That was [CGA](https://en.wikipedia.org/wiki/Color\_Graphics\_Adapter). EGA was a serious improvement! ;)

I did that. I was working on a neural network simulator, actually [recreated here](https://www.codeproject.com/Articles/1035958/Neuro-Sim) 30 years later. The FPU dramatically improved performance, but it was still chunky.

You're right! EGA was the high res one that came later! Well ... 16 colours, up to 640x350! The first computer I bought for myself at home was EGA - the Amstrad 1640DD, with 640K RAM, twin 360KB floppies, Power supply built into the monitor ... and a MOUSE! I bought it a 32MB hard disk (a "hardcard" where the disk was mounted on the HDD controller card) which cost £400 and had a seek time of ~100ms! :omg:

This cartoon: UserFriendly[^] got me thinking: 36 years ago this month, the PC was released to the world for the first time. I was in the industry when it happened, and it didn't really make a splash immediately, but IBM made some huge mistakes back then: they made it extensible, expandable, and ludicrously expensive. Seriously: the basic usable machine (64K RAM, one off 160KB floppy, monochrome text-only monitor, and a keyboard) was priced at around US$3,000. A top of the range model with CGA monitor (16 colours text, 320x200 graphics in any four colours of your choice from the available 16, and a printer) was US$4,500. You could buy expansion cards to get more RAM - up to 640K! Two floppies! You could swap out the 4.77MHz processor for a slightly faster working (but same clock speed) V20 one, or buy a floating point processor and plug that in! So clones appeared. And boy, have they progressed! There are (from what I see on t'interwebs) well over 2 billion PC's in existence and working today. And every single one of them is thousands of times more powerful than the computers that got man to the moon and back in 1969. We - nearly all of us - owe our whole job to that tank of a PC (heavy? Nah - the keyboard alone weighed in at only 6lb) and I've been coding on or for the damn things for well over thirty years. Perhaps August 12th should be a worldwide public holiday?

We had one of those at the company I worked at -- I took it to a trade show and realized a few hours later I'd left it on top of the rows of public phone booths at the convention center. My boss was not happy. :(( Marc

Yes, I remember; I had the same model Amstrad running GEM! Who needs Windows, eh? Although my first home machine was a Commodore PET 40x25 screen. Later I bought the business version of the PET with 80x25 lines and a external twin floppy box (1.04mb each) that cost about 1,225 pounds!

Go ahead and take a look what a TRS-80 Model 3 or 4 would have cost. These were still typical workhorses at that time. Edit: Model 4 came later, that still leaves us with Model 3: 1980: July - Radio Shack introduces the TRS-80 Model III, priced from US$700 to US$2500.

I literally shouvelled shit ti help my school buy 2 model II's. Few months later was caned for playing on it when I was supposed to be in class (metalwork) - in font of the class. Ah memories, stuff that today's kids will never get the chance to experience. And I must admit: 1. caning (6 on the backside) really didn't hurt that much, 2. learning metal/woodwork back then means there's a lot of stuff I can do myself. 3. chainsaws are fun

GEM! Did you know it survived to this day? It enjoyed a long life on the Atari ST and the Atari OS was completely rewritten when Atari died. It has been enhanced since then and is still used on FPGA based computers or software emulators. That remiends me: I always wanted one of those FPGA boards.

Amazing how much the price dropped in the next couple of years...my parents bought us a TI/99-4a at the end of '83 (I think) for around $100. No monitor, just hook up the console to a TV! Also, no HDD or even a floppy...cassettes! I still have it in the box! :laugh:

I remember those days well. I was still in gradual school at the time. The original PC had a cassette tape or a floppy drive as options actually. You could also get your choice of CP/M or PC-DOS on it. Once 1-2-3 came out CP/M faded quickly. One amusing thing - the original v1.0 PC-DOS didn't even have directories. That wasn't until v2.0. :omg:

Dave KreskowiakI did not want to offend you. It's just that I met enough people who could recite all kinds of rules as if they were holy commandments, but had not the slightest clue why it's not always a good idea to use these things. I don't think that those people are dumb. They have been made that way by training them to obey rules without questions.

The prices dropped constantly as memory got cheaper and the competition got stiffer. The TRS-80 Model 3 was intended to be a professional machine with the best reasonable hardware options. Lots of memory, multiple disk drives, modems, large printers - all stuff that you did not find in a small home computer.

This [^] was my first laptop. Twin 720k floppies, 512k of memory, b&w cga screen. It would run for 5 hours on its battery which was handy because it would take 3 1/2 hours to compile and build a star-trek based computer game I was developing which left me an hour to actually do the coding and testing. I used to have a 4 1/2 hour train commute from Preston to London each week; down on Monday morning, back on Friday evening - spent the weekend with my wife. This worked perfectly for me for a couple of years.

Am I remembering wrong or did they have a full-sized expansion slot? I seem to remember trying to get one as our EPROM programmer at the time ran on a dedicated PC card and a big thick cable.
