Acorn RISC OS requires a mouse and it is very limited in use without it. This post describes in detail how to create a PS/2 Arduino adapter that connects to the 9-pin Mini DIN mouse port.

I was very fortunate to get this vintage computer from my friend Eric. This Acorn Archimedes A3010 was producted in 1992 by Acorn Computers and was based upon an ARM250 RISC microprocessor. Right away I proceeded to connect the computer to see if it still was in a working condition.

Playing games on emulators is usually bound to using arrow keys on the computer keyboard or an analog PC joypad. This ruins all the fun. The right way to do this is of course using a real arcade joystick.

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 purpuse it needed to be taken apart. It is a bit tricky as some of the parts are glued with advesive 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 hydroperoxide, 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 hudge database can be found on Atari Mania website. It is possible to mount these images with an Atari XL /XE emulator like Atari800Win. AtariAge website has an extended description on how to do it. However in this blog I am going to describe how to create floppy disks from these downloaded images so they can run on a real Atari XL / XE computer with a floppy disk drive.

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 buinding a custom CPLD version of it, the BASIC ROM chip (901226-01) was also broken. At the moment it is only possible to buy one that is salveged and the ones that I found were around 8 euros. A cheap alternative is to burn your own EPROM version of it.
