MMC2IEC
The MMC2IEC device
The MMC2IEC device simulates a 1541 drive and enables loading and saving programs to MMC or SD flash media with a C64. This project embodies a large code base including a FAT16/32 driver.

Nice joy, Lars!
The code is < 16K (without the UART debugging), so could it fit on an ATMega16? ('cause I already have a couple...)By gmoon on Feb 5th 2007
Sorry for the typo ...
Nice JOB, Lars!By LarsPontoppidan on Feb 5th 2007
Hi! And thanks
The atmega16 can't do it, you need at least 2 KB s-ram. Atmega16 has only 1 KB.By gmoon on Feb 5th 2007
Gotcha. Get some mega32s (or 64s) next order.
Thanks!By nojoopa on Feb 5th 2007
Wow!
I'd choose this over my 1541-III-DTV any day, mainly because PIC C development isn't really possible Linux (and I already have avr-gcc installed...) The directory support is nice for people with >512 .[dt]64 files (or >128MB SD/MMC cards).
Also... good job on your Wooden DTV :)By LarsPontoppidan on Feb 16th 2007
Also see the discussion about this project at Petscii forums.

Many thanks, Lars for making this.
And many thanks for making it work with a real Floppy now as well :)By 1570 on Oct 2nd 2007
Is the MMC2IEC board layout available (as .png)? It seems not to be included in the download.

I'm very impressed by how simple the PCB is. It's also given me ideas about building some manner of IO port expander with open and close statements to get and put data from the pins.

Nice project.
Could you please post the gerbers to the PCB layout or will you sell the blank pcbs ?By Rasputin on Mar 23rd 2008
Hello! Just a simple question: will it work the same with an ATmega32 @ 16Mhz?

Hi, This is a fantastic project!. I wish I had of found it before I ordered a Catweasel MK4 Plus @ AUD$180 :( Oh well. When the exchange rate improves I buy one of these also. And a Drive Parallel adapter as well.
I have a question though. Is there any chance of adding a daughter board for RR-Net (Ethernet) Ability?
Also could you in future designs expand the input voltage range to 5-14 VDC as most things here run 12VDC / (13.8).
Thank you so much for this wonderful open source project!. And such a sensible price also!. Many other options exist but they are many hundreds of dollars and un-affordable for most.
Best Regards,
Ken

Hi Again, NKC no longer has stock. :(
Such a nice project. As specially with the two din sockets fitted.
Will there be another batch?
Could also a new design come with header for RR-Net sub board maybe?
And wider Voltage range (0-14 VDC) ??
