Macintosh Classic (II) Analogboard recreation

This is a tested and working analog board recreation of the Macintosh Classic II analog board (820-0525-A). The provided files are licensed under CC-BY-NC-SA - they are NOT intended for commercial use

General

This is a 1-1 reproduction of the Classic II analog board 820-0525-A / 630-0525, "late" revision.

Yoke types

Somewhere during the development of the Classic II Apple changed the CRT yoke type. There are two different yokes which were used during that time, and they are not interchangeable. This replica is using the B-TYPE yoke, which is the right one in this photo. Though It may be possible to interchange the entire yoke on the CRT, but i have not test this.

Board

This board can be produced with 1.6MM thickness. ENIG Surface finish is advised due to slot copper peeling on HASL finish.

240V/110V

The board is capable of handling 110V and 240V. If you want to modify a Mac Classic from 110v to 240v (or vice versa) use the tables. *Please note that I did not test the 110V setup

This is a BOM for the 820-0525-A / 630-0525, "late" revision board. Although I have done my utmost to ensure an accurate list, I cannot rule out that there are errors in the BOM. Use at your own risk
