Uploaded June 2021 | Updated September 2026, 2 weeks ago
I show how a Dell E1715Sc 17" VGA Display connects to a Macintosh SE/30 with a Micron Xceed video card, which also provides 256 grays on the SE/30's internal CRT thanks to the Grayscale Adapter. Also shown is a CPU-socketed Daystar PowerCache 50MHz 68030 CPU & FPU accelerator, and a second, lower-end Micron Xceed PDS graphics card — the Color 30HR.

• Dell 17" Display: tinyurl.com/5hfxh2k4
(Same as mine but without the "C" in the model number.)
• DB-15 (for Apple Monitors) to VGA adapter: amzn.to/34VhPZ9
• DeoxIT D5: amzn.to/3f92aeN
Expensive, but a truly amazing electrical contact cleaner. Trust me, your connectors will love you! It can fix some CRT display anomalies when used on the yoke board connector and CRT pins (with power off, of course), and it can clean out that greenish oxidation inside your old connectors, which can cause low voltage or intermittent lockups. It's really a must buy item. Thank goodness they sell it here in Japan too! 🙂
