As a great fan of 8 bit computers, when I see enthusiasm like this I get really excited! Back in my 8 bit days days I remember using Final Catridge extension for all my assembler needs. What would I give to have this baby - MMC Replay extension catridge which adds SD card reader and - ethernet controller to C64! Crazy! :)
Anyways, get your c64 from out of the closet, wipe dust and check out C64 Twitter client here.
