Office desk with Commodore PET, Powerbook, and Macintosh Plus.

On 20 Oct. 2022, City Tech Alumnus Philip Burkhard donated the Macintosh Plus shown above on the right to the Retrocomputing Lab before the original owner junked it! It appears to run, but I don’t have a keyboard or mouse for this model (it was the last pre-ADB Macintosh, so the keyboard uses a 4-pin telephone-like connector and the mouse uses a DE-9 9-pin connector).

Before dropping it off, Philip took the photos below showing that it does power on.
