Blue Azure Posted September 16, 2013 Share Posted September 16, 2013 I looked but never found these Atari 7800 docs on the net. This is a copy of the telex from 1984, but still readable. With the XM release pending, it's a good time to start dusting off the good ole 7800 and make it run. As the XM games aren't exactly compatible with the emulators, you'll need a working 7800, and soon. The zip pkg includes the 7800 Theory of Operations, albeit somewhat simplified and refers to a schematic not included, but aa.com has the one page schematic complete; the 7800 Block Diagram, also simplified; and the 7800 Diagnostic Flowchart, a.k.a. Troubleshooting Guide. This flowchart was obviously intended for newly-built 7800s, but you can still use it. One comment: NEVER drop kick your 7800 and throw it in the trash - there's some good parts in there!!! Give it to me!!! Gimme gimme gimme... 7800 Atari Theory of Ops.zip Enjoy, ///BLUEman/// Quote Link to comment Share on other sites More sharing options...
+Mitch Posted September 17, 2013 Share Posted September 17, 2013 Cool! It looks like part of the 7800 service manual. Too bad some of it's missing. Where did you happen to find it? Mitch Quote Link to comment Share on other sites More sharing options...

Curt Vendel Posted September 17, 2013 Share Posted September 17, 2013 Blue - thought I sent you those doc's, I'll pull out the folder later tonight and scan them up for you and post so that there is a cleaner and complete set available.

Blue Azure Posted September 17, 2013 Author Share Posted September 17, 2013 That's right it came from dumpster dive 7800-99. I thought I had a photo of "the plunge" but can't find it. I don't know, Mitch, was there a 7800 Repair Manual from ca.1986? Shouldn't we post it? I don't have it. My 7800 works and it's XM-ready!!! But is my XM ready for me? ///blueman/// Quote Link to comment Share on other sites More sharing options...
+Mitch Posted September 18, 2013 Share Posted September 18, 2013 Curt, if you can post the complete file that would be awesome. Mitch Quote Link to comment Share on other sites More sharing options...
+Mitch Posted September 20, 2013 Share Posted September 20, 2013 Here's a part's list/BOM for the NTSC 7800 that I made a few years ago but never got around to posting. I was working on a silkscreen as well but never finished it. Maybe Curt's copy will have the official one.

Blue Azure Posted September 21, 2013 Author Share Posted September 21, 2013 BOMs away!!! Thanks 2 Mitch. I agree, this is great. Who would have thunk it 30 years ago we'd be doing all this on the 7800 now? I often wonder if GCC personnel are watching our "progress" on a machine design that must have died many, many years ago. I think we're going stronger here than the 26 and/or 52, although there are still brilliant folks over there as well. I think we have the edge with the publicized source lists and many disassemblies. Leading to the equation... 7800 > 5200 + 2600 Not to be nitpicky on Mitch, but the CR2 listed on the parts list is the Power LED. It would be interesting to see if we can dig up a costed BOM so we know how much these parts cost in 1984 +/-, especially the memory devices. Sometimes they were pricey and hard to come by. ///blueman/// Quote Link to comment Share on other sites More sharing options...
+Mitch Posted September 22, 2013 Share Posted September 22, 2013 Not to be nitpicky on Mitch, but the CR2 listed on the parts list is the Power LED. Good catch there! I just posted an updated version. If anyone finds any more errors please let me know. Mitch Quote Link to comment Share on other sites More sharing options...
