Gender bender M-M, Terminator
Thinwire termination resistor 75ohm half watt.
Where's Aaahnold when you need him.
And an ooold style grounded socket.
4164-15 nine chips=64k RAM
Five sticks worth.
In 1984, each 64k was $100...
-15 was prob good for 4.77 MHz backplane
Need -12 (120ns) for 8 MHz backplane.
Anyone even remember this trivia? Or did most people just "leave it to the PC person"?
Meeeemories, like the shadow of my miiiind
And an old fashioned prybar that would have been used to extract a 386 chip...

TAKEN: V20 cpu
Drop in replacement for 8088.
First rolled out by NEC

Vrooom! The SPEED!
Overclock the bus to 7.14 MHz and it could almost keep up with 4.77 MHz with math coprocessor.
Modern microprocessor system design book
Dan mcglynn
The real telling thing about this book is the series of price tags, starting at $130, settling to $4 in due time.
AUI clip
Time was, used a clip to keep the AUI connector from slipping off. And a BNC connector for thinwire. Good old days indeed.
