    Don't judge the 65816 speed by the Apple IIGS, the GS was intentionally run at a slower clock speed so that it wouldn't make the Mac look bad.

    Finally getting around to this, here is the 800 I got on ebay: Which was purchased around Aug of 1980 (for AtariLab maybe?) according to this: Then inherited or folded into "SIP" in 83 It appears to have been upgraded to GTIA and max memory, maybe in 83 (one chip on CPU card looks to be a different vintage and came with 48K memory)

    I vaguely remember that a court ruled against Nintendo late in the GB life that it isn't a trademark violation if it is required for interoperability. In other words the GB DRM didn't fly legally, you may freely include Nintendo's logo for the purpose of booting the console. Edit: It might have been Sega, they did something similar with one of their consoles. Still applies to the GB though

    We have all been there. I remember printing out a 1000+ line Turbo Pascal program in high school because the compiler was acting like I was missing an End somewhere. Drew lines matching Begins and Ends, and still couldn't find where I messed up. Had someone else look at it and right away spotted that either there was a semicolon was missing or where there wasn't be one. God I felt stupid

    Awesome! I heard it said the self-test was primarily a marketing tool anyways.

    If your computer is socketed you can use this to remove the need for soldering: https://www.tindie.com/products/devzine_pl/sally-adapter-for-atari-xlxe-and-ultimate-1mb-mod/ It is out of stock, but you can try contacting the seller and see if he can whip one up. I use one in my 800xl and like the fact it is completely reversible.

    The Apple IIs had less shielding because they were designed to connect to monitors not TVs (pay no mind to Woz's friend selling a cheap and easy RF addon board down the street) and thus used much more relaxed rules.

    Anyone got a spare PCB?

    Maybe you be better off with the 1090 80 column emulation instead, it far easier to get working. Getting VBXE working requires multiple steps and at least with sdx making a config.sys

    In answer to #2 The 400/800 RF Shield was designed to conform to a very strict set of FCC guidelines because it used normal TVs as a output. Later the FCC relaxed these guidelines to be more in line with those computers with monitors dealt with, so a smallish sized hole shouldn't have a major effect on anything else because overshoots current (and any sane) regulations by a wide margin.

    Everything is working thx everyone. We still need to adjust the POTs to the correct image, I am getting everything setup for it right now. I am happy to have a working Atari, a 400 was my first computer.

    Still working but we made to the system test screen

    Just trying to get the system up, we are getting either a black or red screen (we are colorblind and the lcd is old). I have a voltmeter with discontinuity checking and that is about it. We were pulling up chips and reseating them to see if that fixed the system.

    Hi, I recently bought a 800xl which I am attempting to get working. We accidentally powered the system on with the GTIA off by one peg (to the right) . Did we permently damage it?
