A troubleshooting document that nostr:npub19a8tdmlwgk7jhrwzttrqdtcfe8t27lzh90umlwmrl3xtdfvtsnwsw7lsy2 shared with me mentions using the service mode to peek at some memory locations for clues as to which chip on the 512k card is at fault.

Will need to look at this later. #AppleLisaClone #RetroComputing https://files.mastodon.social/media_attachments/files/111/139/205/209/811/251/original/a9ccf1142007b5ad.jpeg
