Macintosh Plus repair.

Defect:

  • Mac sad face with error code not readable.

Replaced parts:

  • 2 x ROM (342-0341-B / 342-0342-A) replaced with two EPROM 27C512 (pinout compatible)

Note:

All roms that i have found on the net or sent by friends are not working.
I had to do a dump of the Rom of my Macintosh Plus and at this point everything has worked immediately.
