I have a 6128 and a spare internal 3" drive. Is there a way to connect it externally as drive B? What kind of cable is needed to create?
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
? what is the model number of the Drive :- EME-XXX
Ray
EME-156
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
In the wiki there is some wiring detail of how to connect a drive 34 Pin to 26 Pin.
The drive has to be modified as per photo to be Drive B.
The LINKS on the Photo is ONLY for the " ME56PB31 " MOTHERBOARD (EME156)

** please make sure the Power Voltages are in the correct pins (4pin connector)
Good luck
Ray
Thank you for the info.
What do you mean by "correct pins"? I will be using an external power supply.
@vasilisk
The 4 Pin connector on the emeXXX is not wired as the industry standard.
The +12 and the +5 are reversed.
Please be careful.
Thanks. Ray

CORRECTION

Please check
Thanks. Ray
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
Can you send a Photo of the Motherboard Please
Thanks. Ray
I am at work now. I only have a partial picture. I can send a complete one when i return.
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
Ok Thats good. The link is under the board, remove it and wire up as per photo.
Ray
For education purposes, why is this needed?
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
If you leave the original link connected and add the new one then the drive becomes A AND B ?
we only require it to be Drive B for this project.

Why would that matter when only the Drive B: select goes to the external drive? The drive inside an FD-1 certainly doesn't need this mod.

@Bryce (http://www.cpcwiki.eu/forum/index.php?action=profile;u=225)
I have made up 2 external test leads to check 3" Drives.
One for Drive Select 1 (A) and an other for Drive select 2 (B)
and if you don't use the link the B Drive does not get selected ?
Ps :- Both Drive Selects are connected on my 6128 ?
Ray
Ok, interesting. Must check inside the FD-1 to see if one gets disconnected inside. I'd recommend making the change to the cable rather than modifying the drive. That way any 3in drive could be used and they can be swapped back and forth.
Bryce.
All
The leads I have made up :-
I use the Converted (eme156) "B" drive on an old PC to create 3" disks.
Ray
If we can make the modification in the cable and not in the drive itself, is preferable.
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
Make a cable up using the second and fourth photo.
That can be used for a standard drive to be Drive B
Ray
Thank you. in the second photo, if i see correctly, the sixth cable goes to the fourth pin. The fourth and the fifth cable where do they go? both in the fifth pin?
The Fourth wire is not connected
the Fifth wire goes to slot 5
the Sixth wire goes to slot 4
Good luck. Ray
What are the differences between the two cables in first picture?
I made the upper cable, and the drive B led is always on and the motor keeps running. Should I made the other cable instead?
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
For Drive A External
Use the Photo "For %22a%22 Drive"
The one with the twist at Slot 4- 5
The 4th Wire is Not connected.
The 5th Wire goes to slot 5 On the 26 Pin connector
The 6th Wire goes to slot 4 On the 26 Pin connector
Check the other end (34) is wired as per Photo "Other end"
Leave the 2 slots empty and move the last 6 wires over 2 slots towards 34
Check that the Red stripe is near the keyway in the Connector.
If you don't have a 34 connector with key the maybe its upside down ?
Ray
Thank you. I want Drive B to be external. Drive A is internal.
Is the cable in the photos made correctly?
Photo IMG_20191008_004725.jpg (http://www.cpcwiki.eu/forum/technical-support/connecting-an-internal-3'-drive-as-external-b/?action=dlattach;attach=29706) looks a bit Odd
The red stripe should be in the first slot ?
It looks like its in the wrong slot ?
therefore the rest are also incorrect ? ? ?
My reference to Drive A Is that the drive is configured as Drive A (No link change)
Ray
@vasilisk (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2004)
A Better photo of the 34 Pin end
Ray
Ok. I remade the 34 edge connector.
The 26pin how do I connect it to the dive? the red cable goes from the side of the power or from the side of the motor.

Is there a modification to the cable needed afterall?

Not making this cable but is fun to watch.
Question:
On mobo's edge, pin 12(bottom) says it's Drive 1.
In which pin of the drive does this go?

Ok. With these connections, internal drive A is working, and external drive B produces "Drive B: Disc Missing" when we execute "cat".

Put the drive that you are testing inside the 6128 and see if it works ? ?
Please check your wiring on the 26 Pin.
? IMPORTANT Check the Power Lead ? ? ?
Photos below
The Large connector is PC Standard. The small one is ONLY for the 3" drive ONLY
I cannot help any further.

This is the first think I did, just to make sure. Drive is working perfectly.
Are you sure this cable works WITHOUT any modification to the drive?
Thanks again for your help.

Yes I use this Cable to test (UnModified) Questionable drives, I have an other cable to test drives set for "Drive B" also
Please check the wiring of the 26 Pin end of cable.
Please put the test drive back in the 6128 and see if it works. Again
Ray
I have two working drives and I have tried them both. I will try and make again the cable. The "other" cable you mentioned, what is it?
Finally, the cable worked. The culprit was the egde connector. The position of the cable was not letting the connector to "touch" all the "pins" from the Drive B port. I had to improvise by lifting the keyboard. Thank you audronic for the creation of the cable.

Hi vasilisk
Well done
The other cable is different is has No twists at the 26 Pin Connector end.
Good luck
