I use a Macintosh Plus since 1993, and it still run today, without any repair or recap !
Now I retrobright old Mac I found.
I currently have the Macintosh Plus (operational), Mac LC (operational), Mac LC 475 (Nok) and Mac LC 630 (operational).
I own too some original artifacts, especially a Farallon EtherMac SCSI, to connect the Macintosh Plus (or every other Mac) to the home Ethernet Network.
