Macintosh 512k sad Mac error help

[TimTheEnchanter]

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.

This is a Rom related fault code

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...

Because the ROMs are socketed, the solution could be as simple as reseating them.

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.

Not sure, as this is something i have never done myself, but can those be duplicated using an Eprom Burner ?

I think 27512 Eproms can be used.
