I spent some time tonight installing a couple JiffyDOS chips in my Commodore SX-64, and I took some pictures along the way. The installation is fairly simple, even though the SX-64 is pretty crowded. The performance improvement is impressive, and I love being able to just hit F1 to list a directory, instead of typing LOAD “$”,8 and then LIST :-)
