Static RAM GS RAM Card



I'm new to this list. Please excuse me if this topic has been raised 
recently.

I have a ROM-01 GS with 512K of RAM. I've been looking for a larger RAM 
card because even if fully populated, my existing RAM card would be less 
than the 2MB recommended for System 6.

It seems to me that static RAM could be used to build midrange (2-4MB) 
RAM cards, certainly for less than some of the cards on eBay. Speeds for 
4MB (512K x 8) and 16M (2M x 8) are fast enough (and the GS clock slow 
enough) that one could use the DRAM control signals provided by the GS 
to latch the address lines and still have enough time to read and write. 

One downside is that these devices are only available in surface mount 
packages (which I *hate* to solder). OTOH, there are sockets available 
so I wouldn't melt the chip.

Any reaction?
