I got it to work fine in one of my CNC machines, but the second one I tried was older, and would not work with it. It doesn't work with non-IBM drive systems though, like Shugart, which was very prevalent in a lot of non-PC devices. Compact Flash cards are a bit more expensive. The Datex unit I tried as well and it's pretty good at it's job.

It looks similar to the HxC unit I posted above. I tried the TOOGOO unit posted on Amazon. We junked it after two months of struggling when the one and only USB drive that worked with it (an old Kingston 2Gb they sold us with the unit) started to come apart from use. I never got it's serial-port mode to work reliably. It's extremely limited to what USB drives it works with and flaky at best. If it's using a proprietary system as the OP says it is, then it's OLD.

An "SD reader assigned to A" won't work because you can't connect it. Guys, this machine most likely pre-dates USB. This amazing little box has handled them all. Some of these systems and microcontrolers use non-standard, non IBM-AT floppy drive units as well. I've replaced floppy drives in CNC machines so old, they measure the maximum size of programs in "feet of paper tape". You can store several floppy image files on a single SDCard and use the buttons on the front panel of the unit to select and mount the one you want. You can open these special image files and drag-and-drop files into them as you would a ZIP archive. "Floppies" are created as files via a special program. It's designed to work with just about any system out there (NOT just standard PCs), and best of all, it's internal software is kept up-to-date by the enthusiasts making and using the units, thus, we haven't had an SD card it hasn't worked with. It's a floppy emulator created by legacy computer enthusiasts, for use in old IBMs, Atari's, Apple's, Commodore's etc. cards > 2Gb, or SDHC cards)Īfter about 3 or 4 of these units from various fly-by-night make-a-quick-buck electronic companies (most were mentioned above by other posters), I finally found this one: Most fail to work with MODERN SDCards (i.e. Decent hardware, but the software typically falls short.

First off, I've used several Floppy Emulators (floppy disk bus to some SD-Card / USB Drive interface).
