[SOLVED] / EXPLANATION: Got this "faulty" 1050 from a friend and tested with my working disks that I use on some Ataris. When try to load some disks on this "faulty" 1050, I got BOOT ERROR message. First thing that I noticed is that the red led of the disk status on "faulty" 1050 is on for a long time, when cover of disk drive is opened. Comparing with my 1050, the red led from the faulty one is on for a long time and on my working 1050 don't (short duration for me). So, opened the "faulty" 1050, cleaned, pressed the ICs, checked the head with multimeter, assembled the wires and nothing changed about the led. Everything was done before connect the SIO on the Atari and test... So, I turned on the working 1050 with the cover opened and now I recognized the the led is not so bright, very very low intensity, so when compared to the "faulty" 1050 looks like the led behavior is not correct. Then, connected the "faulty" 1050 on the XL, booted and the disks are booting now! Sometimes I have ERROR 144 when using a Disk Application, but I have to replace the belt cause it is dry and do some lubrication. Thanks for all and sorry for the confusion.

When I turn on, the head moves and goes to the start point, but the mechanism still spins for 8 seconds with the read/write led on too. Then stops. Disk Drive disconnected. Only turning it on. I have a fully working 1050 that when you turn on, disconnected from the XL, it only blink fast the read/write led, move the head and stops. I connected this faulty 1050 on XL too and same behavior. No floppy inside on the video. Just turning on the faulty disk drive. IMG_6897.mp4

Just to add information here. Using my working 1050 XL Disk Drive. Using 200 Ohms on resistor scale: 1+3 gives 14.6 2+4 gives 02.6 On the bad 1050 Disk Drive: 1+3 gives 15.6 2+4 gives 02.7 So, the head is working.

Thanks for your reply. On 1+3 and 2+4 the multimeter does the "beep" sound. So, the head is functional?

Hi all. Wanna check if the head of my 1050 are not dead. Which wires on the head cable I can use to check the head with a multimeter? Thanks.

That is the problem. The 1200 XL don't have power for the SDrive-MAX through the pinout or something like that. There is a mod called "SIO 5v Enabled" on the resistor R63, but I can use an external power to use my SDrive. But I did what you suggested. I have 800XL, 65XE and they power the SDrive when the SIOFIX switch is enable.

Mine have, but I know that I have to use an external PSU for the SDrive-MAX to use on Atari 1200XL. It is set to power through the SIO, so I can't use external PSU on that position right? Only moving the switch.

Hi all. I know that post is from some years ago, but just to confirm what I read here. My SDrive-MAX is using SIO to power the device. If I wanna use an external 5v power with P4 connector, I need to switch the SIOFIX switcher for this otherwise it will damage my SDrive? So, the switch how it is, working for SIO power. Switch it to use "only" on P4 power. No way to switch to external power and connect to SIO? It will damage too? Thanks.

Thanks for your reply. The disks are not originals, are copied disks, formatted ones... so think the normal copy tools like Locksmith with mounted file on wDrive can be a good attempt first. Will try. Thanks!

I need to convert my real floppies to a mounted file. Wanna keep my disks on images. Copy from wDrive I did I thinking using locksmith.

Hi all. What is the best way to transfer some real disk to an imagem format like WOZ or DSK or any compatible with floppy emulators? I have a SDiks II and wDrive to use with real drives on Apple. I have a Greaseweazle too, bur never used. Thanks

I asked Best about the complete set, not only the spring. Will try. Thanks!

Hi all. Anyone have to sell this spring for my Atari 800 XL with Mitsumi keyboard? I bought the keycap and plunger, but still is missing the spring. Before I try an alternative way to replace, just looking to buy one. Thanks!

Still looking for this key...

@Darren.gps IOU is still available?

Hi all. Recently I got an Atari Lynx model PAG-0201 that is not turning on. I will do the recap and check everything but it came with a bad trimmer. The VR1 50K Trimmer is cracked from the previously owner and need to be replaced. Anyone knows where can I find a new one or old one to replace? Here are the pics! Thanks.

What is your point?

Maybe I can get a not so rare, cut inside and try to do something on my 3d Printer as a plunger.

Thanks for your reply but this models, and the below too, are not Mitsumi compatible

Help an Atari, please!

Hi all. I'm looking for a spare part key complete set for my Atari 800 XL. I need the DELETE key for a Mitsumi keyboard model. Need the keycap, the plastic plunger and the spring. Need too the metal plate from the function key for other XL but this can be from any model as I just need the metal cap. I have the plastic keycap without the metal part. Anyone can help me?? This are the pictures of my 800 XL. Thanks!

Thanks! I will try

I use other Intellivision with same board to test the ICs from mine.

And no idea of which eprom I can use?

Hi all. Is possible to use an EPROM and burn/programming as the GROM or only get an original IC? Thanks.
