This advert is a sales-channel price list for later-model Commodore PET computers.

Prices ranged from £632.50 for the entry-level 16K 40-column 12" screen PET 4016 (about [[632|1981]] in [[now]] terms) to an eye-watering £4,020 for a 22MB Winchester disk.

That's around [[4020|1981]] in [[now]] money, or if the £181 cost per megabyte had stayed the same, a modern 2TB disk would cost about £380 million - even without allowing for inflation.
