I bought the TRS-80 as soon as you could buy one - I bought the 16k RAM module right away. I tried basic and wanted to move a pixel across the screen. It was painfully slow. I read about Z80 machine language - I went out and bought the compiler. I wrote essentially the same code but it didn't seem to work. The pixel was on the left - and then immediately on the right. I didn't realize initially that the code executed so fast you it wouldn't light the phosphor on the screen. I spent HOURS AND HOURS on it - in fact the box it came in was my "desk" for a long time. Fond memories. I am now 66 years old - have had a long career in software development - including being in leadership for over 20 years - I am now back to writing code and I love it. I work mostly in JavaScript (React and ReactNative) and PHP. What a long strange trip it's been :).

The very first computer I ever owned. The model 3 was my second computer, and the Tandy 1000 was my third. The 1000 was also the first computer we added a “ Hard Drive” to. I can remember well as a child waiting for games to load from the tape drive while sitting at the dining room table we only used for my dad and I hobbies!

For those of us who worked at Radio Shack at the time, it was Lew Kornfeld that ran the business "hands on" at that time. Charles Tandy had final approval of these things, (including Tandy Leather and Color Tile stores) and died a year after the TRS-80 was introduced in 1977. It had no model designation at the time, just a typical 26 series part number. The initial production run was small enough that they could be used in stores for administrative tasks if they didn't sell. LOL.

Fun Fact: AI chatbots are basically just Eliza with the ability to learn new responses. Yes, they're very much more complicated than Eliza, but all of the complexity is in the ability to learn new responses. The responses are still pretty much "canned" only we don't notice that since the machine is continually updating its responses using input from other people and other text resources.

The good 'ol TRS-80 model I -- the first microcomputer that I'd used (back in high school). The school got the TRS-80s back in 1979/1980 school year -- mainly as they were the best deal at the time (Radio Shack was offering a better deal to schools at the time, and Apple had yet to start giving "killer" deals to schools). I did eventually acquire a Model I when helping one of the professors I knew at university clean out his garage. As he was planning to scrap it, I offered to "adopt" it. It was in working order at that time too. Since it's been some time since it was put into storage, I'll need to give it a thorough cleaning and checkup for any parts that could have failed before I try turning it on again. Since the unit that I've is an early example with Level I BASIC ROM, I'll probably should locate a copy of the keyboard debounce patch.

Wonderful to see. It appears to be the exact model I had (Level II 16K). At 6:02 there's mention of the logo on the keyboard at the right. Mine actually had a numeric keypad in place of that which came in handy. At 5:10 presenter makes mention of a 'bounce effect' when pressing keys. What a pain that was. It was so bad that I developed a type of slap/tap techinique when pressing keys to minimize the repeated keystrokes. Eventually I was able to buy a cassette tape which contained a program you would load that would remove that effect as mentioned. What a relief! At 11:15 was an oh! moment I completely forgot about. There were 2 modes. The standard and then another mode where everything was larger on screen. There were a couple of ways one could place graphics on screen through its basic language. The standard was to simply plot a pixel at a location. Another interesting thing they did was make a kind of character code set. I recall it as a 2x3 pixel grid (64 possible combinations/codes). This would allow you to place 6 pixels on screen at once which was a great performance alternative, otherwise one would have to resort to using Z80 machine lanugage for speed. One interesting thing as I understand it was that the operating system was actually made my Microsoft. 16K of memory was pretty good at the time. Me and a friend took turns typing for 7 hours entering a game (Sea Battle) from a book which entirely filled the 16K. The cassette tape for program storage was a good memory. When I wasn't loading a program I would use it to play one of many music cassettes I had. The following PC's I had such as Commodore Vic 20 and TI99 4A, I would use my dads big reel to reel tape which even had a fast mode for greater reliability which did the trick. This unit would get very warm even after an hour of use. If you flipped it over it had some ventilation, and you could see through that a very large cylindrical blue tube. The unit cost at the time (early 1980) with numeric keypad etc, was $1200. When you think about it, buying a decent PC now a days is about the same price after 44 years. And while we're at it, a decent sandwich then would cost $3 to get me through my computing day. I still pay $3 for a sandwich at a sub shop I've gone to now for 40 years. You know, this world of PC computing may just be inflation proof! :)

The real problem with the series of TRS-80 computers is that when they made the first they thought that is was finished. When the Model 2 came on the market, it was not compatible, and the Model 3 was again not compatible with Model 2. If Tandy would have made a second computer that was an expansion to the first model than there would have been something like an evolution and than improvement would be a stimulance to expand or buy the bigger model. What they did was produce new models that were in competition with earlier models, that was counter productive. Eventually they did not survive.

