Arburg Multronica

Post by glenns »

Hello Guys,

I'm trying to get the HxC2001 floppy emulator (SD card version, from lotharek) to work on an Arburg Multronica controller.

the Multronica was made in 1996 and had a Mitsubishi MF355F-2252MJS(T) floppy drive. That was replaced a couple of years ago with a Teac FD-235HF-C929 and has the jumpers set for DS0.

Does anyone have any info on getting the HxC to work a Multronca?

Can you try to dump a Arburg disk with the HxC Floppy emulator software and send me the HFE file ?

Hi Jeff

Here is a floppy dump I have just done , I left the settings as standard so 80 tracks, double sided.

We currently use standard 3.5" floppies in the machine but we have to cover the high capacity hole or the machine will not work with the disk.

we also have to reformat the disks in the machine as it does no use a standard dos format. Hopefully you can work out what settings we need from the HFE file.

Hi,

For sure this disk doesn't use a standard format. A PC cannot read this kind of format.
We have the hardware to read & analyze this kind of format.

If you are ok, you can send me one or two disks at this address :

Where are you come from ?

I was hoping you were going to say that, I'm from england, I'll get a couple of disks sent over to you asap.

should I make sure they have data on them or just formatted in the machine?

Disks received !

This seems to be a custom FM format. I will generate for you some HFE file from these disks.

First try :

Tell me if you can read this image with the CNC.
(it's read only for the moment).

Nice work Jeff,


Copied the HFE file to the sd-card, connected up the HxC and it reads the programs perfectly.

Hi Jeff, any chance you can make us a writeable version of the hfe file?

Do you have abn oscilloscope ? What is the HxC / Multronica behavior when you try to write something ?

Hi Jeff, I didn't try to write before as you said it was a "read only" image so I've just given it a go but it just flashes a message saying read error (when trying writing)

I don't have an oscilloscope here but I can try to get hold of one.

Ok

First can you retry to read the files from this image ? :
http://hxc2001.com/download/floppy_driv ... onica2.zip

After this i need to know how the machine write to the disk.

From what i can see on the disk dump the machine write a full track at each write, but we need to confirm this point.
I need these oscilloscope capture to be done with the original floppy disk drive :

-Write gate signal and the index signal , synced on the index signal. (full view : 50ms/div and 2 close view : 5ms/div)
-Write gate signal and the index signal , synced on the Write gate signal. (5ms/div: falling edge and rising edge).
-Write gate signal and Write data signal, synced on the write gate. (20us/div: falling edge).
-Write gate signal and read data signal, synced on the write gate. (20us/div: falling edge).

Once i got all these elements, i will adapt the firmware to add the write support for this machine.
