If I'd come across this in 1986, it would have ticked every obsessive box; I'd have sat at my Atari for hour upon hour grabbing those images! It has just the right amount each of technology, electronics, programming, even meteorology, to fuel my fascination, and is delivered at just the right rate to build anticipation on what might be received! I'm surprised these signals are still available. Thanks for the video.

It was fun seeing you run WriteNow. I worked on later versions at T|Maker for a couple of years, starting around 1988. It was a big deal when we decided to require machines with Mac Plus ROMs so that we could use hierarchical menus. Also, adding color app/document icons meant significantly increasing the size of the application, which was almost entirely written in 68K assembly that had been painstakingly optimized for size and speed. One of the engineers jokingly complained that he had just spent days removing a few hundred bytes, only to have it swamped by the addition of color icons. It was my understanding that NeXT was also shipping it on NeXTSTEP at the same time. I worked a bit with John D. Anderson, mentioned in the About Box you showed, who was at NeXT.

DO NOT adjust the display size !!!! The Atari SM124 monitor screen is set up for WYSIWYG, which is perfect for desktop publishing. The Atari SM124 is a monochrome VGA monitor. They were also used with the Atari PCs. Standard VGA is 640 by 480. The Atari ST computers high res mode is 640 by 400. This is the reason for the larger black bars on top and bottom of the screen. When you adjust the screen size, you not only lose the WYSIWYG image, you also distort the picture by stretching it. Only stupid people adjust an Atari SM124 monitors screen size. 🤔

Great video, very useful info. It is worth mentioning the SM124 has that small screen size due to the screen being set up to have a specific DPI (dots per inch) amount (which iirc was 72dpi, the same as a Mac Plus/ 512k etc). This was useful for DTP work as it was directly translatable allowing accurate depictions on screen and in print. I think GDOS also expects this. Nowadays the extra screen real estate is more useful I would think :)

How many capacitors were bad? Did you test them after removing? Looks like it is another case of recappacide or do what the internet says (change the caps) and you would be fine, then it turns out to be something completely different
@backroomboy44203 ай бұрын
Thank you for assessment and insight. I tested every one from both the neck and pav boards. Other than the 400V cap on the PAV, not one tested as good (though apart from one, all tested good on the DCB). As I said in the video, some were marginal but for the price of a cap, and given the pain this machine is to strip and rebuild, it's certainly easier simply to recap while it's apart. And now, forgive me while I go back to the internet for further instructions... :)
@michvod3 ай бұрын
@@backroomboy4420 Interesting. I usually test them with an ESR meter. Bad ones would have higher than normal ESR. Anyways I prefer to first make it work, then do a recap. Dealing with old tube radios, this usually saves my ass if something really major is at fault, before I spend 4-6 hours recapping it. Like having defective transformer or some coil... Most of the times bad capacitors will not prevent it from working, it will just make it work badly

So I went ahead and replaced all capacitors on board except the big one which seems to be in a good condition. I found some corroded resistors which I checked and cleaned and replaced a broken one. I believe the board I worked on is the next revision. There is no C922 capacitor and found C937 is 33uf 50v rated. Since I have already ordered 35v ones I just put that one in. Did not explode 😉 So far so good . Green iMac G3 450 is back on duty !

Hello, many thanks for the very informative video. I have slot load G3 450Mhz model and recently it started to load image on the screen very slowly. When warmed up it continued to work normal. The last few days it get worsened. It attempts boot in a continuous loop and sometimes manages to load OS with screen briefly on and then off. I'm checking PAV and see on C947 16v47uf cap base brownish oily stain. Is it possible that a tiny cap can make all this problems? or maybe the Flyback transformer could be the main cause? I'm considering if I'll go to all of PAV overhaul time/cost process. Cheers😀

You're welcome and thank you for watching. Its difficult to be certain without a schematic, but your problem sounds very like a capacitor issue and I'd be surprised if it wasn't more than one which needs to be replaced. The majority of those on my PAV board were neither bulging nor leaking but almost all registered at best a marginal ESR. Good luck!

This was the first computer I bought new. Why? I was young and didn't have a lot of money and this offered a pretty good value. Full-sized keyboard. The two 720K floppies. A screen. Software bundle. Case. And the 2400 bps modem. And 640k ram. For me to buy all this functionality in the day in an IBM or compatible, I'd have to spend a lot more. I'd have to buy a monitor, spend to upgrade to 640k ram, upgrade to a 2400 bps modem and buy software. So for me, it was a good value. I still have it. I bought a second one that I have played with. I removed the clock chip and put in a RTC. I build an expansion board for the back and can run/boot from a Compact Flash card. And I have screen to run color CGA by replacing the mono LCD SuperTwist.

I'm getting it to show my HDMI connected display, but it's very shaky and colours are wrong; Two questions, the 1k resistor is shown on your video between 18 & 19, whereas on the pinout, I see the resistor mentioned to be going to the inverter cable; Are there 2 resistors or did i misunderstand the pin-out for the HDMI?
@backroomboy44206 ай бұрын
Thank you! Blimey, it's a long time since I did this but wracking my brain to try to remember... there's a 1K resistor between pins 18 (edid +5v, purple wire) and 19 (hot plug detect) on the HDMI plug/socket and a 1K resistor on the inverter's green 5v wire which sets screen brightness (IIRC). Picture instability is more likely to be a poor connection on your HDMI breakout (if that's what you used). Try it and let us know what happens here in the comments. Good luck!

Sincerely enjoyed this video - nicely done. I've been on the hunt for one of these for a few years and finally, got lucky enough to snag one off of ebay. Its a new old stock example, so thats the good news. The bad news is, it's not working. I do hear a faint high pitched sound when I turn it on, and the screen does flash when I remove the power. I'm wondering if what you experienced is related to the cmos battery being old and exhausted, and possibly with power on the board for a while it somehow affects it? Or would no power feed into the cmos battery? Its a desperate wish, i don't want to disassemble it. Will leave it with batteries for a couple of days and think positive thoughts :) Thanks again for the video. Have subscribed.

This made the Gadgets by Small products superior to the Aladin in my estimation.
