Rybags Posted February 1, 2008 Share Posted February 1, 2008 The metal shield is missing from the cartridge bay door, HAL: The circuit board seems to be bubbling out a bit - fairly natural for really old gear. Quote Link to comment Share on other sites More sharing options...
Tempest Posted February 1, 2008 Share Posted February 1, 2008 The metal shield is missing from the cartridge bay door, HAL: Yep my personal Atari 400 (from 1980) did the same thing. I need to stick it back on sometime. Tempest Quote Link to comment Share on other sites More sharing options...

+bcombee Posted February 1, 2008 Share Posted February 1, 2008 (edited) According to the Best Electronics catalog, the Atari 400 uses a 9V AC power supply (18.5W for the 400-only supply, 50W for the universal one), where the 5200 uses a dual 9.3V/11.3V DC power supply. In other words, don't plug the 5200 supply into this computer! Edited February 1, 2008 by bcombee Quote Link to comment Share on other sites More sharing options...

mimo Posted February 1, 2008 Share Posted February 1, 2008 B+C have those keyboards if you want a complete replacement, about $25 IIRC Quote Link to comment Share on other sites More sharing options...

andylama Posted February 4, 2008 Share Posted February 4, 2008 As for the "moisture looking" or "bubbling out"--don't worry, that appearance is normal. In most cases, it is an unusually thick layer of solder, flow-coated over the circuit traces during manufacture. Then they apply a protective green coating over that to prevent oxidation. All in all, it's a good thing. Quote Link to comment Share on other sites More sharing options...

+Stephen Posted February 10, 2008 Share Posted February 10, 2008 That shield is not necessary. The only way to get another one would be from a donor machine, or you could always cut your own fom a thin sheet of aluminum.

Gunstar Posted February 13, 2008 Share Posted February 13, 2008 For that missing spacebar piece, you could probably make your own using that one as a template, just find a piece of plastic of about the same thickness and use and exacto/razor knife to trim it to the same shape, then use a drill to cut the hole (get a proper bit that fits the width, then make two holes spaced for the oval shape then use the razor knife to cut the rest out.
