|12:45 am - Upgrade time ...|
On Friday I gave my computer a little Christmas present, an upgrade from 1Gb to 2Gb. This was mainly driven by the way that Firefox seems to hover around 600-800Mb memory used (ok, I do have three windows open with about 120 tabs between them), which doesn't leave much for other apps. At the moment, "other apps" includes Gimp, which I'm using to scan medium format negatives (coming in at 7200x7200 and 150Mb each), which chews up memory quite greedily too. I suspect I've also got used to having 2Gb on my work laptop, on which I run zillions of apps quite happily.
Anyway, prompted by a recent post where someone listed the specs of the various laptops she's owned, here's a trip down memory lane and the specs of the various PCs I've had at home :
|Year||Model / type||CPU speed||RAM||Main storage||Graphics||Network/comms|
|1982-1985||System-80||2Mhz Z80||16Kb||Approx. 150k Cassette||128x48/B&W||None|
|1985-1991||Microbee||3.5Mhz Z80||64Kb||380k 3.5" floppy disk||512x342/B&W||1200/75 baud Modem|
|1991-1996||Generic PC||20Mhz 386SX||1Mb||80Mb hard drive||CGA, I think (640x200 / 16 colour ?)||2400 baud Modem (later 9600)|
|1997-2000||Generic PC||66Mhz Mhz Cyrix||256Mb||2.5Gb hard drive||1280x1024 / 24-bit colour||28800 modem (later 56k)|
|2000-2004||Generic PC||400 Mhz Pentium III||512Mb||20Gb hard drive (80Gb later)||1600x1200 / 24-bit colour||512/128kpbs ADSL|
|2002-2004||Generic PC||2000 Mhz Athlon||512Mb||80 Gb hard drive||1600x1200 / 24-bit colour||512/128kpbs ADSL|
|2004-present||Generic PC||2000 Mhz Athlon||2Gb||480Gb on three hard drives||1600x1200 / 24-bit colour||2 Mbps cable|
 Australian TRS-80 clone.
 Wasn't fully bitmapped, though, so couldn't use that resolution fully.

To summarise: Everything is from 1000-100000 times faster/larger/shinier now than when I started with computers. It might seem that display technology has stalled a bit in the last few years, but that's because I haven't listed 3D performance in the table - that's where all of the recent gains have been.
Current Mood: geeky
I bought a second hard 40Gb hard disk for my PC this week, more expensive because it's an external 2.5" drive ... and a couple of months back I bought an internal 320Gb drive for the PC.
For my first "real" home computer (an Atari ST Mega4) I bought a second hand 20Mb hard drive for £350 (which was a great deal in those days)
Price per megabyte, £17.50
40Gb external drive, £33, price per megabyte, £0.0008 (or a bit under 1/10th of a penny)
320Gb internal drive, £65, price per megabyte, £0.0002 (2/100ths of a penny)
40Gb drive, 21,212 times cheaper
320Gb drive, 86,154 times cheaper per megabyte (16,000 times the storage)
Scaling up that original 20Mb drive, 320Gb at that same price would be £5.6million pounds!
