West Lothian was the centre of much ‘high tech’ industry. By 1980, there were 30 electronics companies in Livingston New Town. This led to the town being known as the capital of Scotland's Silicon Glen and, in turn, attracted a number of Japanese companies to set up operations in Livingston.
This microprocessor (American) was used for managing liquid crystal display (LCD) at Millard Associates.

Early view of the board--just about what I could get done between 415 and 745 a.m. on a Sunday morning. Kids are up, and now Dad's on duty!
This image is taken with an 18-55mm VR lens dismounted and handheld in reverse.
This lens is currently not mounted.
This has potential, I think I will buy some reversing rings to play around with.
The microprocessor. They were mostly made by Rockwell. This was an 8-bit 2MHz device. Remember this was 1981 onwards :-)
The Samsung NP305 laptop had a very poorly designed DC power input jack - just look at all the replacement parts for sale on eBay! After one repair under warranty where they replace the entire motherboard (part #BA92-09477A, costs AU$150 new), the unit owned by my sister failed for a second time, so I came to the rescue and repaired it myself with a AU$2 replacement part.
Están en el interior de mucho de lo que nos rodea.Todas nuestras infraestructuras están controladas por aparatos que los contienen...y muy pocos de nosotros los comprenden.Nos son tan extraños como aquellos que los producen.
Extranjeros, nuestra economía depende de ellos igual que nuestro bienestar se asienta en el expolio de las regiones que contienen los minerales con los que los fabricamos...depende de ellos igual que dependemos de la explotación de poblaciones en lugares lejanos...
three sets of patches. 2 resistor networks needed their values halved so I paralleled an identical (47 ohms) one across the existing one. that's one patch.
another patch is to have pullups for the TI branded port expander chips. that's the 2nd set of yellow r-networks (the ones to the far left in the photo).
the 3rd patch is where I had to use a too-small r-network on top (not seen, would be far right set of SIP pins) but I didn't bend the leads over to get the 'power dc' led wires. some small solder bridges across adjacent pins fixed that one.
the board is now ready for operation in the real word (lol).
The Raspberry Pi is a low- cost, credit-card sized minicomputer. It is a powerful device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a regular desktop computer to do, such as searching the internet and watching high-definition video or making spreadsheets, word-processing, and playing games.

One of the three video controllers on the board. Seems to be a National Semiconductor 525T Video Controller?
This is what my fancy new macro lens was actually bought for.
This is a 4x4mm ASIC chip (application specific integrated circuit) which drives our sensors.
