34-pin floppy disk adapter for IBM PS/1 and PS/2

Description

This converter allows 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 Berg 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.

Here is a list of models this was confirmed to work on, I will update the list as people provide feedback.
25-286
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)
Reply TurboBoard 60/65/80
TeraDrive

This adapter will not work with systems that require media sense drives.
