The Schottky transistor allowed much faster gate operation. In this video the 74S04, a hex inverter package, is de-capped and the circuit is analyzed to understand why it runs so quickly.

Soon there was an explosion of companies offering a new class of personal (or micro) computers....
This example, the Quest Superelf, was a good example... it takes it's design cues from the mini-computers that preceded it. The 1st user interface is a console which allow code to be written in assembly and directly entered into the memory of the computer.

One of the more unusual item was an early attempt at an electronic key: a user would be issued a key which could then be typically used to allow access to equipment and to keep track of usage. Not very secure by today's standards.... but an interesting data point.

Optical mouse tear down here: youtu.be/sAklrT_HL0AHOW NOT TO BUILD A SEMICONDUCTOR LAPPING MACHINEelectronupdate2018-04-16 | One area of silicon reverse engineering which has interested me is the delayering of a chip to see each layer which allows superior visibility into the circuitry. I know of two ways: chemical etch and mechanical means.
In this video I try to make a mechanical grinder which can take micron levels of material away: a partial success. Parts are ground but I was not able to keep the silicon absolutely flat. More study of the commercial units is warranted!The 1st Programmable Logic Chip! Signetics 82S100electronupdate2018-04-08 | Back in 1975 the 1st commercially successful programmable logic part was released. A major step forward in allowing end customers to quickly develop products with higher density without needing to fabricate custom chips.
An important milestone in the development of electronics.
http://electronupdate.blogspot.comPDP 11/24 MYSTERY CHIP: MC8641electronupdate2018-04-02 | When looking at a old mini computer CPU card I kept running across a chip from Motorola marked MC8641.... no data sheets were readily available on the internet. I suspect this may have been a custom chip for DEC. In this video I tear down the chip to figure out what it is.
DEC was moving to too slow and the cost structure of this module would soon be very un- competitive: a look at the construction quickly shows why.
However! A good example of CPU card design of that era. This is DEC part number M7133 and it has a LSI CPU chip set known as the FONZ-11.DRAM DIMM TEARDOWNelectronupdate2018-03-01 | A look at the silicon and circuit board of a common DRAM DIMMSeattle Vintage Computer Festival Pacific NorthWestelectronupdate2018-02-15 | A quick video of some of the machines on display in this years festival.
