On this day in 1977, the Apple ][ went on sale.
The base model had 4 kB of RAM, a 1 MHz 6502 processor, and could display 24 lines of 40 columns in 8-bit color. You could buy one for $1,298 ($5,029 today), or if you wanted to upgrade to 48 kB of RAM you would pay $2,638 ($10,222 today). It came with a cassette interface at first, then later with a 5¼-inch, 160 kB floppy disk drive.
I learned how to program in assembly language on one. Ah, memories.
