Inside the TRS-80 Model 100 228
enalbro writes "What wouldn't you give for a laptop that starts instantly, weighs 3 pounds and gets 20 hours of battery life? That's the TRS-80 Model 100 in a nutshell. Granted, it displays only 8 lines of text and has just 28 kilobytes of memory, but it's a classic, the first truly popular portable in the U.S. At PC World we have a teardown that'll show you the guts of this featherweight champ." And, like many of the best things in life, it's powered by AA batteries (as is the Apple eMate).

These computers, as well as the TRS-80 CoCos and the Model I, III, and IV units... the units that saved programs to cassette, have greater wireless capabilities than our current hardware. All it takes is to plug in the input and output that are supposed to go to the cassette recorder, and patch it into a HAM radio. It's already being done. People are sending programs and information half-way around the world, without wires and without the assistance of satellites.

A few years later, I velcroed it to a pull-out rack shelf and hooked a null modem cable to it to monitor the console output of a SSL Screen Sound setup (proprietary pro-audio digital mixer/editor in the days before Pro-tools). It couldn't quite keep up with the 9600 baud stream if there was a lot of data streaming fast like during bootup. It did the trick, however, when you just needed to go in and check some of the statuses while the system was running. I think I mostly used it to go in and low-level format the hard drives on occasion.
It was useful for a while, and that must have been somewhere in the mid-90s that I used it.

What's interesting to me is the tension this sets up with operating systems like Vista which are moving in the opposite direction.
Just when the ultimate in MS bloatware comes out, suddenly a new (again) market appears for ultra-portable general-purpose PCs that can't run Vista.
So we have WinXP on the OLPC XO-1 and Asus EEE PC, etc., because Vista's too big and WinCE is too small. XP or linux+xfce are juuust right.
Personally I *want* my desktop to handle speech recognition and swooshy graphics if it has the beef. And I want my portable to have a huge battery life AND a general-purpose OS.
So I think this OS bloat bifurcation should continue.

External storage is an audio cassette. I think it uses the modem to generate the sounds for the cassette, but I could be wrong.
The OS does have a few bugs, where if a program does something bad (not using PEEK and POKE, but pure basic), or is too big to tokenize, it crashes and erases all memory. That makes writing big programs very exciting.

The Model 100 was a MAINSTAY of journalists at the time; since it ran for many hours on AA batteries which you could get anywhere, even in small towns in foreign countries, and it had a built-in modem and a very portable acoustic coupler that would work with any phone you could find.
