Hello,

 This is a tested and working project. (Tested on Commodore 64 and Commodore VIC-20)

This is an Easy DIY project, components are through hole, marked on the PCB, Easy to solder, Easy to make ;)

This is; SD2iEC (Commodore 64 disk drive emulator) powered from User Port (Micro-SD version).

This SD2iEC does not occupy the cassette port or expansion port of your Commodore-64 and allows you to use the Commodore 64 with datasette Cassette unit or Tape-64 and various cartridges like The Final Cartridge or Fast Load Cartridge or Action Replay Cartridge...

This SD2iEC PCB is also suitable for SMD ATMEGA644P and ATMEGA1284 in TQFP package, you can choose to use DIP or TQFP package. The DIP package is easier to program and solder, but the TQFP package AT644P or AT1284 is generally cheaper and easier to find than the DIP package models.

Original SD2iEC is designed by Lars Pontoppidan

With SD2iEC, from a regular Micro-SD Card; you can use D64, M2I, PRG, D71, D81 and P00 ... extensions, Commodore 64 floppy disk images and program files.

SD2iEC is easier to use and faster than most of its competitors. You can use SD Card as a huge capacity floppy or hard disk drive, you are not obligated to mount D64 disk images, you can load and save easily.

You can search and find a lot of information about "How to use SD2iEC" on the Internet.

This PCB is based on Ozay Turay's schematics.

 ** Before soldering SD Card Module you should place some isolation tape between PCB and SD card module.

** If you want to use SD2iEC unconnected to the C64 User Port then you need to provide DC +5V power to the (+ -) pins on the PCB. (DO NOT CONNECT EXTERNAL POWER SOURCE TO THIS PCB WHILE IT IS CONNECTED TO C64 USER PORT! )

In order to protect your electronical devices, always turn off your Commodore 64 before connecting or disconnecting any device.

While transfering data (reading or writing) from SD cards it should not be interrupted like power-off or Reset systems. Otherwise that may damage SD cards.

Gerber files can be changed at any time. Before paying for the PCBs, be sure to update your orders!

As you can see, I have uploaded many projects and still working on new projects. If you have any questions please search answers from the internet. Unless I explicitly stated, all my projects are tested under normal conditions and confirmed to work before being shared. I am sorry not having enough time to answer all the questions.

Use this PCB at your own risk !

Have fun

Thank you.
