First Atari PCB: Lunar Lander

http://www.dsbelec.iinet.net.au/lunar_lander_PCB.htm

Anyone interested in a reference chart for Lunar Lander PCBs?

EDIT: Excel Version here

I put this together to make it easier to repair and identify the ICs while recently repairing the PCB.

I had some ram issues

Is there anything else available for other Atari PCB's ?

Anyone got other info to add maybe :)

Interesting, although I don't know why you bothered with the "Populated", instead of just leaving those spots blank like you did in some spots.

I may have to do something similar when I start stripping my Pole Position and Omega Race boards for acid cleanup....
 
Anyone who repairs boards with any frequency knows what all those chips are anyway :) -- now perhaps a reference to what page/region of the schematics that IC is on would be more useful -- the schematics show the function anyway.

That'd be far more useful for the boards where the IC part #s are commonly scratched off, like some Konamis.

A Konami custom chip chart would be something that would be VERY helpful...

A list of game boards with the information on which custom chips they use and which position on the board they are in... Along with what odd daughter boards can be used to replace specific custom chips.

Some had sockets with nothing in them, which I thought was strange. It is not really needed I guess
 
I agree with Mark, do this for the konami boards like Gyruss. Send me a blank copy of that form and I can make one up. Im pretty sure I have a Gyruss board that doesnt have the numbers scratched off so it will be a breeze.
I just looked at that page again...did you do that in html? It would be good to duplicate it in excel or something like that.

I thought it was Excel changed to pdf or something, then ported to the web...
 
Other information that would be nice would be for RAM and ROM have the addresses they cover by Chip Location.

For example, System 1 board will report a RAM error at $A00000 (or what ever it actually is)... would be nice to look at the chart and say "Ah, that's at 10A" ...

That's what schematics are for.

I THINK I went through on my Gyruss board and re-eched the names on them from the schematics. ... I know I did that to most of my Konami boards.

So, if you're just doing the customs list, I can probably help out a little.

FWIW: Cool project. I like stuff like this because you don't need it till you need it, then you REALLY need it. PITA hunting these things down sometimes.
 
The problem with referencing what address relates to what ram chip is that every board works differently...some may have each chip handle a certain address range, other boards like b&w ones use 1 bit chips so you can have say, a row of 8 that handle all addresses or multiple rows/chips for different segments, so it would really be address range AND bit(s), and make it substantially more work to assemble all this info. Not a bad idea, just a LOT of work when its really already shown on the schematic.
 
Then what's the point of this project? You can get all the information provided on the chart "From the Schematics".

Sometimes it's nicer to just have a handy reference without digging through the schematics...

It's always nicer for you when someone else does all the work for you, isn't it?
