I worked for an Apple dealership from 1979 to 1989. The biggest problem with the Apple /// was that they used sub-par IC sockets. During shipping, IC chips would start working their way out of the sockets. The remedy was to re-seat the IC chips, much as you have done. After that, it was a fine machine. I still use the phrase, "I'm okay, machine status normal."
@GaryCameron7807 жыл бұрын
Somewhere I learned that the Apple /// RAM would also start to crawl out of the sockets as the machine heated up. Rumor has it the fix for this would be to power off, lift the front of the machine a bit and drop it.
@itsallanexperiment93917 жыл бұрын
The socket issue was caused by contact fretting due to dissimilar metals between the chip leads and the socket material. Chips didn't just 'get loose'. Apple could've solved the issue by getting rid of the sockets entirely (the cheapest way) or using gold plated sockets - not Apple's stye. Whoever was in Apple Engineering at the time desperately needed re-boot. Also, overheating with these computers is a myth. Remember folks, these were 6502 computers. This one slightly over-clocked.

For those who own machines with 12V RAM chips, there is a way to get them going with 5V RAM chips: 1. Firstly, grab your new memory chip, a TO-92 7805 voltage regulator, a 100nF 50V ceramic cap and, more importantly, a cup of coffee; 2. *Lift the chip's VCC pin* and solder it to the *pin 3 of the voltage regulator* and to *one of the pins of the capacitor;* 3. Solder a piece of wire *from the GND pin of the chip* (without lifting it), to *pin 2 of the voltage regulator* and to *the other pin of the cap;* 4. Bend *pin 1 of the voltage regulator,* in a way as to make it fit into *the original VCC pin of the socket;* 5. Glue both the cap and the regulator onto the chip's back, with epoxy resin (not really critical); 6. IT'S DONE! P.S.: Prevously, I said you would need a 7806 regulator. Sorry! You'll need a *7805.* Actually, if you were to install a 7806, you'd cause an SCR Latchup in the chip, and this would release it's magic smoke pretty quickly. P.S. 2: Please check your new chip's pinout, to ensure both the old and the new chip are pin-by-pin compatible.

The reason you'd use a linear regulator over a buck regulator is because of noise. Linear regulators create a very clean output which requires minimal filtering. Buck regulators on the other than are RF blasters and produce very noisy output, which requires complex filtering that usually isn't present on readymade buck modules. The interference a buck regulator creates can cause erratic behavior in circuits, especially older low-frequency circuits. It's the reason why audio gear still uses linear supplies, even though it makes them large and heavy.

I worked for an Apple dealer in the Detroit area back in the late 70s through about 1985. I was also a member of a local Apple computer user group and back around 1980 or so Apple had a special get together in Chicago as an outreach to the user groups. A couple of friends and I went to the meeting and saw Steve Jobs and Steve Wozniak there. Can’t remember for sure now but I think the other speaker from Apple was Mark Markkula? In any case he was talking about the problems they were currently having with the Apple /// and he said the problem was “Workers who didn't know the difference between this socket and that one, and you can’t explain it because they don’t speak English!”. Got a lot of laughs from the audience, but obviously was a different time then.

That advice was because the /// used a tin socket between the motherboard and RAM board, which would start corroding basically the second the machine was assembled.

We were excited about it until we actually set up the demo unit and started experiencing glitches from the moment we powered it on. Things got really bad after it began heating up. It seems that many of the problems were caused by overheating and poorlly seated chips, and after opening the unit and pressing down on the chips, we could get it to work. But after experiencing these initial problems, I never had to heart to recommend it to any customers. I left the shortly after - but not because of the Apple. I was offered a better job.

No. These need to be X2 rated caps, designed to withstand 2.5 kV peak and approved by UL / ENEC / etc.. Traditionally they are special metallized paper caps, but metallized propropylene seems to be working well, too. You generally get what you pay for with these, and comparing dimensions you'll generally find that parts from a reputable brand (WIMA etc.) are bigger than some others, implying thicker dielectric and thus better peak voltage handling and slower aging. Incidentally, Yamaha also recalled some of their early-'80s HiFi amps just a few years ago due to the very same Rifa caps (though really, if I had something like an A-960 II I'd much rather swap out the cap and keep it, those are nice amps). They're also pop-ular replacement candidates in Dual turntables.

One of the freaky things about the Apple /// was that it had custom circuitry external to the 6502 that added additional addressing modes (using unused bit patterns for instructions) so that the processor could actually access 24 bits worth of address space directly, without needing to bank switch like most other Apple IIs. (The 65816 used in the IIGS actually could address 24 bits of address space directly, by multiplexing the upper 8 bits onto the data bus lines.)

But in the case of that MacBook it's like a pretty much useless fan that can't even get enough hot air out of the case at max rpm. And let's not forget a "heat gun" MacBook where again heatsink wasn't enough so the fan was blowing out really hot air but it was actually going to display bezel which was glued with some glue which wasn't too resistant to heat. It looked like purposefully designed bezel self-destruct mechanism.

