid that was from me. Thanks for that. Afterwards I see my mistake. I already wrote that in other posts. But you seem not to want to see why I got confused. It is really not THAT stupid that I made a mistake.
A few thing by the way to take in mind:
1. You live in NTSC land, I in PAL land. So you want to prove to me that the boards are ok since your board worked fine from day 1, while you are using 60Hz AC power and I use 50Hz AC power? If you do not want to prove anything, what is then the need of telling me that YOUR board worked fine from day 1?
2. You're trying to prove that the board was ok, while you are using it in a modded (3.5"!) xf551? So the fact that it works well in your NOT ORIGINAL 3.5" XF551 should prove that Dropcheck did the design right and that I have no ground to be critical? If you do not want to prove this, again ... what is the reason you are bringing this up? It is completely useless in this debate.
3. And why did you leave out the most important part in your citation of the website? Let me add it here, and please look at the part I emphasized.
"The original Atari XF551 Floppy Disk Drive came to market in 1988 to little fanfare. It was backward compatible with previous Atari DOS versions, but added the ability to read and write double density and double sided disks through the new DOS XE , sported the new XE color line and used an industry standard 360k floppy drive. It also was cheaply made, using a controller board that was little more than single sided perf board and a poorly done power supply that barely provided enough power. Most problems can be traced to the breaking of traces on the power switch and input jack or SIO connectors. Sadly the drive came at the last years of Atari’s 8bit reign. Sales never approached that of the 810, much less the 1050."
So the "I WANTED TO CORRECT SOME OF THE DESIGN FAILURES" was -for me as a reader- referring to that part I emphasized. I thought: ah you corrected those design failures, like bad traces and all. My fault is that I did not understand all of the text and indeed I should have asked more clarification. For me though it was crystal clear what the improvements had to be. I was wrong, my fault, my confusion.
But like I wrote already, the fact that the replacement board did not work, is exactly the reason why I asked the question in my first post in this thread. If you correct something, but it turns out that exactly that correction means that the board does *not* function properly, why did you " improve" it in the first place? How well did you test it? That is exactly why I asked whether can I expect these NEW boards to work properly. I would say, at least in my XF551's the original power-circuit worked perfect, so I'd say: keep that circuit 1:1 100% te same. So why can't I ask a question about that about the boards offered this time?
To me this is a legitimate question?
Indeed Dropcheck offered repairment and replacement. She offered the right aftersales support. There was nothing wrong with that. I never wrote here that that part of her shop is bad. She is a good person, but still ... A good person can be asked questions too you know.
And that is exact the problem with threads like this one. I simply asked a question. Kheller2 explained that my initial response came across VERY NEGATIVE. I don't see that. I can understand that people might have questions about my early experience, and I can understand that perhaps this question did not fit entirely well in this thread. Okay admitted. But I still think it is a language-thing. I honestly was interested in this new PCB offered/discussed in this thread, but I had a bad experience in the past, so I asked a question about it. That was ALL. Nothing more, nothing less.
But I think that everything that needs to be said, is said about it.
What more can I say? Yes I got confused, and for me it is clear why, to others it is obviously not so understandable that I got confused. Why do I have to defend my confusion? Is there something logical about getting confused; most of the time confusion is not logical duh.
I explained that when people start using the word ORIGINAL in their webshop, it feeds (at least my) confusion that the buyer is buying an original board. I understand -NOW- that it was NOT an original board. That is all. I am not even blaming Dropcheck for this; thanks to all some responses here I start to entirely blame myself. Thanks!
Yes I had a bad experience with Dropcheck previous XF551 boards, other people here perhaps not.
Still I am interested in replacement boards, but I have a certain (fixed) idea what I'm looking for (the 1:1 100% copy, but better quality)
So this time I wanted to be 100% sure that I would not order something that does not match my own (fixed) idea. I did not want to repeat myself getting confused again. I was careful not making my own mistake again. That is why I did ask a question. And then the thread exploded?
And that's all folks.
I think we should move on here.
I wish dropcheck all the luck in the world with her new boards. And I really feel sorry that this thread derailed about this.
