Apple ][+ gravely ill - seeking assistance :(

N N Thayer

From: N.N..Thayer@familynet-international.net

Ugh, it's like a stake through my heart. My trusty Apple ][+, the one I've had
practically since I was born, that I've used for endless recreation and to rip
who knows how many disk images, has decided to check out. I'm hoping that
whatever it was is easily replaceable and didn't take anything else down with
it. I now direct my cry for help to csa2.

Here were the symptoms in sequence. The powerups were spaced several seconds
apart.

1. Power on. Beep, floppy drive (Disk ][) does not initialize. Power off.
2. Power on. Beep, drive does not initialize. Power off. 3. Power on. Beep,
drive does not initialize. Ctrl-Reset to prompt, PR#6. Drive initializes.
Power off. 4. Power on. Beep, drive initializes. Power off. 5. Power on.
Beep, drive initializes, disk is read. Text menu appears and shows display
corruption. Some letters are replaced with random symbols. The corruption is
not static: new symbols slowly appear and change as I watch. Reset produces an
abbreviated beep, perhaps half of its usual length. Power off.

(a few minutes pass)

6. Power on. Similar abbreviated beep, screen full of garbage characters,
drive does not initialize. No response to reset. Power off.
7. Subsequent attempts produce results identical to #6 even with all cards
removed, including Language Card.

I haven't done any further testing yet other than checking chip seating.
Nothing smells blown, though I know it must be otherwise. Right now I'm hoping
it's just the power supply, which would be easy enough to rectify, assuming
nothing else has been affected. I am so very open to suggestions.

There's nothing you can do about the repeats.

The BBS sysop has a configuration problem and apparently doesn't
realize he's echoing posts... ;-(

BTW, just try replacing memory chips--or, if you're lucky, try
bending the pins in a bit on a good memory chip and "piggybacking"
it on each memory chip in turn to see if you can get it working.

The one you piggybacked when it worked is the bad one.

(This doesn't always work, depending on the chip failure mode,
but when it does, it saves a lot of time. ;-)

There are, of course, other possibilities, but trying the most
likely things first makes most sense.

I actually have a IIc with a piggybacked memory chip.
Rather than disassemble the entire machine, I simply
removed the +5v pin from the bad chip, and soldered
the good chip on top, so that the power only reaches the
good working chip on top. I don't recommend this for
all applications, but it was a good solution for me. )))
