The forgotten computer that changed the world

Dave Farquhar Retro Computing , , , , , ,

A rather hastily written and sloppily edited piece showed up on Slashdot yesterday morning that caught my attention, because it was about the Amiga 2000. The Amiga 2000 is a dear machine to me; in 1991, our family upgraded to one from a Commodore 128. I still have both machines, and there isn’t much that I know today that I didn’t first experience on one of those two machines.

This is an Amiga 2000 that looks fairly pristine. Inside there was lots of room for hard drives, memory, CPU upgrades, and video devices.

Although I think the piece was little more than a used computer store’s effort to unload some hard-to-move inventory, I do agree with the premise. For a machine that had a tremendous impact on the world as we know it today, the A2000 is criminally unknown. Read more

The ultimate budget smartphone: The Moto E

Dave Farquhar Android , , , , , ,

I wanted to like the Moto E, for sentimental reasons. The Motorola who made this phone isn’t the same Motorola who made the MC68000 CPU in my Amiga, and it’s not the same Motorola that built the hulking briefcase-sized bag phone Dad toted around in the 1980s, but the logo is the same.

The stingy Scottish miser in me wanted to like the phone too, because it costs $129. A few short months ago, the only phones you could buy new for under $130 were cheaply made no-name phones like the Blu Advance with half a gig of RAM, a low-visibility screen, a low-end processor you didn’t want and an Android that was a few versions out of date, encased in lots of cheap plastic. Next to the Moto E, the Blu phones lose what little appeal they had.

The Warhol Amiga discovery in context

The Warhol Amiga discovery in context

A team of digital archaeologists recovered a series of images off floppy disks from Andy Warhol’s estate, including a number of experimental images created by Warhol himself. Judging from the comments in the various places that covered the discovery, the Internet is unimpressed.

Yes, these images appear to be the result of Warhol messing around. In many ways, they’re not all that different from what anyone might produce today messing around with a digital camera and a simple paint program with a fill pattern.

I’m not sure how many of the critics realize Warhol created this stuff in 1985 or perhaps even late 1984, using preproduction, prerelease hardware and software. All of it was likely buggy. And, as much as I like the Amiga, none of it was anywhere near today’s standards at that point. The stuff he had to work with was nowhere near 1989 standards–the Amiga in its early days was notoriously finicky.

Happy late 50th birthday, z/OS!

Dave Farquhar Hardware, Retro Computing , , , , ,

It was 50 years ago this month that IBM released the first modern mainframe, the System/360. The System/360 was notable for being the first series of systems built with interchangeable parts, rather than being custom-built. It’s also notable because its direct descendants are still in production: In the 1970s, it became the System/370, the System/390 in the 90s, and the z series today. The systems originally ranged from 1 MHz to 50 MHz in speed, and came with anywhere from 8 KB to 8 MB of RAM. To put that in perspective, the low-end model was comparable in power to an early Apple II desktop computer from 1977, and the high-end model was comparable in power to the 486 PCs we ran Windows 3.1 on in the 1993-94 timeframe. Or you could compare it to one of my souped-up Amigas, if you prefer (I do). But the same software that ran on the low-end model would run on the high-end model, and there’s a pretty good chance that software from the 1960s will run on a modern Z series mainframe today, with little to no modification.

Twenty years ago this architecture was supposed to be on its way out, but it never really went away. IBM keeps modernizing it, so I expect z/OS has a long life ahead of it. It’s entrenched, and when technology gets entrenched, there’s no getting rid of it.

There isn’t much new, young mainframe expertise in training these days, and it turns out there are certain jobs that mainframes do better than smaller PCs do. Most large companies have at least one mainframe, and it’s not going anywhere, but the people who can care for it and feed it are retiring fast. If you want some job security, you can do a lot worse than learning everything you can about IBM Z series mainframes in addition to the other things you know.

Training hackers in schools

Dave Farquhar security

I found this piece advocating teaching kids to be hackers. That’s hackers in a probing, discovering sense, rather than the trouble-causing, nefarious sense.

I found myself agreeing and disagreeing with this article at the same time. Not every hacker is a bad guy. And hacking is a mindset. But not everyone has the right mindset. Read more

The trade off of fidelity and convenience in marketing, and how it doomed my favorite company

Dave Farquhar Retro Computing , , , , , , , , , , , , , , , , , ,

I’m reading a book called Trade-Off, by former USA Today technology columnist Kevin Maney. It’s primarily a marketing book.

Maney argues that all products are a balance of fidelity and convenience, and highly favor one or the other. He additionally argues that failed products fail because they attempted to achieve both, or failed to focus on either one.

An example of a convenient product is an economy car. They’re inexpensive to buy and inexpensive to keep fueled up, but don’t have much glitz and you probably won’t fall in love with it. A high-end sports car or luxury car is a lot less practical, but you’re a lot more likely to fall in love with it, and gain prestige by driving around town in it. Read more

Getting past your own biases

Dave Farquhar Uncategorized , , , , , , , , , , ,

I read Andy Grove’s Only the Paranoid Survive last week. I always figured it was an autobiography or memoir, not a business book. But it’s a business book.  A very good one.

I avoided it because I didn’t like Andy Grove. I’ve never been a fan of Intel’s business practices during the 1990s and 2000s, including using payola to keep competitors’ chips out of large computer systems, but after reading this book, I’m more disappointed than anything. Whichever company had Andy Grove wins, period. No need to cheat. Read more

The Post-Dispatch may be giving the wrong idea about the dollar value of vintage computers

Disclaimer: I wrote this article back in 2014. I leave it here as a snapshot of the state of how things were in 2014. The situation at the time you are reading this is likely different.

Articles like Top 10 collectibles for value, from the Post-Dispatch this week, frequently make me nervous, mostly because of statements like this one:

[D]id you know that computer parts can bring home cash, too?

Statements like that tend to get people’s hopes up way too high. I find the timing interesting though, seeing as a TRS-80 Model 1 sold at a St. Louis estate sale this past weekend. The estate seller’s reaction? “Normally you can’t give that stuff away.”

Sculley on Jobs

John Sculley famously fired Steve Jobs in September 1985, a move that’s pretty universally panned today. Nearly 28 years later, Forbes asked Sculley about it.

Here’s the money quote:

“He was not a great executive back in those early days. The great Steve Jobs that we know today as maybe the world’s greatest CEO, certainly of our era, he learned a lot in those years in the wilderness.”

Something that shouldn’t be there

Dave Farquhar Retro Computing, Saving money, security, Toy trains , , , , , ,

I was standing in line to get a number for an estate sale this weekend–they’re what I do–and found myself standing a couple of people behind someone who talks too much.

I think some people talk because they want affirmation, and telling tales of what they’ve found is the way they get it. I’m very careful what I talk about, because I frequently see new people who look for exactly the same thing I look for, and if I just give away the knowledge I’ve spent years learning, it literally costs me money. But that’s not how a lot of people think, so if you keep your ears open, you can hear some good information.
