Need a cable for an 8" floppy drive. Edge connector at one end and dual row pin header at the other end. 1 or 2 positions will work, length doesn't matter too much - ideally 2-3' since its for self-contained enclosure. Let me know if you have a spare you'd part with. Thanks!

With one of these crimpers you can make your own. I find them incredibly useful. https://www.ebay.com/itm/121434221114
Youd need Ribbon, like this for example: https://www.amazon.com/Connectors-P...+conductor+wire+flat+ribbon+idc,aps,53&sr=8-1
Just find the best parts for your price. Just a thought if no takers.

Are they male/female pin header or edge connector? I have several 8" drives but havent worked on them yet. All inside thier perspective machines.

Just lookup 50 connector IDC edge and go through the listings

The connectors will most likely be the most expensive part.. Around $5.00 each at least.

Just curious. I was going to get into 8" floppy production. How do you intend to power the unit (which are all AC power I believe) by the computer chassis or are you adding your own power?
Perfect.. and if I want to make it a 2-position cable, 8" drive don't require a twist right? and drive position on the cable doesn't matter since it's driven by Drive Select (DS 1-4) at the drive level, correct?

With the 8" drive I honestly cant confirm that. Youd need to get that from someone more in the know. I thought drive select was done on the drive mechanism.
Oh, if so - can I be your first customer? I still have no idea how I'm going to bootstrap this machine (or whether it's even possible) to format and create a CP/M disk. The chassis I'm using has 2 power supplies for 8" drives built into it. It's a cool chassis, unfortunately it's missing the cover so I may look for a new home for it if I can find another S100 chassis with room for at least 1 8" drive inside.
Here's the power supply. Note the 2 upright PCB's. Those take the DC output from the caps and coverts it to 24V & 5V on the 6-pin power connectors. It also takes a 120VAC lead. So my drive requires both DC & AC.

My method doesnt seem to difficult. Watching Petes video here:
I bought the Dbit 34 pin to 50 pin adapter. And I intend to connect the 34pin ribbon to a Dos machine and run Dave dunfields imagedisk to control and operate the 8" drive and create, copy, and make disk images to actual disks.
I have a TRS-80 model II, IBM 5120, and MAI basic four mini computer. All have 8" floppy drives. This is one of my many back burner projects... I have so many.

Very cool, let me know how this works out! I already have a DOS machine I use for imaging (5.25" 360k drive, 5.25" 1.2 MB drive + 3.5" 1.44MB drive) - would be very cool to add an 8" to that setup.
