Apple II-era machines. The monophonic synth reproduces eight drum sounds like bass, snare, rim shot, hand clap, tom, hat open, hat closed and "lazer," along with a sequencer that lets you plug in up to 16 drum patterns across 256 slots. Seems like just the thing for chiptune composers hankering for a way to make authentic eight-bit drum tracks using vintage Apple hardware. System requirements call for an Apple IIe, IIc, IIc+ or IIgs with 80-column capability and a 5.25-inch floppy drive -- you know, pretty modern stuff. A limited demo version is available, but if that doesn't satisfy, you can either buy it on a floppy for $14.95 or download a .dsk disk image for $9.95. Oh, and neither require a time-traveling DeLorean to go back to 1985.
