Help with Memotech MTX disc format

Post by anvil1man » Tue May 17, 2011 7:58 pm

Hi, just got hold of the SD card version and am trying to figure out how to set it up to act like drive C (df1) so I can backup my MTX discs to SD card before they all stop working. Any help with the settings I need (am assuming it is in the raw option) would be appreciated. Jim

Hi, I have a working MTX with CP/M SDX floppy disc controller that boots from the 3.5" drive and reads a BBC cumana 5.25" as drive C type 3 DSDD drive. I am looking at copying these discs and putting them onto the SD card, or at the very least copying the contents of the discs and backing them up. Not really quite sure how to go about this with the hxc2001 as never done anything like it before.

Try to read some disk with the hxc floppy emulator tool :

Hi Jeff,

I had a play with it last night and think there (ie me) is a problem. I do not get the choice to select the drive (option ticked in settings) and it asks for a file and regardless what I select (I did put the config file on a clean sd card) it just says 'bad file' ?

How do you mean regarding reading the disk? Are you saying to get a PC running windows and then link up a 5.25" drive and try and read from the disk into the pc that way?

The user manual explains lot of thing:

Latest:

I have managed to get some images from MTX discs through my PC. With these it seems only the hfe ones will work on the adapter(am I correct?) and I am trying to get it to boot at the moment:

Select boot disc image
Drive light comes on 'RA' appears on the LCD
Computer says 'NO' ;-) Actually it just says 'please insert boot disc'

It therefore looks like it is trying to read the image. I am a little confused about setting up software though as looking at the HxcFloppyEmu software SDsettings there is little info to set apart from the drive interface type (MTX is shugart comp) where as on the load raw image there is all sorts of thing like track, sectors, skew etc.

Any pointers will be appreciated, the manual is ok but for someone with little experience like me a walk through from start to finish on the basics would be very helpful if one exists?

Attached is an image I have captured.

same thing, it is trying to access the disc but does not see the boot track by the looks of things.

When I took the image I simply selected 40 track, double step but did not make changes to the raw settings, should I have before trying to capture the image?

Attached is some pages from the FDX technical manual which may be of use.

forgot to add. Generally Memotech used three formats. Type 2 160k, Type 3 (most common) 320k and type 7 640k (both 5.25" & 3.5" drives used this format) the discs I am looking at for the moment are type 3.
