I recently bought Ben Eater's 6502 kit. One of the things I've been meaning to do is figure out how to get it to talk to a serial port for terminal access. A while ago on YouTube, I watched a series where someone was restoring their IMSAI 8080 (the machine from WarGames) and learned it and the original Altair were a lot more capable than their front panels made them seem due to the S-100 expansion slots inside that sit on the bus. The first card the video showed was a terminal connection so he could send/receive commands using a VT-100 terminal (an emulator on a normal PC in this case). The cool thing I learned is that the way this worked is that the terminal board on the IMSAI would simply send the same screen info over and over again across the serial port, and it was up to the terminal to display this data on screen (making terminals like little dedicated computers themselves). I don't know how I thought this worked, but it was cool to see him debugging it. Seems a lot easier than trying to get a direct-connected display up and running and having to figure out all the signals and colors, etc. That said, I haven't actually done this yet, so the devil may be in the details. 1. https://eater.net https://eater.net 2. https://youtu.be/d_mWREmze5o https://youtu.be/d_mWREmze5o
