[comp.sys.mac.hardware] mac+->SE

lwyse@thalamus.bu.edu (Wyse) (11/07/89)

I am thinking of upgrading a mac+ to an SE. If you have done such a 
thing, please be so kind as to tell me if all went smooth. WEre there
any unanticipated problems? What did it cost? How is the performance?

					thanks,

Er, upgrade a Mac Plus to a Mac SE?

The SE isn't all that different from a Mac Plus.  The SE has Apple Desktop
Bus ports (for the newer keyboards and mouse), an internal expansion slot,
a faster SCSI chip, slightly faster overall performance, and you can
purchase it from Apple with an internal hard drive.  That's about it.

Apple never offered a Plus to SE upgrade kit.  Perhaps you mean the Mac II
to Mac IIx upgrade.

I don't think it can be done.  You need to trade in your mac+ and buy
an SE.

Oh, I have a question - this is from SE -> SE/x (sorry, SE/30 :-)
Does it involve a board swap or do they just replace chips?
If you had a 3rd-party memory upgrade, can you still upgrade
to an SE/30?
Are they going to give you your old SIMMs back or will you end
up with 1 Megabyte?  The reason I asked is that if you had
a Mac128 3rd-party memory upgrade to 512K, Apple would
treat it as Mac128K (hence rip-off your chips)..

If they'll give me 1 Meg back for my 2.5 Meg 3rd-party upgrade,
can I "downgrade" my 2.5 Meg back to 1 Meg (put back the old
SIMMs and solder the resistor)??
