Gotek floppy disk emulator can not be used on an Amiga computer without modding it. Luckily it is not hard to change the firmware on the device to be able to boot ADF images from an USB drive.

After I have bought this Amiga 500 computer, the cover was in very bad shape. The previous owner tried to retr0bright it, but it didn't work out as planned and there were a lot of spots.

Two old computer mice turned yellow over the years and needed some brighting up. To achieve this we are going to use the retr0bright method.

This vintage Canon parallel scanner needed some restoration and for that purpose it needed to be taken apart. It is a bit tricky as some of the parts are glued with adhesive tape and need to be detached very carefully. This small tutorial shows a step by step disassembly instructions of the scanner.

If you have old plastic cases that have turned yellow, you can restore them to it's original state just by using hydro-peroxide, some oxy powder, UV light bulbs and patience. In our test we will be restoring an old Canon flatbed scanner cover that had turned yellow

In this project we are going to create a simple BASIC program, then save it to the tape (which in our case will be a wave form on a PC) and in the end convert it to a TZX image file that can be run on a ZX Spectrum emulator like Fuse.

There is plenty of free software available for the 8-bit Atari XL / XE computers online in the form of ATR files. These are image files created from the physical disks. A huge database can be found on Atari Mania website.

A while back I have bought a cheap second hand Commodore 64. Unfortunately it was broken, next to the PLA chip which I have fixed by binding a custom CPLD version of it, the BASIC ROM chip (901226-01) was also broken.

The most important chip in commodore 64 computer is the PLA chip. When this chip is broken, nothing will work and most certainly you will get a black screen after you try to turn it on.

FPGA's and CPLD's are certainly very cool devices. It is possible to create you own logical circuits and emulate real hardware chips on the lowest level. For this test project we will use Alera CPLD which is also known as MAX3000A and it's full code is ALTERA  EPM3064ATC44-10.
