# Vintage computer repair: Where nostalgia meets technical challenge The struggles of keeping retro tech alive and how it compares to modern devices - **Source:** [www.theregister.com - Articles](https://brifing.si/source/2c34ea50-d341-4a10-925d-12c012a9ad10) - **Published:** 2026-08-05 - **Original article:** - **On Brifing:** https://brifing.si/s/acccf0f0-682a-41e7-9ae7-121f89e84fce ## Origins of a nostalgic passion Earie Salmon's retro computer repair journey began with childhood envy of his brother's ZX81 and Commodore VIC 20 in the 1980s. Now owning 35-40 systems in 'various states of disrepair', Salmon describes this collector's drive as 'the desire to own what I couldn't have'. His professional IT background enables him to apply technical skills to revive vintage hardware that many consider obsolete. ## The disappearing parts problem The greatest challenge for retro repairers is sourcing custom ICs no longer in production. Salmon states 'finding ULAs and other custom chips made exclusively for discontinued computers is nearly impossible'. Some components only exist in 'dead' systems. While modern replicas exist for popular models, rare computers often lack such alternatives, forcing repairers to cannibalize existing units. ## The counterfeit chip trap Salmon's biggest frustration comes from fake electronic components. 'You might order 74LS logic chips only to receive completely different chip families,' he warns. Most IC testers can't detect these counterfeits. These unusable components often bear sanded-off and re-etched labels, wasting time and money. Salmon learned this lesson 'the hard way' through failed repair attempts. ## The critical skill of schematic reading Understanding circuit schematics proves vital for vintage computer repairs. However, Japanese computers (like NEC/MSX) often have documentation available only in untranslated Japanese. Salmon emphasizes how schematic knowledge proved crucial when fixing a BBC Model B previously 'repaired' with incorrect bodges and blown components by an overconfident amateur. ## Soldering wisdom Salmon advises newcomers to avoid 'hot spoon soldering' level mistakes by starting with practice on Vero boards before touching valuable vintage components. He stresses that skills should match ambitions, as poor repairs can permanently damage irreplaceable hardware. Proper desoldering techniques prove equally important when replacing faulty vintage chips. ## The unrepairable modern era Salmon argues post-mid-2000s devices adopted 'look how small we made it' designs that coincidentally made them nearly unrepairable. Where 90s computers used modular components, modern devices often require whole-unit replacements. He claims manufacturers now calculate component lifespans to last just 'warranty period plus one day', driving planned obsolescence and e-waste. ## Right to repair advocate Salmon strongly supports the right-to-repair movement, considering 70s-90s as the 'golden age' of repairable tech. He believes modern devices are deliberately designed to prevent repairs, forcing consumers into frequent upgrades. This practice not only burdens users financially but also contributes significantly to global electronic waste problems. ## Critical safety warnings Salmon's most crucial advice for new repairers concerns electrical safety: 'Never work with mains voltage until you're absolutely confident, and always keep it covered.' He warns that accidental contact with high-voltage components during focused work happens to most electronics hobbyists. Such mistakes could prove fatal, making safety the foremost priority in any repair project. ## Sources covering this story - https://www.theregister.com/offbeat/2026/08/05/keeping-yesterdays-computers-ticking-takes-more-than-nostalgia/5282729 — --- _Summary written by Brifing from the original reporting.
