From ZZXIO comes this converter to allow IBM PS/1 and PS/2 computers to use standard floppy drives. These models of IBM computers have the power provided over the 34 pin connector, which will fry a "modern" floppy drive. This adapter routes the power out of the 34 pin connector into a traditional 4-pin Molex connector.
There is a single jumper on the unit that allows pin 4 to either be passed through directly to the drive or to a resistor connected to ground. The default is to directly connect pin 4 to the drive.
This is not for systems/drives with an edge connector. They are available here: https://www.ebay.com/itm/304451554612
Here is a list of models this was confirmed to work on, I will update the list as people provide feedback.
25-286
30-8086
30-286
55 SX
90
L40 SX (original battery won't fit when the adapter is used)
P70 (Use a floppy drive less than 140mm in length with the faceplate removed)
P75 (Use a floppy drive less than 140mm in length with the faceplate removed)

This adapter will not work with systems that require media sense drives. An adapter will be available shortly for these systems.
I offer free returns if the adapter turns out to not be compatible with your system.
