[comp.sys.atari.st] 520ST Memory Upgrades

FATR6@USU.BITNET.UUCP (02/26/87)

 
   Any ideas about what memory upgrade is best? I can't remeber the name
of the company but it says you can go up to 4 meg with the new 1 meg DRAMs.
Any comments? Has anyone tried this? (This is for a 520ST)
 
   Can you run both the DS/DD and SS/DD drives as A and B drives or B and A
drives?
 
Thanks

	I've been meaning to ask this for some while... can anyone out there
give me some info on upgrading a <<1 Meg>> 520 ST?  Specifically, if I want 2
Megs, would I have to rip out all those painstaking 250+ solder joints I got a
serious kink in the neck over?  And start again?  And somehow stay sane in the
process?  I know I've got an address somewhere in one of my usenet summary
files of a company offering a 2 Meg board (at least, I _think_ I've got that 
address...), and I want to know if anyone has looked into putting this into a
520 that's already been upgraded.
	Reply to me, and I'll summarize and post.  Thanks in advance.
