First Post (and the start of my IIci journey)

Hi everyone!

I am new here and to 68K Macs (my first Mac ever was already a PPC OSX), but I'm sort okay at Commodore and Amiga restoration.

I recently heard that a recycling center near me had 9 pallets of Vintage Apple stuff they were selling out prior to destroying what wasn't sold.

Because of work, I wasn't able to show up until the end, so there was little of use left. I "liberated" two Mac IIci units (and an external floppy drive), with network cards and what appeared to be full RAM banks.

Both were water damaged and with oxide issues, but one was in almost good shape. I have no keyboards or mice (getting them).

Insects, including an entire wasp, cobwebs, you name it, it had it. They were in horrible shape. One board and PSU, after I opened, was sadly too far gone. Cleaning it with vinegar carefully, it ended up dislodging the UK14 RTC chip - the legs were actually completely gone under the green acid and the oxide. Very sad.

But the other board works after cleaning, and battery has not leaked (though caps by sound area are probably dead because it's a quiet Mac).

I have a mouse but it doesn't work (I don't know if it's the ADB ports or the board because I have no other units to test).

By switching components, I was able to get it to boot to a sub-VGA resolution on an older monitor with an adapter. What a rush to get it to boot completely!

So now my dead pieces are:

A Main board stocked with 8Mb, one 320Mb HD (I may be able to rescue it, who knows), A cache card (ironically, the one that worked was on the oxidized one), and maybe a few Nubus NICs (I have three of them, two from oxy-dead, one from this one).

Also I need to test RAM as soon as I can get a working keyboard because I have a bunch of RAM sticks in unknown state. Floppy drive motors seem dead (won't bring in the disk, but once disk is in it seems to read okay, at least enough to know what I put in is "not a Macintosh disk"). The one PSU I have clicks like it's ready to die.

But surely working I have one clean Mac IIci that is humming nicely, with all lights and buttons and all 4 rubber feet working and pushable and rubbery, and importantly, clean.

Now that it's "burning in", the PSU seems happier. I will probably need a different one though. I don't know how to properly repair PSUs.

Not bad for a landfill save...

REMOVE THE BATTERIES!!

Clean out the board gently with some IPA. that battery residue may have loosen up some of the traces.

Otherwise, excellent job on rescuing two Macs! You can run the IIci without the Cache Card, all it does is increase the CPU Speed some 15%.

See if you can find some 16MB RAM sticks to get 64MB on 4 slots. If you go all the way to 128MB, the RAM Test will take 20 minutes to do - LOL!  A DayStar Accellerator would be nice if you can find one. They are rare and expensive; come in 33 or 50 MHz 040 CPUs or 33MHz 030 CPU; they go on the PDS Slot that Cache Card is in.

As I remember, you can run  OS 7.5.5 and 7.6.1. There is a hack for running OS 8.0 to run on 030 machines, I forget where though. Scour the internet for that. I recommend using a PPC/68K FAT checker/remover program on the programs you have on system, but archive the originals! Remove the PPC Codes from the apps on the machines using the checker/remover program, they will run quicker and take up a lot less space in RAM and on the HD! It makes a BIG Difference!!!

Wow, I had no idea it would take that long!  Are you serious?  How long would it take with 64MB?

I have 128MB in my IIfx and it doesn't take longer than a minute or two to boot.

A few minutes for 64MB, a bit more than 5 minutes. BMOW has a few videos on Youtube demonstrating this.
128MB on your IIfx? I'm Jealous! I only have 16MB on mine - LOL!
