JDW | VGA mod for the Macintosh Color Classic (640x480) & Doping Mac @JDW- | Uploaded February 2022 | Updated October 2024, 1 hour ago.
I examine 3 ways to get 640x480 on the Color Classic, then implement the VGA Mod. Before/After screens shown. VGA lets you to use software that won't work on 512x384.

🙏 HUMBLE THANKS to Kay Koba (Kero's Mac Mods) whose advice I cherish. Kay's Blog articles: ameblo.jp/keroxiee1016/entrylist.html

🤓 NOT MENTIONED IN MY VIDEO
• You must adjust the CC CRT when switching between 640x480 & 800x600 because it's not Multi-sync.
• There is no "motherboard mod" to get 640x480. You can change Line Sense on the motherboard or ribbon cable but not Horizontal Deflection Voltage. That's why we make Line Sense & Deflection Voltage changes on the Analog Board.
• The logic board "resistor mod" mentioned at "powercc" is only used to get the LC550 or LC575 motherboards to work with the stock CC resolution of 512x384 instead of a software solution: powercc.org/mystic
• Like 512x384? A software solution may be best. After doing the Mystic upgrade, I used a ResEdit-hacked System Enabler 065 v1.1 in System 7.1 to get it to work at 512x384: bit.ly/3HhyPtU
• System files in 7.5.x, 7.6.x & OS 8.x require ResEdit hacks for the LC575 Mystic motherboard to work at 512x384 (not needed if you do a 640x480 VGA hardware upgrade as shown in my video): bit.ly/3AMcTVB
• Stronger Analog Board possible? Yes! The LC575 Analog Board can be cut to fit inside a CC. It's more robust & durable than the stock CC board. METHOD #1 or METHOD #3 (described in my video) can be used with the LC575 Analog board. But it's a lot of work! Kay Koba's Blog provides details, and note the Flyback transformer from CC Analog board is also required: amba.to/3obq7G4
