OF00064 Sad Mac On Macintosh M0001

Hello!

I recently bought a M0001 Macintosh off craigslist with no boot disk, so I bought one online from a site that makes them on demand. Trying either system 1.1 or 3.2 brings me to a Sad Mac screen with the code OF00064 under it, after showing the regular mac for a second or two, Ive looked online everywhere I can find the error code referenced and found the error is most likely software related but the Disk came from a good source, I'm not sure what to do from here, is it possible that there could be a hardware problem?

Also, I'm not sure if it was upgraded to 512k but the instruction manual has "512k" written on it. and the disk drive has a red light inside, from what I read that means its a 400K disk drive.

I also do NOT have a HD20 or External Disk Drive.

I also found this online:
http://www.cafr.ebay.ca/itm/Early-First-Model-Apple-Macintosh-Mac-128k-M0001-Vintage-Computer-1984-/321298675766
This person on ebay stated they had the same error on the internal drive but the disk worked on their external drive.

If anyone has any help I would respect it!

Hi poopdawg,

I had the same problem with my M0001. I bought an external Apple 3.5 disk drive and booted just fine So the culprit is obviously the internal 400k drive. I disassembled mine and cleaned the 400k drive and works perfect ever since. Smile

Sad Mac codes are explained here: http://web.archive.org/web/20090617213904/http://support.apple.com/kb/TA46376?viewlocale=en_US

I agree with snazzify that cleaning the drive might solve the problem. Usually the grease isn't doing its intended job anymore after all these years and instead blocks proper movement of the parts...
