Apple drives Emulation support
Last modified: 03 March 2024
The HxC Firmware is the first firmware for Gotek supporting Apple II disk drives floppy emulation since the version 5.1.1.1a.
Note
|
Read & sector write operations supported since the version 5.2.1.1a. |
Youtube demo : https://www.youtube.com/watch?v=B-pzItOAO1g
AnotherMaker’s test/review : https://www.youtube.com/watch?v=NI3qG2vm8Fg
To use it, update the Gotek with the HxC Floppy Emulator Apple II firmware present in the "Firmwares_Updates/Generic_Gotek/AppleII_Firmware" folder in the firmware archive. (See Firmware update)

The Floppy Emulator Apple II pinout assignation is :
Apple II floppy interface <------------------> Gotek floppy interface
(Internal 20pins / Ext DB-19)
PH0 (Int pin 2 / DB19 pin 11) <------------------> UART RX Pin (J4)
PH1 (Int pin 4 / DB19 pin 12) <------------------> UART TX Pin
PH2 (Int pin 6 / DB19 pin 13) <------------------> /DIR (18)
PH3 (Int pin 8 / DB19 pin 14) <------------------> /STEP (20)
/WREQ (Int pin 10 / DB19 pin 15) <------------------> /WGATE (24)
SEL (Int pin 12 / DB19 pin 16) <------------------> /SIDE1 (32)
/DRVEN (Int pin 14 / DB19 pin 17 or pin 9 *) <-------> /DS0 (10)
RD (Int pin 16 / DB19 pin 18) <------------------> /RDATA (30)
WR (Int pin 18 / DB19 pin 19) <------------------> /WDATA (22)
WRPROT (Int pin 20 / DB19 pin 10) <------------------> /WPT (28)
Power :
VSS/GND (Int pins 1,3,5,7 /
DB19 pins 1,2,3 ) <---------> Gotek VSS power input (Power pins 2, 3) +
Gotek floppy interfaces pins 33, 27, 23, 21.
+5V (Int pin 11 / DB19 pin 6) <---------> Gotek +5V power input (Power pin 1).
The jumper must be set to "S0".
Note
|
Some simple adapters are now available to connect the Gotek to the Apple II very easily. See the AnotherMaker’s video for example. |
Note
|
For SFRKC30.AT2 Goteks with the small QFN32 AT32F415 : The Rotary select switch is connected to the RX serial line, so to avoid this conflict, you need to disable the "Extra Select button" option, set the "Apple II emulation mode" option and generate a new firmware from this page : https://hxc2001.com/custom_fw/ |
The Apple II .do / .po / .dsk / .nib / .woz images can be batch-converted easily with the HxC software to the HFE (v3) file format.
Tests status :
