  1. Hi All, I have a non-working Xf551. The head moves out of the diskette window range. The track 0 sensor is working correctly, the problem is in the other size (closer to the center of the diskette). If I ask for a disk formating the head moves nicely step by step from the outside to the inside, but finally start hitting the plastic border of the floppy window. First I thought the track zero sensor was wrongly located "too inside", but even after moving it as far as I can away from the center still the head hits the border close to the center of the diskette. I have little hope regarding this mechanics, but I want to try something else meanwhile I wait for a another d503 or other 360kb drive to show up in ebay with a decent price tag. BTW, I already checked that the xf551 works with another mech. Of my other xf551, so I concluded the problem it is NOT in the xf551 board. Thanks for any help.
  2. After putting together a couple of Dropcheck's XF551 boards, I decided to see if I could make use of the old PCBs and with a little cutting I was able to fit a XF551 pcb and a 3.5 mechanism into a 1050XL case. The back of the case had to have a large rectangular cut out and that is the only bad cosmetic issue. I would like to use the 1050 power switch and power on LED. I have several non-working 1050s so I think I can cut off the pcb section that has the switch and LED; that leaves wiring the front switch as my only real challenge. I would like to know if I could leave the 551 switch in place in the off position and run wires from the power jack through the 1050 switch to the back of the 551 switch.
  3. Remember the idea of creating a 3.5 drive for XL line of computer and devices? I remember that someone posted a 1050 styled kyroflux case. I found it and I guess it can be modified or even used like that as a first prototype. It is a great starting point, but it might need some work to make it SF551 board compatible. As you can see in the link, the kyroflux board goes under the floppy drive itself. Something similar could be done for SF551 as long as the height of the board is not too much. The back openings may need some work as well. I think is will look very cool and usable for large collection of games, images ans some demos. https://www.thingiverse.com/thing:3287420

  5. I have recently gotten my XF551 up and running by replacing the Mitsumi d503 mech. The previous owner had routed around a broken power switch by cutting a trace and jumpering so it's always on. So I have been pulling out the power cord when I want to turn it off and inserting it when I want to turn it on. A pain, but oh well. Recently that power supply died with voltage going close to zero. I have several of these supplies since they're the same as the 1050, but before I start using another one I will ask this question: could the death of this power supply have anything to do with turning the drive on and off by inserting and pulling the plug? Related question - it would be very easy for me to add a generic switch to the jumpered area -- would any 'ol switch work?
  6. The XF551B PCB is a reproduction of the XF551's drive PCB that was sold by 8bitdomain for somewhat limited quantities a few years ago. There's a photo of it here. Failing that, I'll take a whole XF551 drive, working or not. Heck, I'll take just an original XF551 drive PCB (the crappy single-sided one), working or not.
  7. Hi guys, A few weeks ago I ordered a Sio2Sd from Lotharek. Now I am trying to copy an ATR to a floppy disk, but I cannot get it to work. I tried to find answers in the Sio2Sd wiki (the English part) and I searched AtariAge, but I can not find a solution. Hopefully some of you can help. My setup is a 130XE and a XF551 fitted with a XF Speedy. I can succesfully boot from the Sio2SD as drive 1. I can succesfully boot from the XF551 as drive 1, a copy programm recognizes the Sio2Sd as drive 2 but when I start the copy process I get an error 138 on the Sio2SD. It is the same when I swap the drive numbers and when I switch off the speedy part in the XF. But then the really strange part. I disconnected the XF551 to see if the drive is the problem. I use only the Sio2SD as drive one. I can succesfully boot an ATR with Mycopier (got it from this topic: http://atariage.com/forums/topic/206903-transfer-of-atr-images-via-ape-or-prosystem/#entry2667433 ) but when I start the copy process (with the Mycopier.ATR still as the active ATR) I get a read error. So the ATR which succesfully booted cannot be read anymore. The display of the Sio2Sd first displays the following: 31: $3F(?) $0004 and when I hit start again it displays 31: $53(S) $0004. The Sio2Sd is configurated with Highspeed off, Topdrive off, device 0. I have set all unused drivenumbers to off. Any help is appreciated! Best regards, Fred Meijer
