The owner till auction in 2020 was from Chicago. Maybe he bought the Apple-1 in the 90's.
It has the original box signed by Woz at a UCLA alumni event with photo documentation of Woz with the box.

Equipment

Original Apple Cassette Interface.(first batch SCC), original box, Operation manual, ACI manual. Panasonic cassette recorder, Sanyo VM4092 monitor from November 1976. Datanetics keyboard from 1977 in a wooden box. Power supply from 1976 but transformer without any date code. The internal wiring of the power supply was secured in 2020 (it was only taped).


State

Some restoration work was done in 2020 by Corey Cohen. The power cord was replaced due to bad condition of the old one. Like some NTI boards a part of the coating above the breadboard is gone. Probably there was a sticker removed. Some boards have a sticker at this location.
