Remembering Radio Shack's 1983 Training Film For the TRS-80 Model 100 (fastcompany.com) 72
Fast Company's technology editor Harry McCracken is also Slashdot reader #1,641,347. He contacted us Thursday with a story about Radio Shack's Model 100 -- and a rare training film from 36 years ago:
Radio Shack's Model 100 wasn't the first laptop -- but it was the first popular one, and an innovative machine on multiple fronts. It was also the last computer to ship with Microsoft software personally coded by Bill Gates.
I recently came across an internal training film intended to help Radio Shack staffers explain the Model 100's benefits to potential customers. I've shared it -- and some thoughts on the system's importance -- over at Fast Company.
The article calls it "an even more important computer than it generally gets credit for," noting portable computers at the time weighed a whopping 24 pounds -- and required a wall outlet to run. So a four-pound PC that ran off batteries and could fit in a briefcase "introduced people to mind-bending ideas such as using a PC on an airplane" -- even if it only had 8K of memory.

"8K of memory"
Holy crap. Even my Atari 800 had 48K.
Pretty amazing how far we've come.
I remember when the idea of owning an actual gigabyte of HD space was ludicrously silly, it was like saying that you owned your own Space Shuttle. It was so far fetched that we'd make jokes about it.

A computer wiz at work told me about using Debug to execute the HD controller firmware in ROM at address 8C something something. I discovered the interleave was 1:1 and the computer was taking like 4 or 5 revolutions of the disk to read a sector. Changed it to 2:1 and then it only took 2 revolutions to read a sector, greatly improving HD performance.
We've come a long way since then.

FOCAL. I remember bootstrapping it uo with octal codes on the keyswitches to get my FOCAL programming assignments done. There were also FORTRAN assignments for that class that we had to punch onto cards and bring to the batch terminal in the library building.

That overstates things a bit: a base pdp-8 could address 4k of 12 bits; it could eventually have another 8 of these ranges.
You needed a couple for the later "time sharing" that it would acquire.
It was targeted to be a device to support a single engineer; the multi-user was an odd thing to do with it when you got down to it (but it didn't take much more for an -11 with not much more spect to be multiuser)

You were lucky. My VIC20 had 5K of RAM, and just 3.5K available if you loaded the BASIC interpreter. The 16K expansion was $80. Today, $80 will easily buy you 16 GB of RAM [newegg.com]. That's a full 6 orders of magnitude of capacity per dollar, in just 25 years.
I also remember when I bought my first "big" hard disk, in 1994. It was 200 MB for just $400. I couldn't believe you could get a MB of storage for just $2... Now you can get 2 TB for $40 [newegg.com]. Five orders of magnitude swing in the price of storage.

8k standard, you can expand them up to 32k, and there are ROM cartridges available if you want more native programs than come on it from the factory.
Yes, I mean present tense, but these things were also available in the 80's.

Kyocera makes some very solid products that seem to last forever. The TRS-100 was typical. I've owned their printers, copiers, phones and many other devices that were only sold in Japan, and have never been disappointed.
They even introduced a dual screen phone back in 2011, called the Kyocera Echo. Way ahead of their time! I still have a very old Kyocera flip phone with the original battery. It just won't die, and I'm too cheap to give it up.

8K of memory is laughable today but that's about seven or eight double spaced typed pages of copy (oh stop laughing) which, again, back in the early 80's was incredible. For comparison, just about 10 years earlier the PDP-8/s computer we used in high school had 8K of memory and was the size of a small fridge so being able to carry around something like that in your briefcase was a revolution.

Battery life was much shorter using nicads, so I came with a couple of spare clips of four. Rather than 20 minutes warning when they ran low, you got 20 seconds.
