[comp.sys.atari.st.tech] Mega2->Mega4 Upgrade?

svrobins@npe.isnet.inmos.co.uk (12/04/90)

Can anyone tell me what I need to upgrade my Mega2 to 4 Megs?. Can I do
this by simply plugging/soldering the extra Ram, or do I need to do 
anything else eg cut/insert links etc. 
 
 If anyone has done this job (without an upgrade kit) I'd appreciate 
any info.

Thanks,

Paul Robins.

	Apparently some Mega 2s were made w/o space on the mother board
	for a extra 2 megs (most were) If you have the holes just add sockets 
	and (and 3 resitors, probably 68 ohm[some already have the resistors \
	)) 


	Otherwise you need a clever soldering iron or a 3rd party board.

	On an unrelated note, I'd like everone to send me the plans on how to
	hook up a IBM mouse to an atari.  I have a PS/2 mouse, however any detailed plans on how to hook up 
	either the bus or serial mouse to an Atari would be very apprciated


	  Thanks 
       a bus or serial mouse to an ST would be greatly apprciated.
