For this week's MM theme, I again, thought of an old friend who's been with me for decades. We spent a lot of nights solving endless problems together and she always got me through each one of them. Things have changed a lot since but I decided to keep her all these years. I'm sure someone out there might still have a slide rule hiding somewhere.

 

GROUP: MACRO MONDAYS

THEME: NUMBERS AND LETTERS

SUBJECT: A LOYAL CALCULATOR

(less than 2" horizontally)

A vintage Texas Instruments TI-2550 calculator produced between 1974 and 1976 - one of the first hand-held calculators produced by TI. This one being a technological advancement of its predecessors by having memory and percentage functions. Originally sold for $99.95USD in 1974!

Yes, that is my TI-83+ on my desk. Be jealous.

 

A bowl full of integrated circuit chips and a DIP switch.

 

For the curious and/or pedantic, the chips are mostly 7400-series transistor-transisror-logic (TTL) circuits.

 

DIP stands for Dual Inline Package so technically everything here is in a DIP package but in common usage the groups of switches in this form factor are referred to as DIP-switches.

Well, i use this just about everyday as part of my job. HMM!

The calculator that got me through engineering school some 40 years ago. Just like back then, it gives the right answer most of the time.

The Texas Instruments TI 59 was a programmable calculator introduced in 1977. My father did an oilfield engineering degree with this one, i have the dock and printer s well, classic of early technology

This is a dramatized picture I took of my engineering Capstone team this year. They are working on a project involving optical spectrometry and miraculously we found a development board made by Texas Instruments which uses a DLP chip to perform spectroscopy. Even more miraculously, we got Texas Instruments to donate the board. So this picture is supposed to be them awestruck upon opening up the box containing the part for the first time. Notice they are all wearing matching purple team shirts. In that back are Wesley, Daniel, Zach and Cody. Up front are Kelly and Taylor.

How the old computer stuff is shaping up in the new place. It's still work in progress, but getting there I think.

 

I'd have some sort of competition to name everything you can see, but there's nothing that rare here and, anyway, a lot of stuff has the name of it on the front/top somewhere....hence I've tagged everything I can instead.

 

(that said, you don't see Atari 1200XLs, Philips N60s or Timex TS1500s in the UK that often)

Is this really familiar or is it just me? Found it for 20p in a charity shop and was sooooo excited! I don't actually think I had one but some friends of mine definitely did and I loved playing on it.

I think yes. Sorry I don't post. Unless you don't like my stuff, then you're welcome. ha.

Texas Instruments introduced the 900 series silicon transistors in 1954, the first silicon transistors in history. The upstart TI of Dallas managed to beat the established East Coast companies to the first silicon products. It was through the hire of important Bell Labs people in the development of silicon that enabled the feat. The higher temperature operation of silicon was preferable over the dominant germanium, so getting Si products into the market would give that company an edge.

 

TI started transistor development in Lemmon Avenue in Dallas and in 1958 moved to a 300 acre site at North Central Expressway. The Semiconductor building was the first building on the campus. The building is still there (although modified) and is now a Raytheon building following the acquisition of TI's defense business in 1997. I visited the facility during the 2000s and you could still see the roots of TI in the fabric of the building.

 

hfe=28, Vf=725mV, low gain but it was the first ....

Information from airhistory.net - thanks to Stephan Barth:

Texas Instruments operated a small fleet of Learjet 36s; their N1010A was just a year old when it visited Munich. The airframe is still on the FAA register in 2022 as N362PJ; however, last seen in 2016 at Hillsboro OR, it seems to have been withdrawn from active flying.

I am surprised that I used exclamation points for vertical bars. Maybe I didn't know how to type a vertical bar yet—the TI-99/4A had a weird keyboard.

Inside Burr-Brown / Texas Instruments isolated DC/DC converters before being embedded in semiconductor plastic packages.

Clive Sinclair formed Sinclair Radionics in 1961, having a good understanding of electronics and transistor manufacturing. Always the entrepreneur he bought a quantity of transistor test failures from Semiconductors Limited (Semics) of Swindon. As seems to be the norm in British semiconductor history, it was convoluted. Semics was actually Plessey who had licensed Micro Alloy Diffused Transistor technology from Philco in the US. Sinclair used the transistors in a very small pre-amplifier and sold both the amplifier and retested/re-badged transistors separately.

He must have done this again as ST140 and ST141 transistors were on the market, albeit probably in relatively small quantities again.

Above is an ST140 Sinclair transistor. There is also an original Philco MADT transistor. In the middle is a UK manufactured Texas Instruments transistor.

Texas Instruments opened a semiconductor plant in Bedford, UK to manufacture transistors, before moving onto standard logic during the 1960s. It eventually closed in 1994. Sinclair became a large customer for TI in the UK through its various Hi-Fi, micro TV and other products including for the supply of custom ICs. Unfortunately the supply of custom TI ICs was problematic and Sinclair went back to standard logic for the ZX80 home computer and Ferranti Uncommited Logic Arrays for the ZX81 and ZX Spectrum.

 

The ST140 is an npn, hfe49, vf=715mV, so silicon.

Thanks to Martijn Boer for providing the board with this chip on it.

 

This chip was really hard to identify, and I had to dig up some Nokia 5110 service manuals and technical documents to even identify it and get a rough idea of what it does. Upon searching the writing on the chip package, I found nothing relevant, so I went ahead and cracked it open in hopes that an on-die marking could help me out. At the center of the chip there is some inscriptions which gave me some clues. First off, the TWL91310 or MSW/ABB strings did not bring up anything. The COBBAGJ string is what led me to discover the Nokia 5110 service manuals which told me what this chip is. Also on the bottom left there is the Texas Instruments logo and a timestamp for 1999. This leads me to believe it was probably a custom design requested by Nokia since you can usually find Texas instruments datasheets quite easily.

 

Here's a section from the technical documentation explaining what this chip does:

 

"The COBBA–GJ provides an interface between the baseband and the RF–circuitry. COBBA–GJ performs analogue to digital conversion of the receive signal. For transmit path COBBA_GJ performs digital to analogue conversion of the transmit amplifier power control ramp and the in–phase and quadrature signals. A slow speed digital to analogue converter will provide automatic frequency control (AFC). The COBBA asic is at any time connected to MAD asic with two interfaces, one for transferring tx and rx data between MAD and COBBA and one for transferring codec rx/tx samples."

 

(MAD is the main processor of the phone, largest chip on the board)

 

So it appears to be responsible for some cellular signal processing. In other places in the technical documentation it also talks about how this chip handles some audio processing and codecs as well.

Back in my hands again. This system has spent the last 20 years at my dad's house. I shipped it his way when I started using IBMs at work in college. He wanted to get more familiar with computers.
