“Assuming a non-Hollerith encoding with eight bits per column, and an MP3 file encoded at 128kbps CBR, there would be 36,864 cards in that deck, and the card reader would need a throughput of 205 cards per second. It might be wise to include an 8-column sequence number, however, so that a misordered deck can be repaired by a card sorter; with 72 data columns per card, the total is precisely 40,960 cards (40K cards), requiring a 228 card\/second throughput.” The 21 boxes of cards needed would by 5 feet 9 inches tall.<\/p><\/blockquote>\n

Punch cards<\/a> are before my time, so I can’t claim any direct experience with them. My earliest storage technology was cassettes on a ZX81<\/a>; now that was high-tech! \ud83d\ude09 I have to agree with his closing thought: “That such a huge leap in technology is well within living memory astonishes”…<\/p>\n
