SO FUN FACTS about the TRS-80 Model 100:

It wasn't developed by Radio Shack/Tandy! it actually was a Japanese system, starting life as the Kyotronic 85. Tandy bought rights to the system, selling far more worldwide after the slow sales in Japan.

It was an 8-bit system, running an Oki 80C85 at ~2.5mhz, with 8-32 kilobytes of RAM. The 80C85 is an enhanced Intel 8080, making it roughly a Z80.

The firmware includes a version of Microsoft BASIC, as well as a small collection of built-in utilities: TELCOM (a terminal emulatolr), ADDRSS (an address organizer/phonebook), SCHEDL (a to-do list), TEXT (a simple text editor). You could save files to the internal RAM, and it used an amusingly limited filename system: 6 characters, plus a 2 character extension. So like DOS's 8.3 filename layout, but on a budget.

And Bill Gates being up there is not a coincidence! He reportedly had great fondness for the system, as it was one of the last projects where he provided a majority of the code. The TRS-80 Model 100 is Bill Gate's legacy as a programmer.

  TRS-80 Model 100 Portable Computer, 1983

[taperwolf]

I just realized I hadn't ever taken pictures of my oldest operational computer — from 1983, my NEC PC-8201A.

This hardware platform was designed and built by Kyocera, and variations were also sold as the Radio-Shack TRS-80 Model 100, the Olivetti M10, and the Kyocera Keytronic. It's based on the Intel 80C85, and came with 16k ram and 32k rom that includes the OS, BASIC interpreter, text editor, and terminal program. The screen displays either 40x8 characters or graphics with a 240x64 resolution.

When I got it, it had no power supply and a dead NiCad battery pack. I managed to find a brick-on-a-string power supply with the right voltage, and modded it to fit, and had a local battery shop rebuild the battery pack with fresh cells. I've been meaning to track down one of the battery packs for it that takes AA cells, but haven't ever gotten to it. Likewise, it's supposed to be pretty straightforward to connect to a more modern system via the serial port, or expand the RAM to 64k, but these are projects that I haven't gotten around to.

A look back at the sales training for Radio Shack's Model 100, a groundbreaking early laptop

When Radio Shack released the Model 100 in 1983, it was a breakthrough for portable computing: an AA-battery-powered laptop that you could fit in a briefcase, with a built-in modem and an instant-on Microsoft OS that contained the last production code Bill Gates ever wrote himself.

The Model 100 was so seminal that it had its own sales-training literature, including Selling the TRS-80 Model 100, an industrial training film designed to help Radio Shack clerks explain why a customer should shell out for the $800 system.

Celebration Clean Up Your Computer Month January 2021

Computers 13 we have all had to deal with them one way or another. From video games to social media, these technological creations also come with an important note. If we want to keep our computers running at optimum capacity, we have to keep them clean.

Both the components and the internal memory have to be cleaned regularly if we want our machines to operate properly. So, on that note, let us look into the ideals of Clean Up Your Computer Month!

History of Clean Up Your Computer Month

The first substantial computer was the giant ENIAC machine, created by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous calculators/computers. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes instead.

Storage in those vacuum tubes require the machinery to keep cool, taking up over 167 square meters (1800 square feet) of floor space. Nonetheless, it had punched-card input and output. It also arithmetically had 1 multiplier, 1 divider-square rooter, and 20 adders employing decimal 1Cring counters, 1D which served as adders and quick-access (0.0002 seconds) read-write register storage. ENIAC was productively used from 1946 to 1955. The 1960 19s saw large mainframe computers become more common in large industries, the US military, and space program. IBM became the unquestioned market leader in selling these large, expensive, error-prone, and very hard to use machines.

A veritable explosion of personal computers occurred in the early 1970s, starting with Steve Jobs and Steve Wozniak exhibiting the first Apple II at the first West Coast Computer Faire in San Francisco. The Apple II boasted built-in BASIC programming language, color graphics, and a 4,100 character memory for only $1,298. Programs and data could be stored on an everyday audio-cassette recorder. Before the end of the fair, Wozniak and Jobs had secured 300 orders for the Apple II and from there Apple took off.

Also introduced in 1977 was the TRS-80. This was a home computer manufactured by Tandy Radio Shack. In its second incarnation, the TRS-80 Model II, came complete with a 64,000 character memory and a disk drive to store programs and data on. At this time, only Apple and TRS had machines with disk drives. With the introduction of the disk drive, personal computer applications took off as a floppy disk was a most convenient publishing medium for distribution of software.

