I had a new macro lens and I just started playing around with it. This is the CPU chipset plus memory controller from a Data General MV/7800 minicomputer (c. 1986)
So it had a āSystem Processing Unitā which consisted of 3 NMOS chips:
Microsequencer
CPU
FPU
Cycle time was 320 ns (I think thatās 3MHz)
I/O controller for Burst Multiplexor Channel (BMC) in CMOS ā that would be the one w/o the heatsink. This was basically the interface for disk.
I/O controller for data channel and programmed I/O (NMOS) This was the interface used by networking cards and the like.
Memory controller was an ECL chip from Moto.
The system had 2MB or 4MB options for on-board memory.
On the left a 7978 tape drive. The CPU box in the center looks like a HP3000 950. The 950 was HP's first commercial RISC minicomputer implemented in NMOS-III (?). The HP-UX version is the computer that saved HP and launched HP on the road to becoming the biggest computer company in the world. Also ran MPE-XL (later MPE-iX) for commercial customers.

Kitchen Computer, Neiman Marcus, 1969.
"The Kitchen Computer was featured in the 1969 Neiman Marcus catalog as a $10,600 tool for housewives to store and retrieve recipes. Unfortunately, the user interface was only binary lights and switches. There is no evidence that any Kitchen Computer was ever sold. Inside was a standard Honeywell 316 minicomputer, billed as the first 16-bit machine at that price from a major computer manufacturer."

Pretty much identical to the 21MX I used at Conoco
www.hpmuseum.net/exhibit.php?class=3&cat=33
(from earlier HP System)
My first real programming job was at Conoco from 1979-1981.
I was involved in the development of 8086 SBC based systems for offshore gas rigs in the Viking field.
The existing systems were based around HP computers, in particular:
- HP 3000 (mark I)
- HP 2100 and 21MX minicomputers
I did a lot of maintenance programming on these machines.
Fortran on the onshore based HP 3000 (which lived in our computer room at Theddlethorpe in Lincolnshire)
and assembler for the core stack based 2100s offshore.
I spent a lot of time with these machines.
I would fly offshore with paper tape versions of the software (and sometimes smaller paper tape patches).
The HP 1000s shown were the later version of the 21MX machines renamed but basically looked identical.
The core stack based 2100s were older and had illuminated push button front panels instead.
I entertained the offshore engineers by programming a āCylonā light sequence on the front panel in one version.
I also wrote a Fortran Lunar Lander game to keep the night shift operators entertained on the 3000 onshore.
Interesting aside - We had one of the few early Series 1 3000s in the UK.
The front panel switches (16 of them) were marked out in groups of 3 as we mainly used octal.
However the original panel was grouped from the most significant end so someone had tippexed in the correct grouping from the least significant end :-) .
Andika Triwidada is one of Indonesian's important figures in IT milestone. His early steps were surrounded by "dinosaurs", ranging from mainframes to minicomputers, various operating systems, made him a geek having a broad spectrum about IT, before jumping into full system administrator, infrastructures, then security experts.
It is very rare opportunity to meet him together with his family (especially his wife) in public IT gathering, so this was an exceptional moment when Andika's family went for Loedroek ITB gala-show last Sunday.
I requested a special shot, and asked a permission to publish as well. Unfortunately, I did not yet set my tripod up, the result is not so sharp.
This is one of my valuable collections, recording friends with his/her family.

I think this machine was used by Shell. The Line-printer looked similar to the one we had as well.
This minicomputer can be part your childās workstation to carry out his/her task of learning and tapping. In other words this leaptop looks like a laptop which is featured with tapping alphabets along with tracing the picture denoting that alphabet. For example, when a child is taps āLā, one will see a picture of lion simultaneously. Other than benefit of writing, a child can sing along 16 songs and melodies which are played from this leaptop and learn animal names too. Also a customized feature is in-built which can spell the name of child. Lastly, this compact & portable, kid-friendly and organically shaped replica of real laptop can result a perfect tool in a childās development and for learning stage. Secondly, the whole world is now into laptop and computers, to connect with each other for accomplishment of their goal, so why not the little one does the groundwork from now by working on his/her own laptop.

A teleprinter (teletypewriter, Teletype or TTY for TeleTYpe/TeleTYpewriter) is a now largely obsolete electromechanical typewriter that can be used to communicate typed messages from point to point and point to multipoint over a variety of communications channels that range from a simple electrical connection, such as a pair of wires, to the use of radio and microwave as the transmission medium. They could also serve as a command line user interface to early mainframes and minicomputers, sending typed data to the computer with or without printed output, and printing the response from the computer. Teleprinters are still widely used in the Aviation industry (AFTN and airline teletype system).

A Central Processing Unit (CPU), or sometimes just called processor, is a description of a class of logic machines that can execute computer programs. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage. However, the term itself and its initialism have been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.
Early CPUs were custom-designed as a part of a larger, usually one-of-a-kind, computer. However, this costly method of designing custom CPUs for a particular application has largely given way to the development of mass-produced processors that are suited for one or many purposes. This standardization trend generally began in the era of discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC). The IC has allowed increasingly complex CPUs to be designed and manufactured in very small spaces (on the order of millimeters). Both the miniaturization and standardization of CPUs have increased the presence of these digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in everything from automobiles to cell phones to children's toys.

William using a layout from the internet on his mobile to design his flashing lights display. He likes the Raspberry Pi Jam as there are so many more leads than he has at home so he can make more complicated things.
I have a long history with this one.

I worked for Conoco in the late seventies on process control software for offshore gas platforms in the North Sea. The systems in place when I started were HP minicomputers (3000, 2100 and 21MX) running FORTRAN for the onshore stuff and Assembler for offshore. We replaced the offshore systems with 8080 and 8086 based Intel SBCs running a mix of PL/M and Assembler code (we also did some stuff with UCSD Pascal - my first taste of p-code / bytecode).
As part of the job I got to go on a couple of training classes at Intel (if I remember correctly back when they were in Oxford before the move to Swindon) and to play Colossal Cave Adventure (ADVENT) on an Intel MDS (blue box) system running ISIS-II . I did manage to finish it later and even ended up getting calls from people asking for help as the tech support guy for our Intel distributor had pointed them to me.
Somewhere in my garage I have a stack of old printouts including the FORTRAN source and data files for this. I did my stint with FORTRAN many years ago and had almost as much fun working through this as playing the game itself.

Analog computer used gears, electrical parts to compute calculus needed to point guns to deliver shells on a moving target, including movement of the earth, against ships or aircraft. Was not replaced by digital minicomputers until 1970s.
Gyroscope enabled American ships to hit Japanese ships which could not hit weaving American ships, and had to travel in a straight line while firing, making them easy targets. Big factor in Battle off Samar when destroyers threw back attack by battleships and cruisers (but got sunk doing it)
