The 20 greatest home computers – ranked!

This will probably bring a tear to the eye

This Mac 512k (Sept 1984 - April 1986) almost brought a tear to my eye, and for good reason.
I was given one four years ago, and unfortunately like many vintage components, someone had left the back-up battery installed. And like many, the battery had expired and leaked it’s corrosive acid within the battery compartment, over chassis components, and ‘horror!’ - over the motherboard.
Preferring vintage Mac laptops to work on, I’d never refurbished a desktop 512k let alone one in this state, but thought I’d accept the challenge. Needless to say it wasn’t easy.
Here are a few before/after photos of various components.









Due to complications with the motherboard, this project is currently on-hold and in storage pending completion of a few other of my Mac refurb projects.




A lesser-known feature of this model is that all the team associated with it - including Steve Jobs, signed their names, which were then transposed across to the casing during fabrication. When the cover is removed all the signatures are visible inside.

What did you use, pepsi/coke or something similar like we used to make pennies nice and shiny?

No. I asked on a specialist forum and was advised to contact a car-repair bodyshop and get the worst parts sand blasted. But eventually just bit the bullet and got stuck in using emery cloth and a lot of elbow-grease. Then a light spray from a silver aerosol can to finish off.

For info if there are any AppleMac fans here, a short while back after searching for years, I found and purchased a TAM (aka Twentieth Anniversary Macintosh), produced June1997-March1998, a very rare beast, and hoped that the internal battery was either removed or in good condition. Fortunately it was ok, and the computer fully functional - a big relief! Marvellous machine for it's day, with an astronomical price when released.

I didn't/don't own this, but it was the first computer-type thing I ever worked on, at a friend's house. The type was green and the most frequent and unhelpful message was "fatal error".

Nice computers in this

My first computer was the Commodore 16 with the separate tape deck. I probably spent more money on games and joysticks than the thing cost but it kept me entertained right up until the NES came out. You don't get games like Punchy anymore.
