It would also be a good idea to replace the output side electrolytic capacitors in the power supply. I noticed that at least one of them has a shrunken outer covering which means that it is probably bad (it has over-heated). It's possible but unlikely that all the memory chips are bad, so I would do the power supply first.

The 80 column card is actually a 64kB memory expansion so you get a grand total of 128kB. As far as games are concerned, 99.9% don't need the extra memory. One game that uses 100% of the 128kB is Prince of Persia. To enable 80 column mode, you need to type PR#3 (it makes a call to the firmware of the card installed in slot #3). Typing PR#6 starts the floppy disk card's boot sequence ;)

[@mensaswede4028]

I have an original power supply from a rev 0 Apple 2, 4-digit serial number. The PS almost works, but not quite. The output voltage ramps up nicely when you power it on, but then overshoots the target voltage, causing the digital clamp to kick on, which drains the capacitors to avoid over-voltage, and then rinse and repeat forever. I’ve spent hours troubleshooting this supply because it is so valuable, but every component checks out ok.

The modulator card is just that... an RF modulator for using it with a TV. Apple II didn't have one on the logic board. The slot is only for power and/or a place to mount it. However that last slot is special in that it has a few signals for alternative video cards that the other slots do not, likewise, not all non-video expansion cards work in that slot.

The grommet is 2 pieces, that little loop is supposed to allow you to separate the two, which then makes the diameter of the remainder small enough to slide out easily. Then you don't have to wiggle it out with force. Glad you got it working!

[@chris4470]

Really enjoyed this video thanks. I love older electronics that are built properly - love the alodined aluminium case for the PSU. I'm an electronics/radar technician. Small tip if I could mention regarding soldering (your soldering is excellent), it's best practice to trim your through hole component leads to length before soldering. When soldering, ensure the lead tip has been wetted with solder. This means there is no exposed copper that can then corrode, which is what happens if you trim after soldering. Looking forward to the next video, always interesting, love your attention to detail.

You're being classic Kari with that infinite loop in BASIC! 😀 Much appreciate the dedication to keep the old solder for older boards and RoHs compliant lead-free for new stuff. 👍 Looking forward for part 2 where you replace the rams and restore Apple II to its former glory! Take care now. ♥

[@edgeeffect]

Leaded solder is best... I got paranoid last year and bought about 4 kilos of new-old-stock just to make sure I don't have to spend my old age with nothing but lead-free.

[@johnybitmap2559]

@@edgeeffect Sure, it's easier to solder with.. lower melting temperature (and not even a need for soldering station because of that) and all, but as a rule of thumb - you don't want to pollute everything with lead. That's why keeping lead for already leaded electronics and lead-free for RoHs (and everywhere possible) is a prudent thing to do. Now, not all lead-free solders are made equal. If there's a way to make the melting point akin to rosin core 60-40 leaded solder, I'd definitely go for it. I've seen bismuth addition mentioned as a compromise between leaded and lead-free. Though it's not completely environment friendly, it might be worth checking it out.

[@edgeeffect]

@@johnybitmap2559 Oooh... I don't know about that... I add bismuth to stubborn old joints that I can't shift (as it massively lowers the melting point) and then make sure that I purge all the bismuth from the pad before putting the new component in - as, if the bismuth gets into the joint, it'll make it really brittle. Bismuth is a major ingredient of "chip quick" but I just use a big crystal that my girlfriend got me for my birthday from a hippy shop.

Glad to see a young lady into retro tech.

[@stevewahl5041]

Great to see someone young like you doing work like this and making videos about it! I would strongly suggest you remove and reseat any socketed chips and test again before doing anything else about your RAM problem. Like others have said, there’s a good probability it’s some other part the chips share in common, rather than all chips being bad. And also some ram is working quite well since you got a BASIC prompt, and were able to get your BASIC program running. Video display also indicates good RAM portions. Not likely shorted or stuck data lines. Maybe problems with higher order address lines is possible. Anyway, good luck, and I’m looking forward to the next installment.

Also IF I feel like I should bother to make sure, I don't care how much of a charge they have, I just use a screwdriver to short circuit them. Worst thing that can happen is that the metal on the screw driver gets hot and a minor spark, and I don't keep flammable stuff around when I deal with electronics anywayz. There are situations where I WOULD do more sensible things, but the cro magnon (or as I call it: Pro magnon) method is perfect for this.I just assume my screwdrivers are rated for the current.

We also got this new fangled thing called “the internet.” My life was forever changed at that point. But I’ll never forget that strange little machine called the Mac in the library. I mean we had some old thing (can’t remember what it was called for the life of me) in every classroom that was essentially just a keyboard that plugged into the back of a tv but we had a master system at home and this thing seemed pretty primitive by comparison and basically only used 3.5” floppy’s with educational games on it, although I wish I could remember what it was called it seemed to have less of an impact on me.

Great job what you done so far. The RAM issue I've seen before with an Apple 2 Plus but ended up being in that case one RAM chip was dead shorted causing the rest to look bad. So this was 1980 so I had access to radio shack and local stores to get replacement RAM chips. However the Apple 2 Plus all the RAM was socketed making it easier to repair without any soldering necessary. But in your case I think it's best to as you're planning just replace all the RAM just in case. I'm currently myself working on a restoration channel for a lot of old tech not just computers but guitars amps and other old electronic devices. Planning on recapping my entire Roland JP-8000 synth kind of giving away how old I really am right? It's nice to see that old school restorations being done by much younger people today is so refreshing over all the other crap on KZbin these days.

thanks for the info and yea, I think from what I've also read online socketing and testing with new/and the old chips is my first port of call ... regards age, I never heard of a Roland JP-8000 synth so you could of got a way with that one, as wouldn't of put two and two together lol

I always enjoy watching you work on things. Love your smile. Hopefully you get the computer working. Good luck!

I am a 60yo guy from the midwest US. I am so glad to see someone of your age taking an interest in keeping vintage machines alive. Folks like you are the future of the wonderful old systems. BTW, you have MT ram... it really is not good memory.

We have Apple IIe when we were in school.

I've been using Apple computers since the Mac Classic, 1991. I did use Apple II's in primary school, but they weren't an instant love like the Mac operating system was. It is great to see that these machines are still operable today. I doubt Apple's output from 2025 will be so lucky in 40 years.

LOVE the good old Apple II! Good pick.
