Need clarification on Apple II Floppy cable pinout to Gotek

Post by Verault »

Hello. Due to floppy disks getting too pricey and unreliable and Apple II floppy drives getting more expensive every day I want to finally try out a Gotek with HXC firmware on an apple II computer.

I have already modded and reflashed the gotek and converted the .PO and .DSK disk images over to .HFE in the HXC software. Time to build the cable and test.

Using this page as a guide: https://hxc2001.com/docs/gotek-floppy-e ... apple.html
I am going to connect the Gotek to a Disk II internal card (IDC 20 connector).

So the data pins make sense.

"+5V (Int pin 11 / DB19 pin 6) <---------> Gotek +5V power input (Power pin 1)." This goes from pin 11 of Disk II card to the berg connector pin 1 of the gotek, so I got that.



Can someone please clarify this as I am looking at it and its not making sense to me:
"VSS/GND (Int pins 1,3,5,7 <---------> Gotek VSS power input (Power pins 2, 3) + Gotek floppy interfaces pins 33, 27, 23, 21."

Am I just tying all these together?

Once I have that ironed out I can quickly build up a cable.

Thank you!

So I finished building the cable. The gotek comes on but cannot see the usb stick. I tried the usb stick in my pc and its fried. I checked the power coming in to the gotek power input via the cable I made and its gets 12V instead of 5v.

What am I missing here? Can someone please help me out?

I have been a member to this board since 2018... But I havent posted much. Am I being moderated? Is noone seeing my posts?

Regardless I will keep posting my progress as someone in the future MAY see it.

I solved my issue.. I went over this thing 3 times and found some problems. (because I was tired and frustrated... two very good reasons to walk away from something and I didnt).

The 5v was supposed to come from Apple 20 pin header Pin1 to Gotek Pin 11 but I had it hooked up to pin 15 (12V)!!!

So I remedied that mess-up..... It was getting the right voltage but still wasnt reading my USB stick..

REMOVE THE JA JUMPER!!!

And its now working. I tell you we have made leaps and bounds in the past 5 years on disk imaging and emulation. A gotek, a kryoflux/Greaseweazle.. You can do just about anything now!

Strange thing though, the HXC website says you can use .PO disk images (but you need to convert them to .HFE format using the HXC software). It wont allow me to convert .PO files so Im not sure about that. .DSK files convert fine and thats what I have been using.

Edit:Someone suggested I try ciderpress to convert PO disk images to another format that can be changed to .HFE
Turns out the file format wasnt the issue. I guess the current firmware will only support 5.25" disk images although it doesn't clearly state that anywhere.

The HXC software is able to open any 5.25" PO disk images as well as NIB and DO disk images and convert them to HFE and the disk emulator can use them. It cant seem to do any 720/800KB disk images of any type and it doesnt seem to handle WOZ images either. Hopefully they can add that support down the road. I am happy with just 5.25" disk images for now, its a good start.

I wonder if the support can be added if folks have the smartport rom added via SoftSP card or proper floppy controller.