IBM, which up to this time had been producing mainframes and minicomputers for medium to large-sized businesses, decided that it had to get into the act and started working on the Acorn, which would later be called the IBM PC. The PC was the first computer designed for the home market which would feature modular design so that pieces could easily be added to the architecture.

Most of the components surprisingly came from outside of IBM, since building it with IBM parts would have cost too much for the home computer market. When it was introduced, the PC came with a 16,000 character memory, keyboard from an IBM electric typewriter, and a connection for tape cassette player for $1,265.

By 1984, Apple and IBM had come out with new models. Apple released the first generation Macintosh, which was the first computer to come with a graphical user interface(GUI) and a mouse. The GUI made the machine much more attractive to home computer users because it was easy to use.

Sales of the Macintosh soared like nothing ever seen before. IBM was hot on Apple 19s tail and released the 286-AT, which with applications like Lotus 1-2-3, a spreadsheet, and Microsoft Word, quickly became the favorite of business concerns.

That brings us up to about ten years ago. Now people have their own personal graphics workstations and powerful home computers. The average computer a person might have in their home is more powerful by several orders of magnitude than a machine like ENIAC. The computer revolution has been the fastest growing technology in man 19s history.

How to celebrate Clean Up Your Computer Month

To celebrate, all we have to do is turn off our computers and makes sure that the inside is clean and free from dust. Afterwards we need to reactivates our computers and clear up any space on the hard drives that we possibly can, and let 19s not forget to close up our computers after cleaning out the interior.

Evening all I'm reunited with my #Wifeidge after 4 long days 👍👌 it's that time again it's trivia time so D.Y.K What happened on 29th March?. . 1982 - Pixar’s Tin Toy Wins Academy Award, The first completely computer animated video wins an Academy Award for best animated short film. “Tin Toy” by Pixar (now a division of Disney) was an animated short film about a toy named Tinny – a one man band – who was being played by an infant named Billy. The short film lasted 5 minutes and cost $300,000 to make. The short film also won awards at the Seattle International Film Festival, World Animation Celebration, and National Film Registry. A sequel was in the works, but Tinny was not a popular toy for the kids. Therefore, the film was not made as Pixar concentrated on the movie “Toy Story”. . 1983 - TRS-80 Model 100 Introduced, Radio Shack introduces the TRS-80 Model 100, one of the first portable computers in a notebook-style form factor. The portability, simplicity, and built-in modem of the Model 100 made it very popular with journalists who could write stories in the field and transmit them back to their offices. Incidentally, in the early 90’s I acquired a Model 100 that had been used by a newspaper. I was able to use it to code simple programs, write papers, and use the modem to connect to bulletin board systems of the time. I recently found that I have 2 of these models among my tech junk – still in good working order! Good times, good times. . . . #TerrierByteIT #computerhistory #computer #technology #history #computerscience #tech #computerhistorymuseum #computers #retro #vintage #retrotech #trivia #oldtechnology #techhistory #technologyhistory #computinghistory #oldcomputer #oldschool #informationtechnology #thisdayinhistory #internethistory #retrocomputing #historyoftechnology #retrocomputer #oldtech #museum #vintagecomputer #computing

TRanSistors Part 2

This was one of the three mega exhibits for the 40th anniversary of the big three appliance computers launched in 1977.   Peter Cetinski, Kelly Leavitt, Dean Notarnicola (captain), his son Drew Notarnicola, & Jeffrey Jonas teamed up to display Tandy Radio Shack computers, primarily focusing on the TRS-80.

Seen here is the rarely talked about TRS-80 Model II, which was designed as more of a business machine than a personal machine.  This means that Tandy gave this machine a 4MHz Z-80A, 32K or 64K of RAM, the largest external storage mediums available, and a 12″ monitor -- nothing to sneeze at in 1979.

It included an internal 8″ floppy drive, but it was common to see it with a hulking bank of three external 8″ drives.  It isn’t common to see a model II running, but this is VCF East, and it’s no fun to display a broken computer.  I played Star Trek on it, however it was loaded from a modern CF card storage device instead of the original 8″ drives (which are apparently incredibly frustrating to fix).  I also played Worms, which was a pretty good snake game, even with the awkward controls. 

While they weren’t architecturally similar to the desktop Trash-80 machines, the TRS-80 Model 100, 102, 200, and even 600 series portable machines were a big hit.  A precursor to the modern laptop in terms of portability, these devices had full keyboards that would put many modern machines to shame.  The down side to this design was the limited character display, lacking a backlight or any serious graphics modes.  I still want one...

Stay tuned for the final installment of TRS-80′s tomorrow.
