Gotek emulator for VME based OS-9 machine

Post by NenTech »

Hello,

I am working on a project for making machines more sustainable. I want to replace the floppydrive with an emulator. I bought a Gotek for testing. Maybe is a HxC better for future use (Since it is in industry)

I managed to format an empty drive with my OS9 PLC. I only get continuesly error 247 (SEEK ERROR - physical seek to non-existant sector.) when I want to make a backup of an existing floppy. Today I found a laptop with floppy drive. I was be able to dump the floppy to an image. The PLC can run correct from the emulated floppy. When I want to format the working floppy and back it up again via OS9 I get the seek error again.

When I compared both images with the Track Analyzer I can see what the error is. Does someone know which settings I have to adjust so I get the right layout of the images?

Hello,

Which Gotek (STM or Artery MCU ?) and firmware version are you using ?

For as far as I can see is it the Artery MCU. (Number on chip starts with AT)
Firmware version is currently the FlashFloppy 4.4a (Also tried 3.29)
I just got the firmware of HxC which I will try tomorrow. While backupping the disk the SEEK error's appear at random times.

Use the firmware HxCFEUSB_V4_2_1_1a present in the WIP_Firmware folder.

I finally managed it to upload the HxC firmware from the WIP folder.
Backing-up now works!

My next question:
With the FlashFloppy firmware I could see which track was used and wheter it was a read or write operation. (Tracknumber and last segment showed with upper dash writing, middle dash top head and lower dash bottom head)
Is this also possible in the HxC firmware? This makes it easier for me for checking the status of the process.
