Never got to play with a TRS-80, but I did some interesting (but CPU-heavy and timing-sensitive) display tricks on the Apple IIe. Even without such tricks one could play with line offsets and produce more colors than the official 6 (in high res). Playing with video hardware is a lot of fun.

I'm guessing this has been posted in response to the recent article about the bsnes emulator. Interestingly enough, some bsnes forum-members have put some time and energy into exactly the sort of CRT-scanline emulation the article mentions at the end. For example, here's a GLSL shader that emulates CRT curvature, scanlines, and the Kell effect: https://gitorious.org/bsnes/bsnes/blobs/patches/snesshader/CRT.OpenGL.shader https://gitorious.org/bsnes/bsnes/blobs/patches/snesshader/C... ...and here's what it looks like applied to a screenshot of the Playstation game "Symphony of the Night": http://ind01.bilderkiste.org/2131284306277/SotN_crt.png http://ind01.bilderkiste.org/2131284306277/SotN_crt.png The original forum thread is here, but it's quite long and many different people post different implementations with different accuracy/speed trade-offs throughout its length: http://board.byuu.org/viewtopic.php?f=10&t=147 http://board.byuu.org/viewtopic.php?f=10&t=147

If you're in need of something archaic like the Z80, you need look no further than your trusty TI-83.
