I finally finished one of the bare boards. It almost works perfectly. I can only get it to work as drive 1 or drive 2. When I first tested it, it would only work as drive 1 so I must have a bad selector switch or a bad solder joint on the selector switch installation. Going to have to look at it with a magnifying glass.

I am trying to find Atari enthusiasts in the vicinity of Raleigh NC

I was actually asking about pictures of the mod; which you have provided. Thanks. I can't imagine why the sony doesn't work because the slider switch is clearly designed to set the drive number.

I assume you are referring to the pins of the 34 pin connector. Do you have pictures?

I am using the cable that is original to the PCB with a card edge adapter. The cable works with the 5.25 drives. I am going to cease working on this thing until I find a supposedly compatible drive.

The Sony that I have does have a 4 Pin power cable it also has a slider switch to select d0,d1,d2,d3. It still doesn't work.

Thanks for the info and the link, maybe that is why I am running around in circles.

I have a Sony MFD-11W-41, a TEAC FD-235HG, and a NEC FD1231T. I am hoping that the problem is with my cable. I just ordered an adaptor so I can change from the card edge connector to the female 34 pin connector. I know the current card edge connector is working on my 5.25 drive.

When everything works correctly, can the 3.5 drive be used as drive 1-4 by changing the 551 drive dip switch?

The board works with a 5.25 using the hyper a rom yes.The cable I am using has the connector for either size floppy. I don't know about the drive settings because I really don't know what I am looking for.

Should the 3.5 drive work with any DOS or does it have to be a specific DOS like SPARTADOS? I have done everything that the instructions say to do and I am using the HYPEROM B, I have tried 3 different 3.5 drives and none of them will work. The drives come on and spin up, the computer gives a few beeps and then I get an error 144 or error 163.

I hope the RF shield on the 1200XL is optional. I just finished installing the U1MB on mine and I couldn't possibly fit the shield back on. I also have a UAV-D installed and I would have to make a cutout just for that.

SF314 disk drive, I'm hoping to convert it to work with 8-bits using one of the new boards from BitsofthePast.

I wonder about the cable because it is a homebrew. I may go pack and recheck the PCB with a 5.25 I am leary of doing much with the PCB because of its inherent fragility.

When I used the PCB with a 5.25 I had the stock IC (101696??)and a WD1772.

I have two 3.5 drive mechs that I have tried connect to a XF551 PCB. One of the mechs has a slider switch on the side the other has nothing that I can see, when the slider is set to 0 and the PCB switch is set to drive 2, the drive seems to be attempting to respond. If I attempt to read or format the 3.5, it spins up makes some slow beeps and eventually gives an error 144. The disk is not HD. The only thing I can think that might be a problem is the flat cable. The PCB worked with a 5.25 drive and I am using a hyper version B chip. Looking for suggestions. Both mechs exip the same behavior.

I had a typo error the labels are ds0 and ds1. DS1 appears to be connected.

The drive will not read a disk nor can it be formatted. It appears to be trying to read and format otherwise.

I have been trying to figure out how my 3.5 drive is set and I found three solder points in triangle arrangement two are labeled DS1 & DS2; there is a connector between DS1 and unlabeled point. Is the likely jumper that needs to be changed?

I want to find Omniview XL/XE so I can flash it to a U1MB drive where do I go?

I was obviously on the wrong website, I was here http://a8preservation.com!.What is the link to the archived files?

How do I download a file from the preserved software list to a SD or micro SD?

When the 1050 is drive 1 and the 3.5 is drive 2,the 1050 works perfectly. I boot MYDOS 4.3 then I try to read the directory of D2. The 3.5 spins makes some slow beeps as if the drive is trying to read a disk. After several seconds I get ERROR 144. The same thing happens when I attempt to format D2. I am not using a new board, I wanted to make sure I had a good 3.5 before I tried it on a new board. Tomorrow I plan to open up my PC and see if there is a way to hook up a 3.5. If so I could maybe test the 3.5.

If the switch on the 3.5 is set to anything other that zero, the drive does not respond at all and the disk never spins up and the light does not come on except briefly at power on.

This drive has a 4 position switch on the side that shows a 0 on one end and a 3 on the other. I would suspect that it could be assigned as drive 1-4 or 0-3. When I place the switch in position 0 and set the Atari switch to drive 1. The drive attempts to boot and says BOOT?err16 on the screen. If I set the Atari switch to drive2, and a 5.25 drive as drive 1 when I attempt to read the directory or to format the disk, I get a few slow beeps for several seconds and then error 144.
