Turned out the output amplitudes from the 8970B were too high for the 1340A.

The Fairchild parts are optocouplers, and have their own self-contained LEDs.

The 16500B can use the HP mouse or the HP keyboard. The on screen keyboard does well. The touchscreen takes a bit of getting used to, but works well. No Fri, 20 Nov 2009 22:30:16 GMT J.

I built a box out of soldered-together pieces of double-sided PCB material.

Unless you know of someone who has a better price. If you do, I am sure we would all like to hear from you
