  • Re: 186-050 IBM 4865 PERSONAL COMPUTER 3.5" EXTERNAL DISKETTE DRIVE MOD

    From Louis Ohland@21:1/5 to Louis Ohland on Sat Aug 5 11:49:44 2023
    Both use split power / signal, the Model 1 uses the existing 5150, 5155,
    or 5160 floppy controller and the Model 2 has another adapter that goes
    into the 5170.


    o 4865 Model 1
    The 4865 model 1 has a permanently attached 36"
    signal/power cable that attaches directly to the existing 5.25"
    diskette drive adapter on the 5150, 5155, or 5160 system unit. A
    customer installable power split cable provided with the 4865
    makes system power available to the 4865. For the IBM Portable
    Personal Computer, a slot is required to install the external
    power supply connector. One 4865 can be attached to a system
    unit.

    o 4865 Model 2
    The 4865 model 2 has a special external diskette drive
    adapter card that is installed in expansion slot 6 or 7 of the
    5170 system unit. This card connects to an existing combination
    fixed disk/diskette drive adapter. Connection is via a
    permanently attached 36" single/power cable on the 4865. A power
    split cable provided with the 4865 provides system power to the
    external diskette drive adapter card. One 4865 can be attached to
    a system unit.

    The 4865 was also used with models of the Wheelwriter typewriter - and with a power source, it probably could be used with the Diskette Adapter/A as well.

    It can´ t be used in any of my PS/2 so I sold mine to USA few days ago. Didn´t knew which model 1 or 2 it was. It has only 37 pin cable with no power.
