SHORTED! But Where? - SMD Ceramic Capacitor Roulette - Part 2

So in the last video I tried to fix a dead short circuit between 5V and GND by removing all of the electrolytic capacitors. Unfortunately that didn't work and the short remained.

In this video we're going to check the SMD ceramic capacitors to see if one of them is at fault. Don't worry, I've a fast and easy way to find the culprit, and spoiler.... this time we do! If you are planning on recapping an A1200 be careful with C407. It has a different orientation between Rev 1 and Rev 2 boards!

Get rid of that old spinning SCSI hard disk drive. In this video we're going to look at solid state alternatives for SCSI drives that we could install in our newly working A590.

I'll focus on the Blue SCSI V2, and once installed we'll re-install the operation system, OS3.2 and all of it's updates.


RARE A590 Repair - Epson Inside!? - Part 2

Did you know Epson used to make hard disk drives?! In the last video we took a look at the A590 and got the RAM working.

In this video we'll test out the hard drive side, and if its not working we'll attempt to fix it.


RARE Amiga A590 Repair and Fix - Part 1

I purchased a rather rare and early model A590 Amiga Hard Drive from Ebay. It has a really low serial number.
