30 Years of the TRS-80 Model 100

An anonymous reader writes with this "interview with John R Hogerhuis, one of the key players in the still suprisingly active community for the TRS-80 Model 100 portable computer. As the Model 100 approaches its 30th birthday, John talks about what has kept the machine popular for so long, current software and hardware work that is keeping it relevant, and what modern developers could learn from spending some on a computer from 1983."

Apparently running the website, too

It must be running on one of those old beasties. :P

I've one of those on my desk at work.

Great curio. It runs forever on a set of AA batteries, and I've written a few BASIC programs to show it off. Once in a great while, I'll take notes on it, transferring back to PC via serial cable.

Love the keyboard, and the BASIC environment is the last OS type code that Bill Gates wrote.

Actually, ALL big-name home pc's are 30 years old.

[ihaveamo]

All the big-names are 30 years old just now.

This includes the TRS80 Color computer (The computer that got me into this crazy field in the first place... OS9 for ever!)
, Commodore VIC 20, 64, Apple II, ZX Spectrum, Amstrad They are all are / going to be in their 30's !!.

Who feels old now??

Sad state of modern technology ...

[Cassini2]

The Model 100 had a number of features that modern computers lack. If you need a simple computer to make notes, its battery life was in the 20 hours region. It was many many long years before the modern PC laptop was "portable" and had a battery life greater than 3 hours. (I'm thinking of some of the old transportables, which weighed 35 lbs and had no batteries.)

At long last, with the advent of the OLPC, the Eee PC, the smartphone, and a few of the smaller laptops, battery life has reached the 6 to 12 hours. However, for taking a piece of equipment to strange places with no power, being able to use AA batteries to power your computer is a really helpful feature.

Really wish the modern laptop could run from batteries longer. It's sad that a 30 year old PC is still competitive with regards to battery life.

It revolutionised journalism because it make it possible for articles to be written once and uploaded via a phone line. It must have put a lot of typists out of work.

What the Model 100 had going for it was that for the target market you could put in 4 new AA batteries at 8 in the morning, set the clock (if needed) and start working, and not need to be plugged in again until midnight. For writers, and people doing data gathering in the field, this really does mean that you can work all day. The keyboard pretty much feels comfortable, you don't have extra hardware to keep track of in the field, (where did I drop that wireless mouse again?) and so on.

No it doesn't have an HD or Wysiwyg display. It's not going to run 3d games very well. etc. You are not going to watch TV on it, or have it read that book aloud to you. It's not the latest and greatest hardware. On the other hand what it did, and for what it was capable of doing, there really was not a lot of competition. It's not the sexy gadget of the week for endgadget or techcrunch. That's OK.

I don't recall the specs of the model 100, but the model 200 had an Intel 80c85 processor, with 3 26k banks of memory available. Each bank was available to the user as 19k of usable memory. The 200 had a 40 column by 16 line lcd display that folded over the keyboard, and that device gave Tandy a patent on the clamshell design for laptop and pocket computers they earned royalties on for the next 17 years.

I'm not saying that it was the sexiest device. But you would be hard pressed to find a device in the digital technology sector that has put in as many hours of work in as many fields, as the TRS-80 Model 100 (and by extension 102 and 200) portable computer.

Emulator

Here's a link to the emulator: http://sourceforge.net/projects/virtualt/

Yep!

You can see many of his early ideas in how the thing operates.

Good times...

The Model 100 came out about the time I turned 18 and got an inheritance from my grand-father's estate. It was about five thousand bucks. Money was really tight and my new wife and I went round after round "discussing" whether it was more important that I get one of these devices or pay for something more "realistic" like things for the baby soon to arrive. I got one, but it wasn't pleasant. I still remember driving home from RS - had my wife drive so I could play with it - and being utterly enthralled with my new purchase.

Yes, the money probably could've been spent more prudently, but that computer helped launch my career in technology which has been, for the most part, very rewarding - my wife's not complaining about money, at least. After nearly 30 years, my wife doesn't argue so much about what I buy, my son has grown up and is doing just fine on his own, and my Model 100 is on the shelf right behind me. Still works, just like the day I got it.

Re:TRS-80, that brings back not-so-good memory

Hey what was wrong with the Trash 80? Not everybody had Apple money back then ya know. I had both the Trash and the VIC (Remember the Shatner commercial, complete with beam in?) and frankly they were great little machines for the time. Sure they weren't that powerful but then again a $10 cell phone is more powerful than the biggest computers were back then.

I think we would all do good to remember that the Trash, VIC, C64, BBC Micro and Sinclair changed a lot of folks lives and gave them a lifetime love of computing. Just think how different the world would be if those little guys never came out? if the only computers for sale in the 80s cost thousands of dollars? it would probably be a lot more empty place, with a lot less programs, tinkering, and DIYers out there.
