I've recently been offered to buy a 1984 Macintosh but it has the sad Mac face with the error code 01E000, what is it and is it easy to fix? Here is the description from the owner... "Apple Macintosh 1984 in good condition (Model No: M001WP 512K and serial no: F42709LM0001P. Height: 33 cm. Width: 24cm. Depth: 26cm. Produces floppy disk sad face icon onscreen when powered up with no. 01E000 under it. External Drive 800K (1985) Model No. MO131. Serial No: Y5COMMJ.

" Is it worth it for around about $70USD? EDIT: Also is this the model with the signatures inside the case? Thanks.
