If you really want to feel old try:
"I owned two eight inch floppy drives (180K bytes)."

O'well. I used to own a pdp-8 with two 4K core stacks and an audio caset
tape
recording the modem output for mass storage. Also the teletype model 33
(keyboard and hard copy output (printer)) for I/O. We won't even
mention the paper
tape reader and punch that was mounted to the side of the model 33.

Have fun.
