My first computer was an Apple IIe copy (Orange). I built the power supply myself and wirewrapped up my own floppy disk controller (didn't fancy using cassette tape). The I graduated to a Dick Smith Challenger, 80186 with 128k (later upgraded to 256k) and twin floppy drive. Next was a 286 12MHz with a meg of ram and 20M hard drive (later stacked to 40M), lashed out and got the EGA graphics as I figured I could keep the monitor the next time I upgraded
. Then a couple of Pentiums (can't remember details, but one had the "pentium bug") and currently have a 2.67GHz single core with 512M RAM.
Really looking to upgrade in the next year or so as it is really getting a bit old. If I run Stellarium and copy an image to the clipboard, I have to exit Stellarium so that I can paste the image from the clipboard into anything.
