sio "y" cable

Recommended Posts

is it possible to make? I thought it would easy enough to hack 2 cables. one half of a cable was used for my apelink. so i thought i could just slice another cable and solder the other half into it. Needless to say, it didnt work. I hooked one end up to the computer, the other end to a disk drive and the other end to an 850. The first drive worked, anything coming out the 850 didnt.

Have to make sure your Data In and Data Out are connected correctly...

 

and unless you are going to be using SIO powered devices, pins 3, 4, 5, 7 are all you need to connect... (Data In, GND, Data Out, /Command)

 

and be CAREFUL with pin 10... It has power on it...

 

 

sloopy.

i may have criss crossed a wire or something. I took 2 cables that had the atari logo on them (i think) so i was under the assumption that the wires were the same. I basically soldered all wires together. Ill dig a little deeper on the end and take another look.

 

thanks

then swap the conns... take the SIO out of the A8 and the 1050, and swap them... and it should work...

 

sloopy.

Wich such a cable I could use Aspeqt and my new DRive together? How would the drive numbers be assigned? Is it enough to use drives 5-8 in Aspeqt?

Device numbers have nothing to do with cabling, they're assigned at the device.

 

Ape/Aspeqt lets you assign any of D1-D8 so it's up to you to decide what any real drive has, but most only do D1-D4.

As long as it's correctly wired (1:1) it works. Did the same years ago.,

 

 

The first drive worked, anything coming out the 850 didnt.

 

My experience is that an 850 (at least the ones I have) is a big load on the SIO bus compared to a 1010/1050. With a single chain I can connect 7 or 8 disk drives without problems but when an 850 is part of the chain only up to 3 disk drives work reliable.

 

However I'm in doubt this applies to your case, just keep it in mind :-)

I think a 3-way SIO port adapter (like the Quintopus but 8 are not necessary anymore) would be a nice project. I wish Atarimax would make. He has his own source of white SIO ports and it would be great for all the users of dead-end SD card drives.

 

Maybe no market. I put the Sdrive/SIO2SD after the 850 to use the printer. I use 1010 in-line for cassette. For SIO2PC, I use PC printer. Now he sells SIO2PC with daisy chain port, too.

Hello guys

 

Check out the Automatic Two-Computer Interface, by the guys who made the SIO2USB (to USB devices, not SIO2PCviaUSB). It works with everything, but SIO2USB (the latter uses the clock signal, which the A2CI doesn't pass along).

You can get a Eas I/O spider which has SIO ports for CPU and 3 peripherals from Rick at MorethanGames.

Or the Apelink from Best Electronics, they are the same thing, except Apelink is a kit you have to put together. I think the spider you can buy complete or in kit form?

 

19Echo already has the Apelink, but during it's construction he ended up with half an SIO cord with the configuration he chose, so he's doing the 'Y' cable to make use of the other half and essentially regain the lost cable used in the Apelink construction.

The SIO Y cable is definitely doable. I have one that was a 3rd party cable from back in the day and it works great, especially when using 1 for your drive chain and one for a piece of hardware without a passthru.

I found this article from the newsgroups:

 

<quote name='newsgroups'>

 

Paul Alhart who published a neat and cheap alternative in

AIM magazine way back when. You lay two SIO cables side by side and

strip about a foot of cover off each one, starting about 8 inches from

the paired ends, uncovering towards the center. You then bunch the

foot of uncovered wire together so as to expose/create a large ball of

wires on each cable. You then find and combine each color of wire with

a few tight twists. Then at each twist, you apply a soldering iron to

melt away the insulation, apply some flux and then solder the same

colored wires together. Make these connections all along the way of

the bared one foot of wire such that no connection can touch any other.

Tape each connection with electrical tape, then tape the whole bundle

leaving out the ground wires. I cut the ground wires in the middle and

fold them back to then wrap the main portion with aluminum foil and

integrate the ground wires into the foil on top and soldered back

together followed up with a good wrapping of tape.

 

You can't beat the price or availablity. The utility of such a four

headed cable will amaze you once it's built. Use the two short ends (8

inches) for your disk drives with the long ones used for your computer

and Atari printer. You now have three open ports to link everything

else with.

 

The only problem is when the color of the wires are not the same, I

never ran into that situation though. Chances are good they will be

matched which is something you should double check before soldering the

first wire?

 

I was in need of just such a critter when I got that AIM issue, thanks

Paul, you saved the day. It's a bit more work than it sounds, but it's

well worth doing.

That AIM article was what I read and made a Y cable for back in the early 90's. I just couldn't rmember where I read the article. Though I thought I looked through all my AIM magazines for it without any luck, but maybe I'm missing the one with the article...I'll look again. Do you know which issue it was in? Oh, never mind, I see you were quoting someone else and those arn't your words...
