Want to replace an old 1/2 height 3.5" FDD - need pinouts for the 26 pin connector
Hi there,
I have just acquired an old KAWAI Q-55 Sequencer which has an internal 1/2 height 3.5" FDD and uses 720Kb 2DD diskettes - probably late '80s vintage
It actually works, but since it had not been used for years, the grease in the platter bearing is hardened and it does not spin up reliably ( the belt slips due to the resistance ). The connector cable is 26 pins at approx 1.25 mm pitch.
I have a working Samsung SFD-321S Slimline FDD which is also 26 pins, but much more recent.
Please could anyone provide the pin assignments for the early drive? ( I suspect it may be similar to a Citizen OSDA-53B or earlier )
So what I am hoping is that someone has an old manual with the pinouts for an equivalent FDD. I believe there was an IBM standard for the early 26 pin FDDs.
Once I have some data I can make up a cable to splice the new FDD 1 mm pitch ribbon to the old.
Thanks
