Why did Steve Jobs have to be such a jerk when it came to cooling fans? Most of the issues with these things are the result of overheating leading to parts failing. 

It screams of power supply issues. You have no way to say the PSU is in good condition until you are positive the voltage rails are good under load and there is no excessive curren…

I had a similar problem with a /// that went away when reseating (and pushing down) the RAM daugtherboard and all its RAM chips.

True Techknight. But such areas are not always written unless a virus hits the system. The directories are a weak point as they are constantly updated with every file write. but th…

When in doubt, check voltages. If those are OK and stable, then next thing is system RAM. 

I recently bought an Apple /// (256k model), Monitor ///, Disk /// external drive, manuals, and software. All of the units are cosmetically in amazing condition (no yellowing, no k…

Here is the problem with bad blocks in flash. Any flash memory that has a block that is bad, will be corrupt with no chance of error recovery or anything. its just corrupt, marked,…

I've had this setup for about 5 months. I got the Compact Flash card from ebay. It's Amicore brand. This is what it looks like.

It's worth investing in industrial Compact Flash units. They're far more reliable.

SRAM cards in CF format would be great. Too bad they only come in PCMCIA format. But would it solve some problems with CFs? I'm not pointing a finger of blame to anyone here, SSDS…

the compact flash card is starting to go bad.  I have 3 compact flash cards myself, and they are riddled with nothing but problems. They really arnt designed for what we are putti…

About 9 days ago, my 1400cs froze while I was using it so I restarted it and it would no longer boot. I booted off the OS 9 CD and it offered to initialize the disk. I declined and…

More info: A quick google turned up this. Crazy detailed with some compatibility charts linked. It looks like the most common problem you might run into when swapping manufactures …

thanks G!!!! So: Apple IIe Apple IIc (Early - Mid production) — late models with 4464 chips, do not work with 4164's Macintosh 128k C 64 - (Early - Mid production) — late mode…

So far as I know the chips used in the Apple IIe/c and Mac 128k are completely bog-standard 4164s so you shouldn't really need a cross-reference table; IE, searching for "4164 DRAM…

seems like the ram with the apple logo on them are the worst…. in the 128k's

Good info! I have more than a few Apple II parts laying around - and a couple 128k boards I would like to bring back to 128k, even if there is no Apple logo on the RAM.

thanks NJ!!!! ok well add c64 and c128 to the list Apple IIc Macintosh I28k C 64 C 128 any more?

THe IIgs memory expansion card takes higher density chips. http://support.apple.com/kb/TA37852?viewlocale=en_US

sorry to bring this thread back up…. but he has a great cross reference table there. so the Apple IIc and the Macintosh 128k used the same memory chips? Any other Mac or Apple p…

Hi All, I have some time this holiday weekend to revisit some of my vintage Mac projects. Since I posted this I have acquired a IIsi ROM and I am still getting the same error sho…

Excellent site; I'll go through my Mac archives and submit any other obscure drivers I have.

Thanks for that, noidentity. Might I suggest also offering them to the Mac Driver Museum?
