? I don't have enough info for diagnose 30 years old hardware in USA specially on distanse.   Sorry i'm not doctor House .  ;D For miracles you must go to church not to me.

FD1 drive unit  working with other floppy interface  (orginal DDI1) and your CPC 464  ? Format, read your floppy discs?

Here you go:

Hope you can solve this is a constructive manner rather than... well all of this above...

The cable is in the pictures above. No cut out leads, one-on-one.
Also, works with HxC. Does not work with single FD-1 connected.
Why does the drive access light flicker??? You can also tell that the motor spins on and off. So the cable is ok.
I also tried other cables, same effect. Disc missing after motor spins up.

It seems you are assuming that a second drive is present in the chain, doing something to the READY signal or whatever.
No clue what.

See the video for proof that this drive and disc are fine... with original DD1.

Not at all. Just trying to get something working here....

As I said, there is no technical support from me until you close paypal. You have chosen the legal path yourself when you do a claim . Now, lawyers have a job.
I can help, but not on this way. Sorry.

So you are saying you know what the problem is, looking at the video above? And you are willing to share that information (publicly) if I am going to close the case?

LambdaMikel

Tested with second FD-1, same effect:

So, for your understanding of the nature of the PayPal claim:

       
  • I didn't receive the cable which should have been part of the auction
  • I made my own cable
  • The action claims that DDI-4 works with FD-1.
For me, it doesn't, and I don't know why.
After waiting for a couple of days for Piotr's anwers, I filed the claim, with the checkbox "Item doesn't work as described".
That's fair I think.


I'll close the claim as soon as the FD-1 starts working.


Piotr

As i say, i escalate Paypal claim , please return interface , is not for you.

Immature... 


If anybody has a working single FD1 config with DDI4 please be more  mature and speak up.

LambdaMikel

Do you want me to publish a review for DDI4 on SellMyRetro?
I still haven't rated the auction yet...

So it seems it is defect somehow. Please provide a shipping label and I will.
Or save yourself the costs and tell me what cable mod is required for the FD-1 to make it work.
Whatever you choose.

I'll not close the case either this is resolved in one way or the other.

it looks likethere is a capacitor stuck in some pair of pins in the second connector.?

So, I was on the right track... the ABBA switch doesn't work.

The cable modification that Piotr was trying to hide in his video is this one:
http://www.cpcwiki.eu/index.php/Guide_on_how_to_connect_a_3.5%22_drive_to_a_CPC6128/664


One needs to connect PIN 11 and 12 in order to make it work. And then, A / B selection doesn't work at all.Without the bridge between 11 and 12, one gets "disc missing".

Here is the video:

https://youtu.be/rgl4hPBMDAc
I must say I find Piotr's behavior shameful... one can clearly see that he has a jumper / bridge between 11 and 12, yet he says it is a standard cable without mods. I am really angry about that. I won't buy anything again from him with this immature behavior. What's worse, he is calling me the morron that doesn't know how to use his great piece of hardware. Even though I am one of his best customers who bought 5 CPC extension from him by now, he ignores all customer support inquiries for days, and the only means of making him reply is filing a PayPal case. Yet, then he gets all pissy about what is considered a normal mode of operation (disputes are there to be resolved!!), and acts like the soup nazi ("no DDI4 for you!") See video.

I am wondering what others think of that. I am not a fan of excluding people from the board, but I must say I find his behavior hard to tolerate.

Either he should own that his DDI4 has a bug, or that mine is defect. In any case I am expecting some kind of solution. I am not closing the case until I hear from him publicly with some kind of explanatino what's going on.

Right, I forgot - "now laywers have a job" - well we will see about this  :laugh: :picard2:

It's the same with his internal 3" Gotek drive. You need a modification to use it with an external 2nd drive.


(discription for this modificatation you find here ...)




It' s a shame...

Thanks, I actually applied that mod to my Saxdrive already. I only got my Saxdrive last fall and I was disappointed that he had not changed the hardware, given that this was a know problem for over 2 years by then. Very few customers actually seem to use a 2nd drive, so it doesn't seem to matter that much for him. Also, the Saxdrive works as a primary drive without mod, not problem. With the DDI-4, the main problem really is that is DOES NOT WORK AT ALL with 75 % of the configurations without mods. THat mean, FD-1 doesn't work out of the box, and neither does standard 3.5" floppy, if floppy does not have READY signal. Now, that's not his fault, it IS his fault though that the standard READY HACK for the cable DOES NOT WORK with DDI-4, since GND is missing (one has to route another cable to PIN 1). All this in order to give people an incentive to buy his dual drive? Who knows.

I though that would be different for DDI-4 though, as this is really only a controller + RAM (it does not contain a Gotek, unlike Saxdrive). So it should not be necessary, right? Anyhow, at least I didn't expect it. I will have a look at the Saxdrive mod and see what it does if applied to the DDI-4. In the meantime, with the cable  bridge / jumper, it is working, I only need to figure out how to also have the HxC as second drive. But should be possible now. Thanks anyways!

This is to confirm that a properly RDY-signal modified SINGLE Mistumi D359T5 works without problems with DDI-4. No cable mods required, and AB switch works as well.

Of course, this only applies for one drive. As soon as FD1 is present, problems occur again, see above. But we now know how to fix it.

Piotr

? Yes, floppy drives need mod. Ewerybody know.

Anyway, this cowboy ask me about refund before. I do it via Paypal.Lot of problems but is done.

Today this cowboy LambdaMikel  send me via paypal  50 GBP as donation ? WTF?  I send it back. With all respect, LambdaMikel  ?

Neither fd1 nor cable should need a mod to work with ddi4... That's not the case unortunately.
And you didn't tell us...
At least try to minimize customer frustration by writing a line or two about this on the ddi4 auction page.


I never asked for refund. I asked for a return and customer support.
But you wouldn't answer and then you refused to help.
After a lot of trial and error I figured out how to use fd1 with ddi4.

I have received a DDI-4 to use wih a CPC464 + FD1 for a friend. The overall quality look good.
I hope to not have any issue plugging it, else this hardware will be useless compared to a DDI-1 with embedded X-MEM.

Well, keep us posted if you are encountering the same issues as I did. Maybe mine was an early prototype or has another defect resulting in it requiring mods. If yours behaves like this as well, you at least have an idea how to mod the cable and such that you can keep going. 

I am curious to learn if a simple 34 pin floppy cable to FD1 (no second drive present) works for you out of the box, or results in "disc missing" after motor spin up (regardless of ABBA switch position). If so, you simply might have to bridge PIN 11 and PIN 12 in the cable (see my video above). That fixed it for me.


Also, did yours come with a cable? Mine didn't. If so, please post pictures of the cable or describe any mods applied to it.

TotO

I will let you know next week, because I'm currently not at home.
If I remember well, the DDI-1 had an embeded ribbon cable, not the FD-1. So, I expect to use a pin compatible cable to do work.

Correct, you can just use a standard 34 PIN untwisted PC floppy cable. In order to fit into the FD1 socket, you will have to cut off the "locking pins" from the IDC connector (otherwise it doesn't fit physically into the FD1 socket).
