Twelve things a single Saturn taught us about retro refurb.
One PAL Sega Saturn from a Newcastle estate clear-out. Every drama known to the bench — a weeping cap bank, a missing internal battery, a stuck disc-tray, a CR-2032 holder pulled clean off the board. A short education, in twelve numbered items.
Always smell the box before you open the system
If the carton smells of damp, of smoke or — in our specific case — of cat, the board inside has had a longer story than the photos suggest. Smell is the most reliable single signal you get during intake.
A Saturn's PSU cap bank is the most dramatic component on the bench
When one cap goes, the others tend to follow inside the year. If you find one swollen 470 µF, plan to replace all six — and the two 100 µF parallels too. Panasonic FR series, never the cheap Chinese clones.
The CR-2032 holder is unreasonably easy to snap off
The retention pegs are spot-welded, not soldered. Pry too hard at a fifteen-year-old corroded battery and the holder lifts clean off the board, sometimes with a copper trace attached. Keep replacement holders in stock; this happens more often than you'd think.
The disc-tray gear teeth fail before the laser does
If a Saturn ejects unevenly, the laser is fine; it's the worm gear inside the tray mechanism. New gears are available — search "Sega Saturn tray gear" on the usual sites. Three quid, two minutes' fitment.
An ultrasonic bath at 60 °C for nine minutes is the magic number
Hotter or longer and you risk lifting solder joints; cooler or shorter and you don't get the flux residue or nicotine yellowing off. Isopropanol over distilled water, 9:1 ratio. We learned this the hard way on the third Saturn.
Photograph the board before you start, not after
Three angles, top-down, two LED ring-light positions. If a customer asks "what did this look like before" later — and a few do — you have it. Also useful when you've forgotten which ribbon went into which header.
The lithium cell is a 1996 part — never trust the original
Even if it reads 3.0 V on the multimeter, replace it. The CR-2032 holder doesn't take corrosion gracefully, and a "fine" cell can puddle inside six months.
Keep a parts board in the cupboard, always
One Saturn we wrote off five years ago lives in the spare-parts cupboard. It's donated a CR-2032 holder, a power LED, a regional jumper resistor, and three trace-jumper wires across the last six refurb passes. The cupboard is the most cost-effective thing in the lockup.
The PAL Saturn's regional jumper is a 0 Ω resistor — easy to mis-flag
If a board's been modded for region-free, the jumper position will tell you. If it's been done with a hard-wired switch, look for the second hole. The third method — a 256 kbit cart — leaves no trace and we always disclose if a system has been previously modded.
Burn-in for 23 hours minimum, with Wipeout on loop
Wipeout 2097 PAL pushes every part of the Saturn hardware harder than any "test" cart you could buy. If a system passes a 23-hour Wipeout burn-in without an audio glitch or a CD-read error, it's going to be fine on a customer's shelf.
Always photograph the boot screen as proof-of-pass
Saturn boot, twin disc spin, audio playing. Time-stamped, posted into the lockup's internal Discord. If a customer asks for warranty proof a year later, we have it.
Sell the system back to the original seller's neighbourhood if you can
This Newcastle Saturn sold to a buyer in Gateshead — five miles from where it came in. The original seller asked for a photo of it on the shelf; we sent two. It's the part of the job that justifies the early starts.
