This logic board idea keeps getting better. When I looked into dedicated controller boards, the ONLY Mac compatible controller board I could find was over $200 and would require a massive programming venture and learning curve, have very limited resources, and still have no easy means of interface. Browsing, I found a Quadra 605 on eBay for $1.00. It is starting to become obvious as to which device I will choose. :-) It would be especially great to be able plug a monitor *into* the rocket (internal video circuitry with external power source for monitor) and get data that way, and syncing it with an SE/30 or other compact on-site would be incredibly easy. I do have a few more questions: 1. What are the dimensions of a Q605 board? (I looked on the 'net and found pictures but could not find any physical measurements) 2. Is it reasonable to power a Q605 board from a battery, with maybe a hard disk for booting? How could I pull it off? 3. Is there any serial device that can do even simple "on/off" voltages to certain circuits, if I could find that then controlling valves would be very easy (solenoid switches to control liquid flow) -- and for data collection? Thanks a lot for all the help! Matt -- Compact Macs is sponsored by <http://lowendmac.com/> and...
