SD drive for atari 8bit 🙂  with few hardware changes:

 
  • no more SD CARD NOT DETECTED - avr and SD card talk to each other with no odd resistor dividers - just direct connection with SPI communication made the proper way
  • avr runs at 3v3
  • tiny AVR in qfn package, thus 14mhz at 3v3 possible and real
  • 402 smd elements used
  • level shifting between sio and avr REMOVED ! Atari reads 3v3 at sio port 
  • produced by smd.lotharek.pl  ;-)
 
 
 
Technical info: 
  • qfn main chip - 5x5mm
  • micro sd slot MOLEX
  • SMD 402 elements
  • transparent sio plug; SD CARD SLOT outside
  • PCB 1.6mm
  • Full ROHS

 

USAGE:  

  • 2 buttons: next drive, previous drive
  • 2 buttons pressed together - RESET of device; loader will load after atari reset
  • 6 leds: 2xRED ( sd act/error) , drive number:
    • D1: blue
