欢迎来到主机拆解周的第三天，目前我们已经拆了 Magnavox Odyssey 100和RCA Studio II，雅达利 2600就是我们下个目标。我们和partnered with PC World 合作的这个拆解让大家一窥当年游戏主机的主角。
Your IC ID on this teardown is incorrect.
The Rockwell chip in the middle CO10745 is the 6507 CPU
The Motorola CO10444 is the TIA and the Synertek is the 6532 RIOT IC

Agreed, and I don't get how you guys came to the conclusion of "a great appreciation for [...] hand drawn circuits".
I see nothing but straight lines, which very well could be neatly hand drawn, but just as easily could be CAD'ed.
But otherwise I love your teardowns of classic hardware. Keep them coming!
Perhaps they meant to suggest that the traces were laid out manually using a CAD program, as opposed to auto-routed?
Perhaps by "hand drawn" they meant "hand taped," the more usual method for circuit layout. While I have done small boards with a photo-resist pen on the copper or a marker on a mylar mask, it was more usual and easier to use a strong black tape on the copper or the mask. It came in varying widths, and you could also buy stick-on or transfer pads for through-holes and sets of pads for ICs. When taping out stuff it was definitely easier to do straight lines than curves!
