This Video Composite MOD needs some work unlike other similar consoles, you need to remove a resistor and insert a trimmer, otherwise the Video Composite output signal is really bad.

Works that need to be done:

• Remove the RF Modulator (remove it completely)
• Remove the 4.7k Resitor (see photo)
• Solder a 22k Trimmer between the resistor hole (hole side to pin 8 of the TEA 1002/PE1X) and the ground, the third pin of the trimmer is the Video Composite output. (see photo)
• Solder a wire for the Audio output. (see photo)
• Use the same hole of the RF cable for the new video and audio cable.

Before closing everything i recommend to adjust the trimmer for the best Video output.

Commodore Amiga A570 Restoration.

I have received two retro things in very bad conditions.

• 1 x Floppy Drive CD-1411
• 1 x Commodore Amiga CDROM A570

… but for now we are talking about the Commodore A570.

The Commodore A570 have serious problems that i list below:

• Outside case is very dirty, yellowed and broken in several parts.
• The Caddy Guide Tracks has been destroyed.
• Damaged screws thread.
• The metal plate under the CDROM is bent on one side.
• Many rusty parts.
• Main PCB with traces of water/limestone and rust.

Works that have been made:

• Fixed the CDROM CADDY holder, it was not easy because all the metal guides are bent, now it works.
• Main PCB cleaning on both sides with the Kontakt PCC and toothbrush.
• Cleaned and grease the two rails of the laser head.
• Cleaned the head lens of the CDROM.
• Fixed the bent metal plate under the CDROM.
• Cleaning outer casing.
• Fixed with the glue the two pins for closing the case with the screws.

Work still to be done:

• The bottom part of the A570 CDROM is very rusty, i need to sand down gently and at least give a hand of anti rust.

Aesthetically is very bad but at least works.
