Atari Engineering 7800 Composite Monitor Rev. 2 Upgrade!
General Information
When Best Electronics helped cleared out all of the Sunnyvale Atari Warehouses over a 10+ year period, one of the additional buildings we bid on and got the rights to remove any Atari Hardware from was the Atari Corp. Main building 1196 Borregas Ave. In this Atari Corp. building was Atari Purchasing, Engineering, Engineering Prototype lab, Sales, Accounting, Marketing, Legal and other Atari departments.
In the Atari Engineering section we came across a single Modified US Atari 7800 console. It got put into a box and stored onto one of the thousands and thousands of Pallets of Atari goods we put into our San Jose Warehouse over the years. We recently finally broke down one of those Pallets of Atari items from the Atari Corp building and again found the Engineering 7800 console. To us this 7800 looked like an Atari Engineer’s modified 7800 with a Composite Video mod installed console. This Modified stock Atari 7800 motherboard had two Engineering mods installed. The 7800 Composite Video Mod and the Euro 7800 Operating Chip mode. See the past this Composite Video Upgrade for more information on this second 7800 OS Chip mod.

Best Electronics has Engineered two upgrades to the Atari Engineers original Composite Video design by enhancing the Video display with a sharper Composite Video Display with improved color display and color saturation. The Best second 7800 CV upgrade to the original design, is for the 7800 Game Cartridges that have a Pokey sound chip within the game cartridge. This Pokey 7800 game cartridge based sound output was missing from the original Atari Engineers CV design.
This 7800 Composite Video mod is relative easy mod to do. It requires, removing (unsoldering the internal 7800 RF Modulator), removing some 7800 motherboard components, adding some new components, cutting and lifting up some soldered in 7800 motherboard components. But there are no permanent 7800 Motherboard trace cuts or modifications to the 7800 motherboard which can not be reversed should this composite video Mod not work for you. Compared to other more expensive 7800 Composite video upgrades, the Atari Engineering version does not require any cutting, drilling, or modifying of the Atari 7800 top or bottom plastic cases. Because you will remove the Atari 7800 internal RF Modulator in this 7800 upgrade, you will no longer be able to connect up your Atari 7800 to your TV thru the normal RF cable to the rear Coax TV input / TV Switch box.


The quick way you can tell you if you have the US 7800 Motherboard, check to the left of the Atari 7800 right angle Power jack on the Atari 7800 Motherboard. If you find a MJE 210 (see Red Arrow above) Transistor next to the 7800 Power Jack, you have a US 7800 motherboard.
Items required for this 7800 Composite Video Modifcation.

Needle Nose Pliers
Small pair of Diagonal cutters

This upgrade is so simple no schematics / prints are supplied. You should be able to solder and unsolder, read Resistor color codes and read the silk screen component locations on the Atari 7800 Motherboard
About 1 to 2 hours installation time.
A 12 page written set of Installation instructions with 10 color pictures
All Electronic Components required for this 7800 Composite Video Mod.
Set of 6ft Composite Video and Audio cables with Gold Plated connects modified for installation onto the 7800 motherboard

Best Atari 7800 Tech tip: If you are considering doing this 7800 Composite Video mod or Euro 7800 OS Upgrade, you should also consider ordering at least two new replacement 7800 On/Off and Game Start/Reset switches ($1.50 each). On all Atari 7800 consoles these two soldered in 7800 switches have a Very high failure rate and should automatically be replaced if you go inside your 7800 console.
Atari Engineering 7800 Euro Operating System Upgrade Mod for US 7800 Consoles!
General Information
Atari Engineering released two versions of the Atari 7800 Operating System chips. The US version has the known 7800 boot up screen with the Atari Logo / color bars and delay before the inserted Atari 7800 game cartridge screen appears. The Euro 7800 OS chip / 7800 Euro Consoles have a build in Atari 7800 Asteroids game (turn on your 7800 with no game cartridge inserted and 7800 Asteroids would be the default game) and will instantly start any 7800 game (no more Atari 7800 Logo delay screen) when a 7800 game cartridge was installed. Both versions of the Atari 7800 OS chips both instantly start up all 2600 Game Cartridges.
When Best Electronics cleared out Atari Engineering department we found several Atari Engineering samples of US 7800 consoles modified with a Universal PAL / US upgrade version 7800 OS chip. This Atari Engineering Enhanced / Hybrid / Universal Atari 7800 OS Upgrade chip can be installed in any US / NTSC 7800 console and will give you the same above upgraded features as Atari Euro version 7800 consoles produced. To Install / Upgrade in a US 7800 console, requires some soldering, additional I.C. chip, trace cutting and an extra wire jumper added to a US 7800 Motherboard.
