The other end of the wire is connected via one diode to the “free” pin of one button, respectively. On the pictures one can see the wire connected to pin 28. The diodes prevent that the buttons are short-cicuited and that signals on pin 28 coming from the bus can’t trigger an unwanted counting-up of the selected image. Using two schottky-diodes this “pulling to ground” is fed to pin 28 of the floppy-bus. That’s exactly what we need to simulate the media change. My solution relies on the fact that pressing the buttons pulls a dedicated line to GND (0V). Hence I present a “dead simple” solution for this that is easy to build and at least works like a charm for my Gotek floppy-emu: Putnik at this point for the analysis, further reading on this topic here.) A few older drives offered the option to get this demand by setting some jumper, but for modern drives or floppy-emus I’m quite sure there is no such option any more. So the disk change is not detected properly using the dedicated pin 2, but misusing the pin 28 (write protect) in that way, that this line is pulled to 0V (GND) for a short time when the user changes a disk. Unfortunately Atari saved a few pennies that days when designing the floppy-bus. The sorry subject detecting media(disk) change So selecting the desired disk via the two buttons and then using the program to write the ST-image on the disk. This, however, only worked running it on the Atari. (*) Using JayMSA I was able to write *.ST-Images on the virtual disks.

Since the disks are put sequentially as binary images on the key, it’s not possible to access any other than the first disk directly via the Windows Explorer without additional software.

In that case the program refuses to work saying it’s not a “FAT-12″ image file.

Trying to write disk-images with “strange” formats via the PC software.

If one tries more, one gets an “illegal sector” error.

Boot from the first disk (or the currently selected one if you do a warm boot).

Formatting HD-disks using the Atari, writing and reading, importing and exporting images.

Formatting DD-disks any arbitrary disk-format using the Atari, writing and reading, importing and exporting disk-images in any format(*).

Formatting virtual disks via software on the PC, writing and reading data, importing or exporting standard disk-images.

Maybe there’s also appropriate software for Mac OS or Linux, but I don’t know.

For comfortable disk management on the key one needs a PC running Windows.

Since the floppy-bus only runs with 500kb/s it doesn’t need to be fast.

One needs an USB-key with enough space.

The Atari (in contrast to a PC) expects the first drive to be ID0.

On the floppy-emu the jumpers “MO” and “S0″ need to be set (see picture).

Mixed operation with an additional, external drive may be possible, but hasn’t been tested so far.

So this means either the Ajax-FDC or a WD1772- 02– 02. That mean, it should run at 16MHz und should be able to stand this clockspeed permanently.

The floppy-controller already needs to be fitted for HD-operation.

The following criteria have to be met if one want’s to use the 1.44MB-model of the floppy-emu with an Atari:

Regarding this I found a PDF document on the CD of my version with the name “REPAIR SOLUTION – VB516.pdf”. If one has the old version, it is recommended to replace the resistors by 1 kOhm-resistors. If the value is 102 (= 1 kOhms), it’s already the updated version. One can distinguish the updated version by the values of “RN4″ to “RN6″ (red square in the picture). For the updated version certain chip-resistors have been reduced in their values, so that the detection runs reliable. “updated version” refers to a schematic error, that could have lead to the computer failing to detect that the drive is ready (please insert a disk…). On Amazon or ebay there are always a lot offers for about 20€ for the Gotek devices. Also, I feel the price of the HxC-emus a bit overdrawn. I decided for this paticular drive, because it (theoretically) can deal with 1000 disks and supports HD. This article should prove the opposite, since I successfully exchanged my internal HD-drive for the floppy-emu “SFR1M44-U100 updated version” from “Gotek”. One can find a lot of stuff and rumors about the “HxC floppy emulators” in relevant forums and also, that “cheap” alternatives won’t work with computers like Amiga or Atari.
