Q630 extra ram slot soldering.
I've just read http://www.lowendmac.com/quadra/630ram.shtml which describes how a 630 can get an extra ram slot by soldering on a 72-pin ram slot into the empty pads on the motherboard. However, that doesn't fit with my 630, that extra slot which is just solder pads doesn't have enough pins! the other slot has all 72 pins. Is this article mistaken, or are there other kinds of boards? Either way what would this slot be for? ta dana -- -- Quadlist is sponsored by http://lowendmac.com/ and...

A lot of early Macs had either a removeable ROM or a soldered on ROM with an additional ROM slot in case Apple made an update to the firmware for the machine.

The one you have, and another one with solder pads for a second 72-pin ram slot. The smaller slot (with 64 pins) might be for a ROM simm. I have examples of both on hand. I don't know if either works, as they came in other piles of parts (I think I bought one for the 68040 with FPU). Anyway, the point is, there are indeed at least two versions of the board. The one with the extra SIMM socket has a few other minor differences in component placement and such as well. Jeff Walther -- Quadlist is sponsored by http://lowendmac.com/ and...
