We just have to keep in mind when we buy items to scrap that smaller means less weight as in small form computers as opposed to full size towers.
Another rule that is right more than wrong:
The newer it is the less it’s worth compared to its predecessor.
A ci7 from the nasa/usaf rickets will fetch a few hundred dollars in raw scrap: each. It’s a MCC the size of a piece of paper.
A via cha does nearly the same and is worth just a few cents as pinless.
My Atari example.
Let’s go extreme. A 10,000 dollar 1975 AV receiver with tuner with 6 input (RF, Paired copper) and 2 outputs—4 speaker terminals and RF— will fetch $50-$100 in raw scrap today.
A $50,000 receiver today will fetch about $25-$50 in raw scrap. Or less.
What was once etched gold and silver tracing and copper sheets gave way to gold wire gave way to todays <5nm processes of micro thread.
The cost of making has gone up. The materials value has gone down.
At Atari Woz was able to stuff half a meg into an 8” disk… but required 3 times the hardware to do so.
Bandshell put 500MB on an IBM hard disk platter… using a server sized writing cluster of mechanics!
Yesterday we had a full meg on a credit card called PCMCIA.
Today we have 500TB on a CD. Called Holographic 3D storage.
Two things are a constant in tech.
The same stuff does more
Less stuff does the same.
The reduction in materials to ability is measured in near infinite 0 ratios.
Meters became mili became micro became nano.
The Z8n, a variant of the 8080, is still used today. As a few dozen lines of code.
What took todays-value $100+ in materials now takes up a few microns of space.