The TRS-80 Model 1, with a panasonic cassette player, was the first machine I got to program on. I had to wait for my mother after school 3 nights a week, and was too young to be home alone. (about 8), So I went to the Learning Resources Center at the community college where she was taking classes (the campus and my Elementary school were adjacent.) The LRC staff decided I should get something to do besides read or watch 8mm science films... so they handed me the "Programming your TRS-80 Model 1" book (suitably taking custody of my school ID for the duration) and showed me the 3 minute overview... I worked through it, but didn't grasp enough to do anything interesting other than cheat on my math homework... But once I showed I could use the TRS-80, they let me do some edutainment stuff; they also let me use the Apple II+, at least if no college students needed them. I wasn't the only kid from my school doing so - R. V. also had to meet her mom after school a few days a week. First computer I ever used was an Apple II. Not a plus, the original Apple 2. I was 6. It was in the school library.

I remember using a TRS-80 with Level 1 BASIC. I've read that this was a "stopgap" release until Tandy could get a license to incorporate Microsoft BASIC into their computer. I remember two of Level 1 BASIC's quirks in particular: Firstly, you could type a calculation into an input prompt which required a numeric input, and the computer would calculate the result and then pass the result to the variable. You could even use variables as part of your input, so if you knew what variable held the answer to a question, you could type the variable name in order to get the correct answer without knowing it. Of course if you knew how the computer calculated the correct answer to something, you could just type in the formula to again enter the answer without knowing it. Secondly, the keyboard was active all of the time, even while programs were running. This was used in one particular game which used the text-only screen to put up a simulation of a spaceship flying around. When the spaceship crossed the intersection of the aiming points, you were supposed to hit the Clear button which cleared the screen even while the program was still running. This would fire your "gun" and the game would immediately redraw the screen so there was only a brief blank-out pause. The way the detection worked was that the program would light up one graphics block near the bottom of the screen and would continually monitor it using the POINT function so that it knew when you'd hit the Clear key since Clear would erase the block and POINT would return a zero instead of a one. I figured out that it would be possible in theory to detect 5 different keys using this method, although I never used it in any actual program. (Backspace, Space, Enter, Clear and Up-Arrow) In practice though, detecting the keys would probably have been unreliable if any screen activity was going on at the same time other than using POKE, since the detection depended on the cursor remaining in one place all of the time. In spite of its failings, the TRS-80 was my introduction to home computers and I still feel a minor soft spot in my heart for it.
@Robert08010
@Robert08010 3 күн бұрын
I thought so. When the keyboard didn't let him answer "4", he could have answered "2*2" and it would have worked!! Another little known oddity was in reply to an input. If it expected a number but you answered with a word instead, it assumed you meant the variable beginning with that letter. So if it was Input A, and I answered "Robert", then A would be assigned the value of the variable R. Weird, huh? Also, Level I basic had no peek or poke commands. That was in Level II. Level II also introduced "Inkey$" which was able to read the last key pressed even before hitting the ENTER key.

This was one of the 1st computers my school got in around 1981. At the time I was learning electronics at BOCES so, my school asked me to upgrade the ram in about 5 or 6 of the TRS-80's from 4K to 16K. I remember sitting in a room with the computers in front of me, all taken apart and a pile of (DIP) ram memory chips sitting at my side. I had an anti-static bracelet strapped on my wrist and I was wearing anti-static gloves so that I would not damage the chips. I remember other kids in school walking past the classroom staring in to see what I was doing. They thought that I was a scientist or something! Wow!! what a RUSH that was.

What sparked my interest in programming is that we had a version of Star Trek (I think it was called "G-Trek") and my dad got pretty good at playing so. Since it was written in basic, he simply upped the number of Klingons and I was amazed. How was that possible!?!? And when he wrote a program to help my brother calculate the size of a circle and it was never wrong, I knew I had to learn about this stuff.

