 |
|
These are mostly from boards I found last week.
First pic>>
I left the R80286-6 in it's original socket.
The Intel P5164-25 CMOS Static RAM's are the first I have seen. (I have 3 spares for sale/trade-if interested PM me.)
Second pic>>
The Intel NG82357 is an Integrated System Peripheral and the TMS320C25 is a DSP.
Third pic>>
The World's smallest chip collection--1inch x 1inch  (upper left)
The long "UMAX Scanner" chip is plastic and Gold (NEC D3777CY).
Below it are two image capture chips from an early Casio Digital camera.
The Signetics CN8008 was found hiding in a box of some other support chips.
I just noticed that it's an old CPU, maybe rare? |

Really?
It says 8008... 
Is there a Prom with same # as CPU? |

yup
It also has an HP house number on it '1818-0207'
a Intel 8008 would have a house number for HP like 1820-xxxx (and is in a different package)
