  1. Thank You Mr Piotr for Your doing an outstanding job on my mashine!
    For all those in doubt – Yes, the photos on this page really do justice to the actual state of my computer. It came out beautiful.
    Not only did Mr Piotr tackle the job at hand, which was outside His comfort zone – considering His forte is mostly in the Amiga line of computers.
    But He did so with the utmost care and consideration, as is due for a classic piece of mashinery, such as the 8-bit Atari. 😉
