[Coco] MC-10 Questions...

You know, as I was thinking about that digital dash again, it dawned on me that since it's feasible now except for the size of the CoCo board, would an MC-10 work??? I know basic is similar. But does it have two joystick ports, and do the ports work like the CoCo ports? Anyone see why an MC-10 wouldn't work? Basically I need two ports that need to be real time (within a second) for a tach and speedo. All these ports need to do is count a signal then mathematically convert to mph and display a number. My engine turns around 2400 rpm @ 75 mph, so that would be 2400 rpm in high gear. Hmmm... that's 40 revolutions per second (2400/60). The tachometer would read something similar, maybe twice that speed.  These calculations would have to be done simultaneously. The other gauges, fuel level, engine temp, oil pressure, and possibly volts (haven't figured out how to do that one yet, the other three are simple variable resistances that I know the ranges for) could be slower. The oil pressure will have a back-up warning light. The numbers displayed will have to be on a graphics screen to be big enough to easily see. I'd probably use a mechanical hour meter under the hood and forget mileage, unless I can find a stand alone odometer instead of an hour meter. 

Heck, I've forgot how I measured resistance now!! I remember using the joystick D/A inputs, but that's all. Got the idea from a game that used a series of push buttons for a Jeapordy style buttons connected to one port. I think each button had a different resistance and the CoCo could tell which button was pressed. Might have to have the gauges work in 5 or 10 unit increments, but would be close enough. 

Could the MC-10 do all this in close to real time??? Nothing has to be dead on, just close enough I don't run out of gas or get speeding tickets! Ultimately I'd intended to use a hot key to switch to graphic analog gauges for performance, and incorporate some trip computer functions (like at least avg. mpg and estimated distance on remaining fuel).  I doubt the MC-10 could do the analog gauges, I'd be happy with a big digit speed and smaller digit gauges placed around the central speed readout. That would have to be a graphics screen too. I have to re-learn BASIC anyway, might as well be MC-10. Any doubts that the MC-10 could accomplish all this?? There are several on e-bay now...

I seem to recall that I got individual gauges worked out on the CoCo, and a display, but never did get to the point of having everything work together in close to real time -- quit before then because I couldn't find a reasonably priced display and a tube type TV just wouldn't do in the car I had. An early 50s Nash would have worked, replace the round "unipod" gauge (looked like a big headlight bucket staring at you over the steering wheel) with a 5"-7" rectangular tube monitor. But that's not what I had or have!! A 5"-6" LCD screen is what I intend to use, can find them for under $200 with NTSC inputs.
