I think there should be some kind of adjustment for the memory / disk space needed by operating systems at the time. A raw comparison is not very illuminating. DOS does not need and cannot use TB disks or gigabytes of memory, they are not meaningful. Modern systems need much more just to start.
To run MS-DOS 6.22 you need: RAM: 512 KB Hard disk space: 5 MB To run Windows 8.1 you need: RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit) Hard disk space: 16 GB (32-bit) or 20 GB (64-bit) Best regards, Kari Eveli LEXITEC Book Publishing (Finland) lexitec@xxxxxxxxxx *** Lexitec Online *** Lexitec in English: http://www.lexitec.fi/english.html Home page in Finnish: http://www.lexitec.fi/ 16.5.2014 16:59, Bill Troop wrote:
Since my first hard drive (for the NorthStar Horizon) in 1983, hard drive prices have dropped one-million-fold. That's not a guess, it's a calculation based on the $1,000 I paid then for 20 megabytes vs. the $100 you pay now for 2 TB.That's already a bargain compared to the reported $3500 Apple charged for a 5MB HD, or $700,000 per MB, in 1981. The hard drive was then already 25 years old, so you could get even more impressive factors by delving back to the first manufactured models and adjusting prices.
