"How many on this board ever heard about "analog computers"? Actually, they are still around. I would assume they still have some applicability in process control and similar applications where there is value in eliminating the D/A conversion. Certainly, a different kind of animal from anything I've ever worked with (as a child, I built a rudimentary analog computer from an article in Popular Electronics, well before the first articles on building digital computers appeared there; but it was generally useless).

The +/-100v range op amps were built on tube technology. Back then one could even buy Heathkit style +/-10v rails versions of the same based on transistor technology! But of course the wider rail to rail made scaling much easier and improved precision. One of student friends had a full flight simulator thus simulated. I did a plastic batch reactor with forced water cooling as the temperatures tends to increase exponentially with the chemical reaction. Interesting stuff. Taro
