but in the time before digital gates and ยต-controllers, these were the only technology available. .... In the interests of accuracy I think the last sentence is not strictly correct. I remember using some of the very first 709 op amps in the early 70s and at that time the Fairchild 9000 series DTL chips were commonly available.
quoting Ian: "In the interests of accuracy I think the last sentence is not strictly correct" I moved to the US the first time in 69 or was it 70 and before that I did a design with 74 series TTL, so not even DTL was "modern" "in the early 70s". HOWEVER, at the same time, I also designed some analog using the 741 which postdates the 709. Erik |
