Sansui AU-222 amp. I have fond memories of this amp #audio #repair

Ah… I didn’t, but can check grounds. Plus I have a number of photos of it.

De-capped, measured and now to go buy some new ones #apple2e

Oooohh…. That does not look good… even though the power supply does work. #apple2e

No point wasting good alcohol (Isopropanol) after cleaning keyboard switches… so glad a bought a chemistry set years ago 😁

Good to know😀😀🙏

Thanks, I have the ROMS sorted. The last issue is the keyboards often (too often) repeats keys. I have replace one of the Caps suggested (C71) but no change - Its most likely the keyboard decoder. I have ordered a new one off Ebay - hope its not a fake.

It's been fun fixing this Apple 2e. Program ROM's were dead. Fortunately I was able to download and burn new ROMs.

Love this! #retrocomputing #coding

Initial print done - Fits together beautifully. Needs a bit of touch-up, a brass thread, a switch and a spray paint.

A mod I've just finished to transform a Lightsaber into Kylo Ren's Lightsaber. Nor to do the final 3D print and assemble. More details to follow #maker

Those are needed for the retro computer and homebrew world. 😀😀

It's really bad form to have this on by default - It should be OPT-IN by default!!!!

That’s a wrap for the Commodore 1541 floppy drive repair and referb. Recapped, lubed up, broken drive door fixed and general clean…. And it even works!!

Production today starts with a dip in conformal coat to insulate the exposed wires and pads. #glowies #alpenglowies #ledjewelry

Nothing to see here dear….. 👀👀

His YouTube channel is great. I’ve leaned a lot from it.

Good to know. Thank you

Not sure yet. I open it up soon and test it. But can be dirt, bad pots, bad caps or solder joints… it’s (hopefully) not going to be too difficult to fix.
There is a really good service manual for it.

Ha… I didn’t know that Von Neumanns drive to design and build his computer was driven by his fascination about weather forecasting. The idea to be able to predict and control the weather. This was linked to Lorenz’s work on weather systems. Edward Lorenz created Chaos Theory.

The most frustrating and (now) useless key in history. It was useful decades ago, but no longer

I bought new memory for my sons laptop… this must be the new transparent version …. Package does not look like it was opened, but someone evidently has some new memory!!!

Getting a bit of retro fun in today. Got my retro collection out of storage (too expensive now) and doing some sorting… ok playing. After a quick head clean, glad to say the disk drive works. #retro

It’s a hard life but someone has to do it 😁😎
