Yet Another Restomod Of The Greatest Computer Ever

The best computer ever made is nearly thirty years old. The Macintosh SE/30 was the highest-spec original all-in-one Macs, and it had the power of a workstation. It had expansion slots, and you could hang a color monitor off the back. It ran Unix. As such, it’s become the prize of any vintage computer collector, and [Kris] recently completed a restomod on our beige king. It’s a restored Macintosh SE/30, because yes, we need to see more of these.

The restoration began with the case, which over the last thirty years had turned into an orange bromiated mess. This was …read more

Restoring An Apollo Guidance Computer

The Apollo Guidance Computer is a remarkably important piece of computing history. It’s the computer that guided the Apollo lander to land on the moon. We’ve seen a few replica builds over the years, but [CuriousMarc] got a closer look at one of the real things. In this video, [Marc] gets a look inside as his colleagues take apart one of the original AGCs and get a closer look at the insides of this piece of computer history. 

Thanks to collector [Jimmie Loocke], they got to take apart AGO#14, one of the original flight computers from a Lunar Excursion Module …read more

Ants, Dirt, Rain, And The Commodore 64 That Wouldn’t Quit

Some electronics gear is built for the roughest conditions. With rugged steel cases, weatherproof gaskets, and cables passing through sealed glands, these machines are built to take the worst that Mother Nature can throw at them, shrugging off dust, mud, rain, and ice. Consumer-grade computers from the start of the home PC era, however, are decidedly not such machines.

Built to a price point and liable to succumb to a spilled Mountain Dew, few machines from that era that received any kind of abuse lived to tell the tale. Not so this plucky Commodore 64C, which survived decades exposed to …read more

A Switching Power Supply, 1940s-Style

“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its original parts. But when said power supply is about the size of a smallish toddler and twice as heavy, building them like the old days isn’t everything it’s cracked up to be.

The power supply that [Ken Shirriff] dives into comes from an ongoing restoration of a vintage teletype we covered recently. In that post we noted the “mysterious blue glow” of the tubes in the power supply, which [Ken] decided …read more

Restoring A 100 Year Old Vice To Pristine Condtion

We love our vices. They hold pipes for us to saw away at, wood while we carve, and circuit boards so that we can solder on components. So we keep them in shape by cleaning and greasing them every now and then, [MakeEverything] went even further. He found a 100-year-old vice that was in very rough shape and which was going to be thrown out and did a beautiful restoration job on it.

It was actually worse than in rough shape. At some point, one of the jaws had been replaced by welding on a piece of rebar where the …read more

Refurbishing A DEC 340 Monitor

Back in the “good old days” movie theaters ran serials. Every week you’d pay some pocket change and see what happened to Buck Rogers, Superman, or Tex Granger that week. Each episode would, of course, end in a cliffhanger. [Keith Hayes] has started his own serial about restoring a DEC 340 monitor found in a scrap yard in Australia. The 340 — not a VT340 — looks like it could appear in one of those serials, with its huge cabinets and round radar-like display. [Keith] describes the restoration as “his big project of the year” and we are anxious to …read more

Restoring an Atari 800 XL that’s Beyond Restoring

Sometimes the best way to get a hacker to do something is to tell them that they shouldn’t, or even better can’t, do it. Nothing inspires the inquisitive mind quite like the idea that they are heading down the road less traveled, if for nothing else to say that they did it. A thrown gauntlet and caffeine is often all that stands between the possible and the impossible.

So when [Drygol] heard a friend comment he had an old Atari 800 XL that was such poor shape it couldn’t be repaired, he took on the challenge of restoring the …read more

Restoring A 1930s Oscilloscope – Without Supplying Power

We’ve all done it: after happening across a vintage piece of equipment and bounding to the test bench, eager to see if it works, it gets plugged in, the power switch flipped, but… nothing. [Mr Carlson] explains why this is such a bad idea, and accompanies it with more key knowledge for a successful restoration – this time revitalising a tiny oscilloscope from the 1930s.

Resisting the temptation to immediately power on old equipment is often essential to any hope of seeing it work again. [Mr Carlson] explains why you should ensure any degraded components are fixed or replaced before …read more

Refinishing A Vintage KitchenAid Mixer

If you know anyone who is serious about baking, there’s a good chance you’ve seen one of these classic KitchenAid mixers. Built to last, they are often handed down generation to generation (or at least, when a newer model comes out), which is how [Kaitlin Flannery] received hers. While it didn’t look too bad considering its long life and the fact it’s been through a motor replacement already, she decided to spruce it up a bit by stripping it down and repainting the whole machine.

These KitchenAid mixers are solidly built and look highly serviceable, it’s refreshing to see a …read more

Yellowing: the Plastic Equivalent of a Sunburn

Your fancy white electronic brick of consumer electronics started off white, but after some time it yellowed and became brittle. This shouldn’t have happened; plastic is supposed to last forever. It turns out that plastic enclosures are vulnerable to the same things as skin, and the effects are similar. Whey they are stared at by the sun, the damage is done even though it might not be visible to you for quite some time.

Photodegradation

Photodegradation is nature’s way of saying you should be playing more video games indoors instead of being outside. The process is complicated and full of …read more
