Kyle22 Posted May 9, 2015 Share Posted May 9, 2015 The drive may work if you can jumper it as drive 0 instead of 1. It has a lesser chance of working as drive 1, which would be seen by the ATR (and the Atari) as B: or D2: Having said that, I don't remember if you can have drives on the ATR that don't start with 0. In other words, a 1050 or similar as D1:, and the ATR drive(s) as D2: (D3: D4:...) The cable is definitely wrong. You need a straight thru NON TWIST cable for the drives. 34 pin edge connectors (or pin sockets for 3.5") the whole way around. The ATR is very flexible, if you have the proper drives and cabling. You can even use 1.2M 5.25 HD drives, and the ATR (and SpartaDOS) will consider them to be 77 track DSDD 8" drives. Here is the manual for the ATR-8000: http://www.ftp.pigwa.net/stuff/collections/SIO2SD_DVD/Instrukcje/ATR8000/atr8000.pdf Quote Link to comment Share on other sites More sharing options...
Wally1 Posted May 9, 2015 Author Share Posted May 9, 2015 thanks how about this cable http://www.ebay.com/itm/36-Universal-34-Pin-Floppy-Drive-Ribbon-Cable-for-3-5-or-5-25in-Drives-FF-002-/390551711664?pt=LH_DefaultDomain_0&hash=item5aeeb22fb0 and can you explain more about this in general thanks Quote Link to comment Share on other sites More sharing options...
sup8pdct Posted May 9, 2015 Share Posted May 9, 2015 No. you will need to find a cable without the twist in the middle. It may be possible to remove the twist by pulling off the small plastic parts that cover the cable, carefully remove the twist part and put it back. It is easy enough to roll your own tho. just need the right tool to crimp the cable on to the connector. I have used a vice in the past, pliers, my body weight and door jams..

sup8pdct Posted May 9, 2015 Share Posted May 9, 2015 One end has wrong connector you need card edge to holes. James Quote Link to comment Share on other sites More sharing options...
fujidude Posted May 9, 2015 Share Posted May 9, 2015 (edited) The twist in the cable simply changes the drive ID so that you can plug two drives on the cable that are both set the same, yet one will be seen as drive 0, and the other as drive 1. Let me drag out an old reference book for the detail... Okay, this was something IBM did as a modification to the Shugart SA400 interface. Anyway the twist cable is designed to work with IBM style floppy interfaces, not 100% Shugart complient ones. Two floppies can have their drive select both set to DS1 (drive B), and the drive connected after the twist will be seen as DS0 (drive A). The ATR8000 is likely Shugart standard rather than the IBM way (which more or less became a new standard). So you should be able to use a twist cable, so long as you only use the plug prior to the twist, and set the drive as DS0 (A:).

Wally1 Posted May 9, 2015 Author Share Posted May 9, 2015 i hate to keep doing this but http://www.ebay.com/itm/Floppy-Cable-Card-Interface-Universal-/291431014549?pt=LH_DefaultDomain_0&hash=item43daa46095 this one seems coool right Quote Link to comment Share on other sites More sharing options...
sup8pdct Posted May 9, 2015 Share Posted May 9, 2015 there is a fold in the cable between 2nd and 3rd connector which i suspect hides the twist. the part you want is from the 3rd connector from left to the right hand end. If you get that cable, get a sharp knife and cut the cable flush with the 3rd connector from the left on the left hand side. Knife MUST be sharp.. That way, you wont use the twist part and not have unused ends that could cause problems due to stray capacitance James. Quote Link to comment Share on other sites More sharing options...
ACML Posted May 9, 2015 Share Posted May 9, 2015 If I can remember my ATR-8000 days I had to make my own cables. 1) they must be 34 pin ribbon cable 2) the ATR side has to be a card edge connector, not pins 3) no twist between drives 1-4 (yes, you can have four drives) 4) I think the last drive needs a resister terminal block (on drive PCB). a 1.2MB 5.25 can be formatted as a 8" 77 track on MYDOS giving it ~1MB of space. the ATR-8000 writes 360K DSDD like industry standards, so it is not compatible with a DSDD XF551.

fujidude Posted May 9, 2015 Share Posted May 9, 2015 (edited) You can get pin to card edge adapters (or at least you could). Think I may still have one or two in a drawer. Okay I do but they are not what would be needed here. Mine are femail pin to male card edge. Edited May 9, 2015 by fujidude Quote Link to comment Share on other sites More sharing options...

