Viewtron and Videotex: Internet-like technology, circa 1983

Dave Farquhar Retro Computing March 3, 2012September 23, 2022

IT World profiled Viewtron, AT&T’s implementation of Videotex, as an interesting what-if. Think of it as 1983’s version of WebTV. What if it had caught on? Why didn’t it?

SCO v. IBM winds toward resolution

Dave Farquhar Linux, Retro Computing February 18, 2012October 30, 20181990s, AIX, AT&T, BSD, Digital Research, Gary Kildall, IBM, intel, SCO, unix, x86

Slashdot reported yesterday that SCO v. IBM is back on. Well, it is, sort of. The case never was fully resolved, due to SCO running out of money and filing for bankruptcy. Groklaw has the details.

If this sounds vaguely familiar, I’ll try to refresh your memory.

Happy 30th birthday, Commodore 64

Dave Farquhar Retro Computing January 6, 2012July 15, 20171980s, 1990s, apple, CES, commodore, commodore 64, Dave Haynie, emachine, IBM

The C-64 sort of turns 30 this week. It was introduced 30 years ago this week, though it wasn’t until August or so that you could actually buy one. It took that long for memory prices to come down to reach the target price, and if memory serves, the machine they displayed at CES in January wasn’t quite production-ready anyway.

I remember the machine well. It was my first computer. It seems like just yesterday the thing turned 25. And not all that long ago that I still used one on a regular basis.

Steve Jobs and the Commodore PET

There’s a nasty rumor floating around that in Walter Isaacson’s bestselling biography, Steve Jobs, Jobs alleges that Commodore copied the Apple II when making its first computer, 1977’s PET. Here’s the story of Steve Jobs and the Commodore PET.

The book doesn’t come right out and say it, but it insinuates it. I know how the PET came to be, and the PET would have happened whether the Apple II ever existed or not.

Confessions and rememberances of an Amigaholic

Dave Farquhar Retro Computing October 15, 2011October 4, 20181990s, amiga, bbs, commodore, Commodore Amiga, Dave Haynie, garage sale, garage sales, Toy Story, unix, Value Village, watson, watson road

My name is Dave. I am an Amigaholic.

I thought I was recovered. But I don’t think you ever recover. Not really.

You see, this week I was trolling Craigslist for garage sales. I look for trains, toys for my boys, and other things that strike my fancy. I spotted a sale that advertised an Amiga computer. I shouldn’t have put it on my list, but I did. I didn’t want to buy it, but I had to see it. I had to. Like I said, you don’t recover.

RIP, Dennis Ritchie

Dave Farquhar Retro Computing October 14, 2011October 13, 20111960s, DEC, intel, mac os x, motorola, os x, unix

Dennis Ritchie died this weekend, aged 70. You may not know who he is, but if you’re reading this, you’re using something he invented.

Dennis Ritchie was, among other things, co-creator of Unix and the C programming language. Even if you run Windows, Windows was heavily influenced by Unix, and a lot of programs you run were written, if not in C, in its successor, C++.

Was CP/M overrated?

Dave Farquhar Retro Computing September 27, 2011October 1, 20181980s, atari, atari st, Bill Gates, commodore, commodore 128, DEC, Gary Kildall, IBM, PIP, unix, vector, windows nt

Veteran tech journalist Dan Tynan recently published a list of 10 overrated technology products, and CP/M was on his list. But was CP/M overrated? I want to dig into that question a bit.

I think everyone knows the story of how IBM almost used CP/M as the operating system for its PC, but ended up using an upstart product from a small company named Microsoft instead. We’ll probably never know exactly what happened, seeing as the author of CP/M is dead and his business partner is no longer able to recollect those events from the 1980 timeframe, and IBM and Bill Gates have no reason to embarrass themselves by revisiting the story.

But CP/M was the first and most popular operating system for early 8-bit computers, so people who used it remember it fondly, and the way Microsoft steamrolled it made Gary Kildall and his operating system folk heroes to underdog lovers everywhere. Even people who never used it and weren’t even born when Kildall’s company ceased to exist have at least a vague idea of what it was.

Commodore 128, top-12 dud? By what measure?

PC Magazine presented a list of 12 computer duds, and while I agree with most of them, my old friend the Commodore 128 makes an appearance. Commodore released several duds over the years, but calling the 128 one of them doesn’t seem fair.

Happy birthday, IBM PC!

Dave Farquhar Hardware, Retro Computing August 12, 2011August 16, 20181980s, 1990s, amd, apple, apple ii, commodore, commodore 64, compaq, dell, Gary Kildall, hp, IBM, intel, lenovo, macintosh, Maxtor, pc magazine, Personal Computer, radio shack

The IBM PC 5150 turns 30 today.

IBM didn’t invent the personal computer, but if your computer has an Intel or AMD CPU in it, it’s the direct descendant of the beige box IBM unleashed on the world on August 12, 1981. Without a huge amount of effort, it’s even possible to run most of that old software on your shiny new PC. You probably wouldn’t want to, except out of curiosity, but you can do it.

I wasn’t one of the people who rushed out and got one. At the time, I was still watching Sesame Street and Mr. Rogers. I had my first experience with a computer–a Radio Shack TRS-80–in 1982, and the first computer my family bought was a Commodore 64 in 1984. Even in 1984, there were still plenty of people who questioned why anyone needed a computer in their home. My introduction to the IBM PC and PC-DOS didn’t happen until 1987.

Floppy disks for Commodore and other vintage computers

Dave Farquhar Retro Computing June 12, 2011September 9, 20181541, 1571, 1980s, apple, atari, commodore, IBM, vintage computer

It’s been many years since 5.25-inch floppy disks suitable for Commodore, Apple, Atari, and other vintage 8-bit computers (not to mention IBM PCs and PC/XTs) have been something you can buy at the store down the street. I found some 360K DS/DD disks on Amazon, but they aren’t available in huge quantities.
