Vintage Home Computers & Boards

A single C64 SID chip sells for $70–170; the entire motherboard it sits on scraps for $3. If you can read a four-digit MOS or Commodore part number, look it up before the board goes near a shear.

How to spot it

C64 boards are brown/tan PCBs marked ASSY 250407/250425/250466/326298 with socketed 40-pin DIPs — 6510, 6581/8580 SID, 6567/6569 VIC-II with a heatsink clip, 906114-01 PLA, 6526 CIA — and a cartridge edge at the rear. Amiga uses 8372A Agnus in 84-pin PLCC plus Denise 8362 and Paula 8364. Apple II is a large green board with eight slots and white ceramic DIPs with gold lids, silkscreened APPLE COMPUTER INC 1978/1980. Look for rainbow Apple, Commodore chicken-head and Atari fuji logos.

Metal content

MetalQuantityNotes
Gold0.05–0.20 g per C64 board; 0.1–0.4 g per Apple II boardCartridge and user-port fingers plus ceramic DIPs. Derived, no assays
Goldgold-lid ceramic DIPs at $150–400/lbThe only genuinely rich fraction — but a C64 board yields zero of them, it is all plastic DIP
Copper~40 g/lbTraces plus ~150 g of copper and iron in a C64 brick PSU

At 4 Aug 2026 spot prices that works out to $16.1 per pound of contained metal — Gold 0.12 g = $15.7, Copper 40 g = $0.43. A refiner paying $3.2 returns about 20% of that, which is normal: refining costs money and the buyer takes a margin.

Safe removal

Working temperature: Hot air 300–330 °C, preheat 120–150 °C

Don't desolder — desocket. The value chips on C64, Apple II and Atari 8-bit boards are almost all socketed: use a DIP extractor or two small flat screwdrivers levering alternately from both ends. For soldered PLCCs use hot air at 300–330 °C with the board preheated to 120–150 °C, because 1980s single-sided phenolic lifts pads at the slightest excess. Store chips in anti-static tubes — these are NMOS parts and a static zap is a $100 mistake.

Hazards

💥 CRT implosion, leaded glass, phosphor

NEVER pick up or carry a CRT by the neck.

⚡ Stored high voltage

NEVER short a large capacitor with a screwdriver. It welds the tip, blasts molten metal at your face, and can rupture the can.

☠ Lead — dust more than fume

NEVER dry sweep or use compressed air on a scrapping bench. HEPA-vac or wet-wipe only.

⚗ Home acid refining

The practical answer for nearly everyone: sort, concentrate, and sell to a licensed refiner. A good refiner recovers 85–98%, assays rather than guesses, pays on the assay, and takes the waste liability. Your edge as a scrapper is identification and sorting — not chemistry.

🛢 PCBs (polychlorinated biphenyls)

NEVER puncture, drain, burn or bin a suspect unit. Burning PCBs produces dioxins and furans.

🧱 Asbestos

NEVER cut, drill, sand, tear or blow out suspect material with compressed air.

☣ Beryllium oxide (BeO)

NEVER grind, sand, file, saw, drill, abrasive-cut, sandblast, hammer, crush, shred, torch, melt or incinerate anything that might contain BeO. Sell or dispose of suspect parts intact. Broken beryllium parts are worth nothing; your lungs are worth everything.

Before you scrap it

The most value-destructive scrapping decision in consumer e-waste. A working C64 system is $150–320 against $0.50–2 of scrap — 100–600×. Even parted out, one C64 board yields SID + VIC-II + PLA + 2 CIA + CPU = $175–410 from a board that scraps for $3. Check for a barrel battery, replace the RIFA caps, power it on with a known-good PSU and photograph the boot screen — that five-minute sequence is worth more than every gram of gold in the machine.

The common trap

Old boards are gold-rich — partly true for 1977–1982 ceramic-package machines, false for anything after ~1984 when the industry moved to plastic DIP. A C64 board contains no ceramic gold-lid parts at all and scraps for $3. Second trap: assuming not working means scrap — most dead 8-bit machines fail on the PSU, one electrolytic or a socketed logic chip, and a dead C64 still sells for $60–140 for its SID, VIC-II and PLA. Third: a C64's cartridge fingers are worth about forty cents.

Questions

How much gold is in vintage home computers & boards?

Gold: 0.05–0.20 g per C64 board; 0.1–0.4 g per Apple II board. Gold: gold-lid ceramic DIPs at $150–400/lb. Copper: ~40 g/lb. At current spot that is about $16.1 of contained metal per pound.

Is vintage home computers & boards worth more working than as scrap?