I suspected it was faulty but I now think it was actually a duff 1.44MB drive I had bought off ebay. Maybe I will hang on to it after all! If I hadn't just mortgaged my soul to buy the "Ultimate1mb" and all its fascinating pals from old Lotharek I would be scouring the different ebays trying to find an ATR-8000. I really want one now... I think it would satisfy all my immoral floppy-drive urges in one go... Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted May 9, 2015 Share Posted May 9, 2015 And, since the Indus-GT and the ATR-8000 both have Z80's, I wonder how difficult it would be to transplant the Indus high speed code from SDX into the ATR... The lack of high speed SIO is the only thing that puts me off about the ATR. They're both bit-bangers, so it's all done by cycle counting. No UART programming involved. A person would need well commented source code and memory / I/O maps for both devices side by side. Quote Link to comment Share on other sites More sharing options...

morelenmir Posted May 9, 2015 Share Posted May 9, 2015 As a matter of interest I got the cable attached to what was then a brand-spanking new Pentium 100 PC in November 1995. I bought the thing from a nearby private computer store for what I later discovered was an obscenely inflated price over the cost of parts and even a fair labour charge... Teach me to buy local, idiot that I was (arguably am)!!! Actually, to be fair it did just that as I have always bought components and put them together myself ever since. Anyway this is relevant because as I say it was a small, local PC shop that catered mostly to business customers - which partially explains the massive mark-up I suffered. I dare say it was just a cable they themselves had kicking around from the early-nineties if not prior still. Quite possibly from exactly the same time the ATR-8000 was first available; certainly from the period where it's type of floppy drive were common enough to be given special plugs on the IO cables. I have never really understood those edge-connectors before seeing your post earlier Wally1 - so many thanks for it! I'm glad I read it before the thing was taken to the tip.

As stated in the description it has no power connector, they are routed through the 34 pin cable. This leads me to believe it is a Tandy type drive although I think there was more then one manufacturer that did it that way. Completely incompatible with an ATR8000 anyway. Editorial comment that is not meant to reflect on you: 720k floppies are stupid expensive. The cable will work, just not real conveniently. See how the last two connectors have a twist? Just cut them off and use what is left to plug into the ATR8000 and your 720k. Worse case is you may have to pull one of the connectors off and put it on the other side i.e. go from === === xx= xx= === === to xx=== xx=== xx= xx= === === x=> air, had to put them in to make the spacing right. Get what I am saying? The end that would normally plug into the motherboard/fd controller, you plug into your drive. The card edge connector that you would normally plug into a 5.25" drive, you plug into the back of the ATR8000. IMHO, you would be better off making sure the drive you buy has the jumpers people are talking about on the drive. It isn't a show stopper if it doesn't, just make it a bit more difficult if you want to boot from the drive. Standard IBM type drives are sometimes soldered in place to look like the second drive.

+Larry Posted May 10, 2015 Share Posted May 10, 2015 Do you have a regular SIO drive? That is certainly the easiest way to get this going. If you want a 720K, drive do you have any issue with using a 1.44? I'm sure you would find zero difference in usage, so long as you are using 720K disks. I have an ATR 8000 and quite a few 720K and 1.44 drives and cables. If you would be interested in getting a "turnkey" system that works, send me a PM. I even have bunches of 720K disks. -Larry Quote Link to comment Share on other sites More sharing options...
