Which Gotek Emulator?

[pioneerfreq]

Greetings,

I am trying to replace a 1.44MB Epson SMD-1040-318-01 floppy drive in an HP54542c Digital Storage Oscilloscope. The floppy drive has a 34 pin IDC connector without additional power connector. I cannot find the pinout details of this floppy drive but the HP54542c Digital Storage Oscilloscope uses a DP8473 floppy controller chip so I was able to find the floppy connector pinouts:

Function: HP54542c Floppy Connector Pinout
DISK CHANGE: 2
INDEX: 8
DRIVE SELECT 0: 10
DRIVE SELECT 1: 12
MOTOR 0: 16
DIRECTION: 18
STEP: 20
WRITE DATA: 22
WRITE ENABLE: 24
TRACK 0: 26
WRITE PROTECT: 28
READ DATA: 30
HEAD SELECT: 32
GROUND: 13,15,17,19,21,23,25,27,29,31,33
+5V: 7,9,11

Really need help trying to find out which Gotek would be appropriate.

MANY THANKS!!!

Hello,

For as far as I know the only differences exists with the floppy connector. 34 pins IDC or Edge connector.
The other variations are based on processor, PCB design or firmware.

I am only selling the SFR1M44-U100LQD 435 OLED Gotek. They can be attached to almost everything with the HxC firmware.

For your situation I would use this version. I would split out your ribbon cable to detach pin 7, 9 and 11 from the IDC connector and connect it to a power connector. There is no need to split the ground as well since the ground is internally connected between the odd numbers of de IDC and the ground of the power connector.
