What’s the transformer/yoke-coil specs on the Macintosh XL Screen Kit? I’m trying to make a kit for my XL but can’t find anyone selling the transformer (or really any of the parts besides the main two roms). | Posted by: SigmaJames on 2025-07-29 21:12:39
DIY instructions for the Lisa square pixel screen mod transformer are here, I think...

As well as the pair of Rev 3A 2764 EPROMs for the CPU Board, and the transformer (which isn't strictly necessary but is usually required to be able to adjust the video board so the raster fits on the CRT), you'll also need the square pixel version of the "Video PROM" for the CPU Board. Unlike the other PROM versions, this one doesn't have a unique serial number, so all the screen mod video proms are the same.
Then for software, MacWorks XL 3.0 comes in two versions, one for square pixels, one for rectangular pixels. MacWorks Plus and MW+II are pixel agnostic. All of the pre-MacWorks XL software requires the rectangular pixels, at least until the Office System is recompiled with suitable modifications. | | 1 |