@9:23 If it had worked correctly, it would not have scrolled down the screen. Print At should have made it print at the same location over and over. But I don't think "Print At" is apart of the Level II basic. At least "Print At" doesn't appear in the language reference I checked. Also notice on the top line left of the "H : M : S", there is a zero. That confirms my suspicion. Level II Basic didn't recognize At as a command so it printed the value of the variable "A" instead.

He said that Apple didn't have to worry about the FCC requirements with the first Apple II models, because they didn't have an RF modulator, and Apple officially classified them as "office equipment." Interesting about Meteor Mission. I've seen a couple games like this on the Atari 8-bit.

Kinda OT, but a few of my C64 cassette games also had the loading timer. One of them was the Hit Squad budget rerelease of Wizball, and the reason was 'cause between the original release and this rerelease, they'd managed to develop faster loading routines and the original game had a very intricate loading sequence with music and 320x200, full colour loading screen, but unfortunately it ran too long for the new loader, so they replaced it with a countdown timer.

You actually keyed in the program incorrectly, because you are using a Level II machine, and the manual you're using is for the Level I, which I can tell because you got the "MEMORY SIZE" prompt when you booted it up. The Level II computer requires you to use the "@" symbol rather than the word "AT." The 0 you see on the left side of each line is because it thinks that "AT" is a variable that isn't set to anything. If you key it in correctly for the Level II using the "@" sign, everything will print in the same spot on the screen, so you'll only see one line of output that keeps changing.

All of the computer companies at this time were unbelievably conservative with their tape transfer routines. The Starpath Supercharger was a 'games on cassette; device for the 2600. It had 6k of RAM and most of the games were around 6k. It could load these 6k programs in under 10 seconds. I have a newer clone of the supercharger that has 64k and works with all Atari cartridges without extra hardware, which basically means pitfall 2 won't work. There are modern 2600 games much larger. There's one I play that's 32k. It loads in under 30 seconds. it uses the same exact load routine as the supercharger which was made in like 1982. So it's not like there is a bunch of new hardware in it that wasn't available in the 80s. The main problem of cassettes is cheap cassettes have "drop outs" which would cause a failure. But it would fail at almost any speed. Slowing it down doesn't help with that. Commodore takes things even further by writing the whole thing twice. AND Commodore had full control over what cassette recorder would be used because most CBM machines only worked with the dataset and could not use a regular old tape recorder.

"And it actually _broke_ the computer." Wow, how would just entering a number that it couldn't handle _destroy_ one or more of its chips?

Model I Level II. The Level I only had 4k ram and a version of basic that didn't have very good error codes. It would literally say, "What?", "How?", or "Sorry". lol Not very helpful! The Level II was upgraded to 16k and the error messages were much more helpful. I also liked using "?" as print. I also never noticed a problem with the keyboard.

"What?" = Syntax error. "Sorry" = Out of memory. "How?" = Everything else. Just in case someone wanted to know. 😃

Yes, that was a common problem where you plugged the power into the video socket and fried your video chips.

Yeah crt monitors have a great big electro magnet coil around the tube (scanning yoke assembly) which moves the electron beam across the screen. Great for erasing disks.

Wow, how silly that this computer asks _you_ for how much memory it has instead of being able to detect and _tell_ you like the Commodore 8-bit ones do.
@Sashazur
@Sashazur 10 ай бұрын
I think that was optional. If you just hit enter it would give you the maximum available, but you could enter a number to reserve some memory so it wouldn’t all be used by BASIC.

Haha, the graphics on this computer -- at least that I've seen so far in this video -- are worse than if you wrote a PETSCII version of it for Commodore 8-Bs!

Yeah it had very primitive graphics. But the PET computer that was available at the same time had a keyboard that was like something from a 70s supermarket cash register!

The lack of color makes it very hard for people used to color to adjust to. Basically, the opposite of American society.

Foiled, huh? You do realize that's a foam and foil keyboard you're playing on... There are rebuild kits for those being produced by retro makers. A good repair how-to is at: kzbin.info/www/bejne/r360moNojdWgos0
