North Star Horizon

<[NS* terminal .vs. video board] < <Oh, agreed. The original Horizon configuration was to have a serial <terminal. I seem to recall a pair of 8251-based serial ports on the <motherboard, one of which was used for this. There was exactly that, two serial ports, a hearbeat interrupt and a parallel port. In the 78-81 time frame, most video cards were 64char and only some had decenders. Terminals onthe other hand were 80char, full upper/lowercase and generally required less software than a memory mapped display. <a serial port (and a standard MDA card), etc), I wondered if a Horizon co <be set up with an S100 video card as well. I guess it can. Most s100 crates could be...even a SOL could ahve more than one! <YEs, it does look to be a nice machine. One day, when I've got a few <minuts spare, I'll dig mine out again and look at it more seriously. After working with the Altairs noisy bus and toggling boot loaders it was a pleasure to see good signals and boot on reset. The IMSAI was a better machine than altair but when I moved up I really didn't want a front pannel and I needed more serial IO, the NS* box, CPU and the MDS I had in the altair solved most of my problems. CCS, compupro, altos, Vector and a few others had S100 boxen that were equal or better (compupro was really good!).
