SDrive-MAX by KBr#

English#

SDrive-MAX by KBr is an incredible smart device, which is highly recommended by AtariWiki. All data is stored on a mircoSD card (up to 32 GB and FAT32 format). The device offers the user 4 drives at one time and is connected to the Atari with a SIO cable. No further power supply is needed. Please ignore the power plug:

when dealing with the Atari over SIO and/or PC/Mac over USB. It can really damage the device! Please don't use USB and SIO at the same time! With version 0.5 SDrive-MAX can handle now ATX- and CAS-images! It can't be better! Now, Atari users on real hardware can deal with protected disk images. Of course, ATX support is currently limited and not all ATX files are supported. In 0.5, images with weak bits or timing based protection (e. g. skew alignment or duplicate sectors based on drive timing) will not work correctly. Version 0.6 will have support for weak bits but still won't support timing based protection. Maybe, timing-based problems can be solved in the future, but we have to see, due to the limited resources on the device. Thank you so much Farb from AtariAge for providing us with this information. Further, all stuff on just a single microSD card! That offers for the community to build a 'master microSD card image' for all. Just a host is still needed.

And last but not least: Thank you soooooo much Klaus! You really, really rock! Go ahead and a Tera-Thank-You in the name of the community! Incredible and outstanding work! We are as deep as the Mariana Trench in our debt! :-))))

Flashing for macOS#

> download the latest package
> download the latest firmware
> take apart 3 files: 'eeprom_writer.hex' , 'SDrive.hex' and 'sdrive.atr'
> connect Arduino via USB to your Mac
> open the Terminal app
> cd /dev
> ls -a
> search for 'tty.Serial...' or 'tty.SeriellerAnschluss' or 'tty.usbmodem14411' etc. ; (*) is defined as this string without ' ' and without any blank. Keep that string in mind, then type in: avrdude -carduino -pm328p -P /dev/(*) -U flash:w:<path to to this file>/eeprom_writer.hex
> for example: avrdude -carduino -pm328p -P /dev/tty.usbmodem14411 -U flash:w:/Users/AtariWiki/Desktop/eeprom_writer.hex
> then: avrdude -carduino -pm328p -P /dev/tty.usbmodem14411 -U flash:w:/Users/AtariWiki/Desktop/SDrive.hex
> flashing is now done
> disconnect everything, take a usb card reader and copy the file 'sdrive.atr' on the microSD card into the root directory
> reconnect everything
> congratulations to your new SDrive-Max software! :-)

Wenn man beim Einschalten des Ataris zusätzlich die Shift-Taste gedrückt hält, erscheint eine Zeile oben mit verschiedenen Option. Man muss aber weiterhin die Shift-Taste gedrückt halten und zusätzlich dann eine Auswahl treffen. Hat man verschiedene Dateien den jeweiligen Laufwerken zugeordnet und ist noch im Auswahlmenü, kann man mit Control und W die Laufwerkseinstellungen sichern. Beim nächsten Start werden diese dann automatisch zugeordnet. Somit eine sehr smarte Benutzerfunktion! :-) Danke Bernd, für diese wichtigen Infos.
