 <h2>Role in the Fleet</h2>
 <p>This machine serves as a nostalgia and comparison reference. When problems occur on one of the modified Megas, I can test against this unchanged original state to distinguish bus, flash, or configuration errors from genuine hardware faults. It can also be used as a test platform for uncritical experiments, but stays as close to original as possible for nostalgic reasons.</p>

 <li><strong>Blitter patch</strong>, removed an existing patch and carefully bridged the severed trace with wire, verifying it with a continuity test. The installed blitter (marked S9012 / MM9092V, a National variant from week 12/1990) belongs to an unproblematic batch where the classic Mega ST blitter patch is generally no longer needed.</li>

 <p>Bought via eBay as a bargain, this Mega ST 4 is today my LowRes demo and gaming machine. It's the most heavily expanded of the fleet, but tuned for fast disk-image swapping rather than productivity.</p>

 <h2>History and Repair</h2>
 <p>I had originally cut out the TOS ROMs to experiment with external solutions, and afterwards it was unclear whether the board had been damaged in the process. Moving the <a href="/retro/storm-cloudy/">Cloudy/Storm ST combo</a> to this machine via the MegaBus connector brought it back to stable operation. The actual problem turned out to be a poorly and incompletely soldered CPU socket.</p>

 <h2>History</h2>
 <p>Everything in this machine was moved over to the <a href="/retro/mega-st-high/">Mega ST 4 "High"</a> that I was given, including its original power supply. It's not really a parts donor though, it's simply the spare machine now that the new Mega 4 carries the main setup. Back then it had an intermittent fault: after being on for a long time it would eventually show a white screen on boot. I first suspected the 4 MB expansion and removed it, but the fault persisted. Only after reverting it to the old TOS and a fully original state did it run stably again.</p>
