I threw away the 7400 series ICs in 2011 when we moved.

I never throw anything away, I still have a box of leaded resistors, capacitors and old 7400  series IC's from my college lab so why notkeep the old pants also. I don't think they will fit me anymore and I'm sure that if I tried to put them on my wife would send me to the Oregon State Hospital for a long long long vacation.

@mike_m

If you still have those bell bottoms, then you've got bigger problems than finding a pancake house.

Max, you did in fact post to T&M. I just found this post from another direction.

@Martin: As the test & measurement editor, I demand that Max cross post your next installment to the T&M Designline.

Eeek -- sorry -- I thought I had done so -- did you cross-post it already, or do you want me to do so?

@Mike: Since I'm just down the street from Beaverton I think I need to see if that pancake house is still there.

If it is, please send me a picture (max.maxfield@ubm.com) and I'll send it on to Sven

I'll try to keep the bell bottoms in the closet when I go to find this pancake house.

That's very kind of you -- thank you :-)

Sven,

There are many proprietary buses at that time. There are still some today but most test equipment uses GPIB, USB, or Ethernet with some also using RS-232/422/485 thought those are more for industrial use now. UAB has replaced RS-232 in many small pieces of test equipment.

Tektronix had built their own interface called the 1340 Data Coupler. The GPIB interface was developed by HP (called HP-IB) and I don't think Tektronix at that time would have used it.

Sven,

What was the interface from the PDP-11 to the instruments? If this was the mid-1970s or so, it night be one of the first National Instruments GPIB cards.
