Compaq SLT/286 Floppy Connector Pinout

[KaosEngineer]

As the title mentions, does have the pinout for the floppy connector? It's non-standard and even different than other 26-pin 3.5" floppy pinouts I've found elsewhere.

Pins 1,3,5,7,9,11,13,15 are all ground, and pin 18 and 21 are Vcc (5Vdc). Other 26-pin floppy drives have 1,3,5 Vcc (5Vdc).

Citizen OSDA 53B - discontinued ages ago no info found thus far on any Internet archives

what a couple of us have determined (may be in error) is as follows:

01=GND					02=/STEP
03=GND					04=/WDATA
05=GND					06=/WGATE
07=GND					08=/TRK0
09=GND(no pin)				10=/WPROT
11=GND					12=/RDATA
13=GND					14=/HDSEL
15=GND					16=/DSKCHG
17=/RPM_LC-H/L				18=VCC (5Vdc)
19=/DENSITY_SELECT			20=/INDEX
21=VCC (5Vdc)				22=/DIR
23=???					24=/DRV1 ??? 
25=???					26=/MED1 ???

Drive connector 23-26 connect to a Fujitsu Compaq date code 9014 part number 114390-001 (I think it's a gate array 4x30 pins) QFP chip's pins 13, 2, 3 and 13 respectively.

Thanks for any assistance,

Is it different even compared to the connector found in the large black T-#### series of Toshiba portable computers?
