Quite a Memory
August 26, 2005
I just finished reading the excellent Dealers of Lightning : Xerox PARC and the Dawn of the Computer Age by Michael Hiltzik. It's a book that gives the inside scoop on the goings-on at the XEROX Palo Alto Research Center (PARC) in it's early days, the 1970's. One of the things one comes away with after reading this book is just how expensive memory was way back when. The price of memory had a shaping effect on most inventions that came out of the talented group at PARC.
This got me to thinking about the 32K memory expansion board I talked my parents into getting me for my TI-99/4A's Peripheral Expansion Box [more info at MainByte here]. I got it in 1983 and I recall it cost $299. For 32K. (Kilobytes, not megabytes.) My current main computer, a Power Mac dual G5 2.5GHz, has 2.5GB of RAM. That's 80,000 times more memory than the memory expansion board I had for my TI. That 2.5 GB cost me maybe $400. I did the math and discovered that if the G5's 2.5GB of RAM were purchased in 1983, the cost would have been $23,920,000.
Talk about tecehnology becoming more affordable....

I GBs worth of this kind of memory (not taking inflation into account--or facilities and air conditioning) would be around $208M! It's maybe 8"x8"x18" and weighs (I'm guessing) 30-40 pounds. Makes a cool paperweight! :-)

Think about it, that's 2048 characters/bytes! And let's not forget that it's Z80 CPU was running at like 0.2MHZ!
There was a bulky 16k RAM extension available, at a price higher than the computer itself! (Something like 150-200$).
My current Mac has like 20,000 times more RAM than this :)
I still have a couple of old computer magazines from the era, and these are really fun to read these days, if only for the prices :-)
Posted by: Marc at August 27, 2005 12:41 AMI'm only a young guy, but I've been building my computers for about 6 years now since I was 11. I allways decided upon what was worth upgrading and what was just enuconomical by thinking about where computer's would be in a few years. I remember four years ago, I calculated what 2 GB of good quality ram would cost, and it came arround to $2Gs. 500 GBs of HD space could cost over 1G, and and a multiple processor machine would mean a really expensive motherboard and 1G worth of CPUs. Now days you can get that ram fora few hundred, as well as the hard drive space, and as for multiple processors, you can get dual-core or hyper-threading at the average cost of a CPU
Posted by: Patrick Cieluck at August 27, 2005 2:08 AMIn 1972, my department at Stanford bought an HP 9830 desktop computer. It came with 2K of RAM. We decided to increase the RAM amount to 6K to allow us to run bigger programs. That extra 4K of RAM cost $4,000; i.e., $1/Byte. Therefore 1GB of RAM back then would have cost $1 Billion.

Live Publishing, the company behind magazines such as Retro Gamer and PC Utilities, is to cease operations by the end of the week, administrator BWC Business Solutions has confirmed to MCV.
The Macclesfield-based outfit recently pulled the plug on PC Extreme magazine, with production on all its titles now due to cease in the next few days.
“We have not yet been appointed as the administrators for Live Publishing but we will be by the end of the week,” BWC Business Solutions’ Mark Thomas told MCV. “The options open to us at the moment are either liquidation or administration. Either way, Live will stop trading by Friday.”
MCV understands that freelance staff have not been paid for a number of months, and the staff of Retro Gamer are said to have been made redundant on Monday.
The news comes after recent ABC figures revealed an overall decline in gaming and computer magazine readership.

Dang.
