Hey guys, I have a Ms Pac recently and it was in very bad shape.
It was sitting outside at this one place for about 6 to 8 months. So far, I put a cap kit into the monitor and got that working pretty well.
I am now working on the logic board. After hooking the logic board all up and to the monitor, I see jibberish on the screen. After removing some of the ROMs, I found the older ones at 6E, 6F, 6J and 6K (2532 type) all have at least 1 pin that fell off. I will have to replace these and probably the sockets for them as well.
Question 1: I am pretty sure I can use a 2732 as a replacement with a rewired socket or rewiring the traces on the logic board. Has anyone ever done this before?
Question 2: I am finding it hard to find a MAME site that has the ROM image for these chips. Does anyone have a link to a site that has them? The last one I went to wanted you to sign up for all kinds of surveys and junk just to download a copy.
Any help is greatly appreciated.
