I am not a huge fan of the IBM PC. For one, it was a mediocre design. Most important, it caused a mass extinction in the small computer space so that, even today, the majority of desktop computers out there are distant descendants of the original 5150. They probably have a complete 5150 inside them, just for compatibility with ancient software.

My first experience with a computer as a child was putting a floppy disk labelled "King's Quest" into an IBM PC XT when my dad wasn't around. And now I'm on this forum.
I love the keyboard casually hanging off the desk like it’s not 20lbs!

Ah jeez, that makes me feel old. It’s particularly impactful as my dad worked in the computer industry at the time of the transition and the firm he worked for were a little late to the game. They limped on for years but ultimately failed.

I wonder what the average CS grad thinks of these days when they hear the company name "IBM".

Might be something like "IBM? What's that?"

It's been said that when Microsoft started to grow - say, in the mid-80s, Bill Gates' biggest fear was that it would turn into IBM.

Good news, it did not. It is worse.

Red Hat Enterprise Linux
That is the certificate I earned upon completing community college. Their Linux curriculum was originally designed around Debian, but when IBM acquired RHEL, redesigned to offer this foot-in-the-door.
IBM still seems to do alright in the legacy mainframe/mini market. It is quite strange how the AS/400 and zOS stuff all goes without notice of ordinary IT guys like me, as if it didn't exist, but still powers a lot of machine rooms that aren't AI data centers.

A lot of old mission-critical banking or commercial software systems have been running on those machines for decades. Before the AI age, it'd seem impossible to migrate those programs off. Now with the AI help, there might be a glimpse of hope.

System z machines come with special AI processor modules these days, so it's clear IBM wants a piece of that pie also.

I learned BASIC in 1981 on the TRS-80 Model I with 4k RAM (later upgraded to a massive 16k), and it wasn't long before someone showed me EDTASM [1], and I was hooked. My parents couldn't believe me when I asked them to buy "How to Program the Z80" by Rodnay Zaks [2]. They were shocked, it was the first time I asked them to buy a technical book. I was so excited I couldn't sleep for days. I was in High School, and I would carry the book around and read, use the lookup tables, and write Z80 assembly in my spiral-bound 8.5"x11" notebook.
One three-day weekend, I slept about 4 hours while I was disassembling the BASIC ROM to find nuggets I could call in my Z80 programs, and also to learn so much more about the video, the cassette interface, interrupts, etc. My notebook looked like something a madman had scribbled on the walls of an asylum to everyone around me, but to me it was perfectly organized, and I used it to reference things I would use later in my programs. I got to the point where I could read the hex dumps and "see" the op codes in my mind; people would look over my shoulder while I was debugging, and I'd be explaining what the code was doing, but I hadn't disassembled it yet. I didn't even realize I was doing that until one of my classmates pointed it out: "Hey, disassemble that. I'm not following you, how the heck do you see that?"
And all of this because my science teacher had that TRS-80 Model I sitting in the corner of his classroom gathering dust; nobody knew what it was, I didn't either, but I had to figure it out. I've always had this bug, I don't believe in magic, I want to know how everything works, it's been an insatiable thing all my life, that first machine set me on a course of learning for the rest of my life.
Thanks, Mr. Kruzan, you changed my life. I'll never forget you. Oh, and thanks to all the people who created the Z80, the TRS-80 Model I, and paved the path for me to learn computers and never stop learning.
We are truly building on the shoulders of giants; every generation, more giants. It's humbling to look back and think about it forty-five years later...
I learned BASIC in 1985 on an Apple II, and 6502 machine language in 1987, while in high school. I was able to publish a 6502 machine language program on a national computer magazine that year. Back then we printed the hex code of the program on paper, along with some explanation, then mailed it to the magazine. The magazine stuff manually typed in those hex code on the computer, and if they thought it worked well, they'd just publish hex code of the program and the explanation. Interested readers would then just typed the hex code into their computer to try it out.
The publication validated that programming was something I liked and was good at, which became the main factor I chose computer major in college.

For me it was the Commodore 64 from a few years later (1982, I think?) - that's what got me into computers. Back then, to me and my nerdy friends, the C64 felt sorta like a 'rebel computer'; we weren't doing Lotus 1-2-3 or anything practical at all. We were just tinkering, mostly war dialing and pirating games. The C64 was cheap enough that broke-ass kids like me could afford to do the same shit the Apple II and TRS-80s were doing.

Yeah. Thank you Mr. Pierson for lending me the TRS80 Basic manual, even though I wasn't enrolled in the class that used them...

It is one of those things, yes they are old but they also aren't that old considering the impact personal computers have had on everything.
