Use with LeCroy Oscilloscopes

Post by sreaves »

Hello,

Has anyone tried this emulator in a LeCroy LT (WaveRunner 1 or 2), LC or 93Xx series oscilloscope?

These scopes use Citizen WD1 or X1DE series floppy drives (I have also heard that the Sony MFC930's will work (the bezel is 1mm too high so it has to be trimmed) both use a 26 pin FFC interface so that would require an adapter to be made for the physical difference. The 93XX scope floppy disk controllers use a 26pin male (2X13, 0.1inch spacing) header.

These instruments format floppies and write files that are IBM PC compatible on 1.44MB 3.5 inch floppy disks.

I have attached a zip file that contains information on the floppy drive and the interface as well as a schematic of the floppy disk controller used in the instrument. Note that the drives are thin (11mm) tall drives that are used in laptops and the like. Standard floppy drives will not fit.

If the HxC SD version could be made to work there would be a lot of users that would be interested in them.

The attached zip has information that I have worked out thus far and the LeCroy Floppy Controller schematic as well as the floppy drive information.

Should works without problem (with the 26 to 34 pin adaptor of course ;) )

hi, I am interested in trying this product on my DDA-125. I saw the product page here
https://lotharek.pl/productdetail.php?id=94

is that what I need for my DDA-125? don't I need an adapter ribbon cable ? I read somewhere here that DDA-125 uses 26pin while this product uses 34.

any suggestions please

thanks

The ZIF SD HxC Floppy use an 26 pins ZIF connector, so this should be fine. You may need some additional pull up resistors (3 * 1Ko 0805).
