Thanks Verity, that brings back memories!
I started my first programming job in 1988, coding image processing stuff on an 8 MHz 80286 with Matrox PIP1024 frame grabber. The latter had ONE WHOLE MB of video RAM so you could actually do something useful. I really needed some clever compression schemes to store images on the 20MB HDD. I still have some old Dr. Dobb's Journals from that time lying around, and even the last few issues of Micro Cornucopia to appear in print here in the Netherlands.
I still use some of the C code I wrote in those days. Stuff that ran quickly on a 286 runs like the clappers on modern kit, even without creating parallel versions of the code.
