| Macintosh 512k sad Mac error help | |
| Posted by: TimTheEnchanter on 2019-12-20 17:53:34 I had a good look through the “Sad Mac” error codes web page and couldn’t decipher the code. On startup every time I get a 01C000 code and I have no drive drive activity despite having a good boot disk (verified on another machine) if anyone can tell me what this means that would be great! Thanks. | |

| Posted by: BadGoldEagle on 2019-12-21 03:52:36 What Bibilit said + If your other machine is a 128k, another 512k or a Plus, you can switch around the ROMs to troubleshoot. Be sure not to put them on backwards... | |

| Posted by: TimTheEnchanter on 2019-12-21 16:12:20 I’ve swapped the ROM chips and it boots now but where do I find ROM chips that I can buy for this Mac? I’ve looked on eBay and have found some that look fairly sketchy and would prefer some that are of the same type or that someone can vouch for. | |

| Posted by: dochilli on 2019-12-23 11:30:36 I think 27512 Eproms can be used. | |
