Yet another VT-100 emulator

Not the first time I've use dual-fonts. My Multi-channel datascope (MDLM) uses dual fonts so that it can display the data in a different character set than it's own displays. I use this for "partial hex" where all the non- printable characters are shown as HEX values, and "total hex" where ALL the data is shown in hex. Thanks. I just like to minimize the number of boxes that I need to have out in my workshop area. I've been using LAPTALK for years as my main "terminal", but with the recent acquisition of some VAXen, I decided it was time to make it as close to a VT-100 as possible. I agree - It's a good idea (thanks Mouse), the double VRAM use doesn't bother me (It's there, and not being used otherwise), but I don't really like the idea of rendering twice - especially if you want this to work on XT's and 286's (It would be slow enough rendering once!)... I haven't really done much with VGA at the hardware registers level, ut could ou use a different "color", and reprogram the controller to change he way that color appears on the fly? ... There are four attributes: Blink, old, underline and Reverse ... Underline and Reverse you can do in the rendering, so you would need to modify two colors to handle blinking (Blink alone, and Blink+Bold) - you would need to do this every 1/2 second or so. Not that I'm planning to do a graphical version just yet.