Apple had problems with the original RAM sockets being too tight, and bending the pins when they inserted the RAM chips. They replaced them with lower insertion pressure sockets, but the chips tended to work part way out of the sockets during transportation. The official solution was to place the computer on a flat, hard surface, unpowered, lift it six inches, and drop it to seat the chips. It actually worked in many cases.

The 12 volt ram chips in the smaller sizes were pin compatible with the 5v only ones. The extra +12 and -5 power pins were NC on the 5 volt parts. IIRC only the 4k and 16k parts were made in the 3 voltage type. the 16K parts 86'ed the CS pin, and used it as A6 (the lack of RAS or CAS was used as a CS). On the 64K and 256K parts, the unused +12 and -5 pins became A7 and A8. SO... I think that the 5v only 4K and 16K parts will work in a board designed for 12v chips, BUT it might be safer to not insert the NC pins into the sockets, just in case....

Often you can technically use the device normally while the smoke is pouring out, but of course no one does this and I really don't recommend it. They were designed to fail in this "relatively benign" way (there is usually no collateral damage) if they ever fail. Nevertheless, if you encounter those .. change them.

Im surprised to hear how few of the 3s were sold... i guess i was lucky. Even tho i remember very little about them, other than the green and purple colors i recall from various programs they had us run.

I heard that Apple support used to tell people having this RAM issue to lift the computer and drop it on the table. This was supposedly to help chips reseat themselves into the sockets.

Another reason for the aluminum block design. FCC regs. They were softened up somewhat after a fiasco with Texas Instruments which had their computer delayed much to the chagrin of the Texas House rep who complained to the FCC that their shielding standards were too high. Both the Apple III and the first Atari 8-bits used huge aluminum covers to contain RF signals in 1980 and 79 respectively.

The Apple /// also had an interlace kit you could buy, that double the lines on screen which removed the gap between the horizontal lines. The interlace kit didn't work with every monitor as some Apple /// monitors could handle the refresh rate without flicker. I recall checking multiple monitors at the local computer dealer until I found one that worked perfectly well with the Apple /// interlace hardware upgrade. :-) Also, a number of people didn't know that you could turn off the video hardware to increase the CPU clock speed a little.

"Also, a number of people didn't know that you could turn off the video hardware to increase the CPU clock speed a little." That was a pretty common trick on hardware of the day. For example, I know the Commodore 64 could do it, as well as the ZX80/81/TS1000.

@948320z6 жыл бұрын
According to wikipedia, Steve Jobs hated fan noises so neither the Apple III nor the original Macintosh had fans. Both had massive overheating problems as a result.

From the end user point of view the technical problems were a headache for the service company. Most companies who had these most likely had some service agreement given the high price. IMO the 48K design limit for Apple II software was the real problem. The first of a long line of Apple neutering their own products.
@adriansdigitalbasement4 жыл бұрын
Yeah so disappointing. I saw aftermarket came up with solutions to allow the full 64k but it was an entire plug in card -- so clearly Apple really neutered it in hardware.

Apple II emulation was limited by the Apple III designers so it could only emulate a 48K machine because of their marketing decisions. They didn't want the two machines competing against each other. One of the joystick ports used extra pins to control their thermal printer called the silent type printer. It's another reason not to try just any type of joystick or game controller that wasn't made for the Apple III.
@Apple2gs7 жыл бұрын
It's not a software limitation, Apple actually built-in hardware circuity to block RAM access above 48K in Apple II mode. No amount of programming can get around this, you literally must modify the motherboard (to the best of my knowledge, no one ever has). This "crippling" was done purposely to discourage further development and usage of the Apple II. Interestingly Titan released hardware plug-in boards that emulated a full 64K Apple II Plus and (later) a 128K Apple IIe on the Apple III.
@galier27 жыл бұрын
It's probably more difficult than you imagine. It has to emulate the 16 K language card mappings of memory, i.e. 2 4Kbyte block at address $D000-$DFFF and 1 6Kbyte block of RAM at $E000-$F7FF and a 2 Kbyte block at $F800-$FFFF of ROM or RAM, all controlled with soft switch at address $C080-$C08F

My dad had the revised Apple /// that didn't overheat and lose chips. Bought it new. It cost about $7000 back in 1981-ish. I remember the Apple ][ emulation 48k limitation causing some of the newer games that required 64k to not work. A game that used the joystick would not work as the axis would be completely wrong. My dad was a bit of an electronics tinkerer(built a Heathkit TV once) and was able to correct the joystick problem by building an adapter that switched some pins around to make it work. He bought the Apple Pascal compiler and spent most of his time writing programs on it.

Funny how your Weller soldering station (that's what I'm guessing that thing is) is sort of shaped like a mini Apple /// case. ;) (Incidentally, both seem to have been inspired by the Algol TV set, by Zanuso & Sapper).
