Chuck,

Yeah, I've seen those adapters.  They are $5.00 each + shipping, plus 
require a bunch of soldering.  Not to mention, the SOJ chips aren't 
really cheap.  It could be $100-$200 job plus time for 8mb.

I've searched just about everywhere, including the amiga forums, and I 
just can't believe how un-popular these chips must have been.  The 256k 
x 4's in comparison are available everywhere.

I have some surface mount chips, maybe PSOPs, already that some kind 
soul mailed me for free a year or so ago.  I just found someone else 
with the knowledge to make these carrier boards (not hard if you know 
Eagle or the like) and we could likely get them cheaper if we buy a big 
pcb full of them.

I already considered making my own board, and if something falls 
through, that's likely what I'll do.  I would have to measure the 
surface mount chip because finding a datasheet for the chip has been 
particularly tough (and normally, I can find those types of things)  I'm 
sure it conforms to some standard so it would only be a matter of time 
before I figured out which it was.....

Obviously, and the reason for my post, is that if I could get the chips 
by themselves, it would likely save me time, trouble, and money.

Thanks

Keith
