This is my first post on that forum I just discovered.
I bought recently a MMC2IEC from NKC . It works very well , but it use Lar's Firmware 0.8 .
I heard about a new Firmware (from unseen , i think) , that , if i understood well, allow to read use .D64 as it is a real floppy. Or at least, there is utilities that allow to copy the .D64 from the MMC2IEC to a real floppy on the 1541.
I have already found this firmware for NKC version on the net.
My questions are :
- Are .D64 becomes really readable? - How can we update the firmware? Do we need special hardware?
You need an AVR programmer to update the NKC via the 6 pin ISP connector on the board. Something like the AVRISP2 with AVR Studio is simple and easy to use . Personally I used the USBtinyISP programmer with AVRDUDE to update mine. You won't need to change any of the fuse settings unless you're adding a crystal to your board as well. (don't mess with any of the fuse settings at all!)
If you are into building projects (electronics), I built mine based from a parallel connector and Ponyprog's ISP programmer. I also used PonyProg as the software part of it as well. I also encountered a lot of learning about AVR fuses, etc... I must warn you that if you want to do a lot of AVR programming and experimenting, maybe you are better off in buying the finished ISP product in the long run (as most new PC's don't have parallel connectors anymore). Thought I throw my 2 cents......
