I don't know where are you from. You can use GTIA the same TV version for replace, i.e. if your 5200 is NTSC, then you can use GTIA from Atari 400, 800, XL or XE NTSC version only. In some versions of 5200 10 pin of GTIA is bend out of socket, you should make the same in new chip. And next about signs: GTIA NTSC is signed CO14805, PAL CO14889, SECAM CO20120.

Sure, this is the same chip, but different signs. Remember bend pin as in original chip, if needed.

Candle wrote me that will be VBXE 3.0 in future, but when exactly You should remember that VBXE was designed for Atari XL/XE series, so 5200 special needs, and then most of the core capabilities VBXE not be able to be used. Atari 5200 needs fresh blood, it must go forward. There are already good solutions (ie Ultimate SD cartridge), but the need for new and better games, using stereo sound, additional memory and graphics VBXE. XL/XE and 5200 systems are very similar, need to use the achievements of others for better play.

Rod, do not give up so easily. When 5200 stopped working after assembling, it is probably shortcut on the port expansion circuit (rear left). Check that this connector does not shortcut by RF cover. When, after removing the RF cover still does not work check if there is a warm any little chip 74xx, or RAM and replace it.

VBXE has the ability to use their own memory as a ramdisk 320kb (for the XL / XE). 5200 has too many limitations to be able to meaningfully use the ramdisk. But it is the Ultimate SD Cartridge.

Hi Rodrigo I think that you solve this problem yet. If not - you can check your power adapter using 12V/21W car bulb (i.e. stop or direction light), it should lightup. Then you can measure output voltage under load and proper polarity. This voltage should be min. 9V (DC). Next check cleaning of cartridge socket and cart edge connector. Remember that 5200 startup only when cartridge is proper inserted, but red LED should lights without cart.

For some time there VBXE, which allows for an RGB image. This module is mounted in one of my 5200th. Picture a wonderful and clean, without distortion and streaking Look at http://atariarea.krap.pl/forum/viewtopic.php?id=7476 Prepared the little installation instructions: http://www.dereatari.republika.pl/VBXE5200.doc

Many years ago I accidentally plugged the power supply from 1050 to the 5200th. I did not notice the error, and dug the whole 5200 board, replaced 4013 and resistors, until I noticed that the power supply does not proper. 5200 lived happily

Are you sure that your power adapter is AC?
