I've decided to made an Sd2Iec card for me and to my friends.What is that? Yap, it's an Sd card adapter for the commodore plus4 and C64 computers. Its act like a good old 1541 floppy drive, but you can use your fancy Sd card to store gazillions of floppy images. The hardware based on the
lordbubsy and
antabaka's sources. You can grab some more info:
http://sd2iec.de/ . Below you can see my first try to draw a pcb plan (with eagle) and on the left side of the picture the microcontrollers just received today.
There is a ready made version on
ebay.
In the next phase, i'll need to wait 3-4 weeks patiently to receive the other parts ordered from Hong Kong. (Crystal, cpu socket, sd card reader panel..)
