Hello,

I'm trying to resurrect an Apple /// 256k (non-plus) but I'm having a
bit of time with it. It starts up, hits the disk drive and then just
halts. Sometimes I can get some garbage on the screen. If I don't put
a disk in it'll just list "retry".

I've gone through most of the chips to see if anything was amiss. One
was quite corroded and a pin broke off when I removed it. I re-
soldered the pin back on and it seemed to make some progress with some
more garbage on the screen (well different) but I'm still not there.
The chip is labeled on the motherboard with an Apple part number of
341-0030.

Checked the power supply and it's just fine. It's amazingly clean as
well. No doubt from being sealed in that vault of a box.

I'm thinking that the damaged chip might have been one of the roms.

Anyone have a set of ROM images for the Apple ///? Haven't been able
to turn much up in google.

Thanks!

I probably have a couple Apple /// motherboards in my warehouse. I
know I have a number of ///+ motherboards.

That would be cool to check out. Can you drop me a note one what you
are looking
to get for one?

Thanks!

"retry" is hopeful. That means the ROM ran through the memory
diagnostics (and passed), and tried to boot from the disk drive.
There isn't an awful lot more on the ROM to begin with. Do you get
into the monitor with Ctrl-OpenApple-Reset?

You can see the Apple /// ROM on ftp.apple.asimov.net:
ftp://ftp.apple.asimov.net/pub/apple_II/emulators/rom_images/
and look for Apple3ROM.bin. But I'm not convinced that your machine
is misbehaving yet. What are you trying to boot? Are you sure that
your disk has SOS on it? (And that the floppy itself is good?)

Hello,

Ahhh ha!

The solder didn't hold on the pin I "fixed". After re-applying I'm
into the system. Just booted up AppleWriter ///.

Very cool!

Thanks for all the help!

This sounds like you are starting out right. In the beginning, the
Apple /// had a *lot* of problems... ;-)

That seems to be an emulator format. How do I extract the actual
ROM content from the file (without an Apple /// emulator)?

These MAME ROMs are dumped via burners where possible:

But this one is not a ROM image--it is prefixed with a header
containing ROMMSARA among other things...and it's 6912 bytes long.

Heck of a history with this thing.

Seems to working just fine. Not much software for it!

Best,

Certainly nothing like the Apple II, that's for sure. Have you seen
the Washington Apple PI's disk collection?

The ROMs at the "slor" URL are ready-to-burn. Actually, the same
Apple3.zip is in the asimov rom_images directory.

You're correct that the Apple3ROM.bin mentioned above is something
else ... if you skip the first 0x80 bytes, the next 0x1000 bytes are
the ROM. The remainder has strings like "DataViz" and "Appleworks DB"
so I don't know (or care ;-) what kind of file it is.

Cheers,
Nick.

Thanks much!
