A few things to repair for a friend.

• Enterprise 64
• Archimedes 310

Defect: unknown.

I have repaired an Atari 800XL for a friend. The failure was caused by a faulty cpu, the computer freezes after 10 minutes of operation, using an oscilloscope i have noticed that the clock pin of the cpu did not give me more signal but when i have used the synthetic ice spray on the cpu has resumed to work.

This type of cpu (Atari customized 6502 – C014806-12 Sally) is not easy to find but fortunately a friend of mine (Carlo) has found a spare part for me.

Jump here for the commercial RGB mod for the Mattel Intellivision

I have found this RGB mod for the Mattel Intellivision console fom a site, i have searched on the net if anyone has tried this mod, but nothing, so, i have tried to do it myself.

This mod is not easy to do, especially if one has no experience in electronics, however the result at the end is spectacular.
