So we have been cleaning out the shed to prepare for a yard sale on Sep. 12, 2009. It has been an interesting journey since much of the stuff in the shed has not been seen by human eyes since the turn of the century. I even pulled from the very corner of the attic in the shed an old piece of training equipment that i used to learn electronics with at Snow College in 1975. It was a modular training system and quite the state of the art stuff in it's time but as I was graduating from electronics there were new things like transistors and Integrated Circuits (IC's) starting to appear in electronic equipment so the college was throwing out these systems to have room to bring in things they could use to teach the newer technologies to the students. So I decided to put these pictures on my blog just to give a little glimpse at what seems that not too distant past for me and yet is totally foreign to the youth in the age of PDA's, cell phones and ipods. They don't remember that a computer that could do less than their cell phone when it came to doing simple calculations in math were so big that they filled entire rooms of office buildings. I know because I toured one of them at the U of U when I was attending college.
These had different modules that you attached to the main frame and then plugged in various components to make the circut work.
There were resistors, capacitors, coils and other items that could be plugged into the back of each module to change the dynamics of the circut.
And on the front of each module you could plug in the vacuum tubes that performed various functions in the circut. Vacuum tubes, now there is something that nobody knows about anymore among the youth. (well maybe if they had a dad like me that just couldn't part with them quite yet and they had seen him remembering them as he cleaned out the old junk drawers.)
Oh well, I am personally glad we are past that age because they were a pain to work with and repair. Now we don't even consider it feasible to repair most electronic gear because it had been outdated before it is even broken in for good use and so we just throw it away into the growing heaps of electronic trash.Then once in a while an old piece like this even joins the heap.
