The Apple II (4KB of RAM) was introduced at $1298 in 1977, equivalent to around $2225 in 1984 dollars. But it didn't include a display (though you could just use a TV) or a floppy drive - the Disk II was introduced in 1978 for $495, about $790 in 1984 dollars. The Mac (128KB) was introduced in 1984 at $2495 - and it included a floppy drive, mouse, and integrated display.
