Re: Hitachi FDD-412A 8 inch floppy drive
This is the Pinout from the Hitachi Manual for the Drive.

Re: Hitachi FDD-412A 8 inch floppy drive
Dear Joe
Thank you so much for the pinout ... very useful!
If you are able to connect the FDD-412A drive to Standard 34 Pin IDC Connector I am very interested. Please let me know about your solution!
Until now I am not able to handle the data separator pins ...
Thx Martin

Re: Hitachi FDD-412A 8 inch floppy drive
For the 34 pin connector one needs to know if the FDD412A drive jumpered for RD or VFO?
Re: Hitachi FDD-412A 8 inch floppy drive
Unfortunately, I don't have any manuals for the FDD-412A drive or the controller, and I was not able to find anything on the Internet. So any more detailed description would be welcome!
Here is our current jumper assignment in the Okuma Campus 5000 systems: Thank you for your help!

Re: Hitachi FDD-412A 8 inch floppy drive
So my question is which set of jumpers are currently working in the Campus 5000?
The jumpers marked "original" or "maoles"???
And where did you get the other jumper settings?
I'm confused as you have a VFO drive, and are using RD jumper settings in one example and VFO jumper settings in the other.

Re: Hitachi FDD-412A 8 inch floppy drive
Sorry for the confusion!
The drives connected to the Campus 5000 are using the Master jumper settings! The Original jumper settings are not uesd in our system setup!

Re: Hitachi FDD-412A 8 inch floppy drive
My final goal is to emulate/replace the Hitachi FDD-412A 8" floppy drives with my HxC Floppy Emulators (either SD or Gotek)!
Re: Hitachi FDD-412A 8 inch floppy drive
Your "Master" configuration is VFO.
It will require a VFO board for the HxC to work with the controller.

Re: Hitachi FDD-412A 8 inch floppy drive
I still have some VFO boards here. These was made some years ago to connect the standard/classic SD HxC on some specific NEC PC98 computers needing the VFO signals. I think that they should work too here to replace this drive.
Another path is to use the Pauline dumper/floppy drive simulator : The floppy simulation is based on an FPGA and the VFO signals are generated by the drive simulator :

Re: Hitachi FDD-412A 8 inch floppy drive
Thank you joeyd! I will have a closer look on this as soon as possible ...
If you can share some more details about the Hitachi FDD-412A jumper settings (meanings of each jumper) this would be useful
Re: Hitachi FDD-412A 8 inch floppy drive
Thank you Jeff! I will take the VFO Boards in consideration ...Jeff wrote: ↑Sun Sep 27, 2020 4:00 pmI still have some VFO boards here.

I can provide the schematic if needed.

Only a few (4 or 5). Where are you based ?

hi, if you managed to get the emulator to work, i want to buy one of these, i have okuma lb12 lathe with osp, year 1987, used this 8 inch reader, wait for your reply thanks
