| February 18, 2006, 09:25:50 PM Megadrive128 LOL I think that's an ATmega128, AVR 8-bit microcontroller. I've started playing with AVRs, nice chips IMHO. |

Well, that means you are the copyright holder of that image and you may use it for whatever purpose you have in mind :-) You can always flip the hand horizontally and it will be a totally new image :-D |

| tnt23 Posts:195 | January 27, 2006, 04:40:43 AM No, it is not possible to populate MMC from the host. I am using standalone USB card reader for that purpose. Multiple drives can be implemented in future designs if there be any. Basically, only 2 drives will fit into 8M of DRAM the emulator has now. |
| adolescent Posts:3056 | January 27, 2006, 12:32:10 AM Great work! :-o Is it possible to load files from the host? (or, just from LCD/programmer control). Any plans to do one that can handle multiple drives? |

| tnt23 Posts:195 | January 26, 2006, 04:54:16 PM Thanks  This is my first factory made PCB.One IDC lead goes to programmer, another one is for LCD. |
| Matt_H Posts:6411 | January 26, 2006, 04:09:10 PM Looks good. :-) What do the two smaller IDC leads connect to? |

| CD32Freak Posts:645 | January 26, 2006, 10:14:01 AM Great stuff! Keep up the good work :-) It would be funny if you could modify the Kickstart ROM so it would show the hand with an SD/MMC card (like your avatar) instead of a diskette :-D |
