TECH: Namco Galaxians

[ukvac] TECH: Namco Galaxians
Does anybody know what's supposed to be in sockets 1.2R and 1.2S of a
Namco Galaxian? The sites aren't there on a Midway, so I've got no
documentation for reference.

Help!

Mike,

What locations do you mean, 1R and 1S or 2R and 2S?

Anyway
1R, 1S = 74S201 RAM (or many alternatives)
2R = LS08
2S = LS00

No, none of them

Namco boards, unlike all others I know about, have two extra sockets,
positioned at rows R and S, but _between_ columns 1 and 2, labelled
1.2R and 1.2S.

Great! Thanks.
I presume it is working with this configuration?

Yes I have seen it working like this.. but I have onyl just got the board.

What pinouts are you using for it ? As I would like to make a jamma
interface for it.. But dont have any pinouts for the NAMCO board.
Is it the same as the Galaxians pinouts listed on spies ?

[ukvac] Re: TECH: Namco Galaxians
Yes, the Namco board shares the same pinouts as the Midway. Then
there's that whole DC power conversion thing to worry about.
