I bought a USED 1000 a couple of months ago and have been having great
fun with it.  The previous owner put in a 68010 and did some upgrade
that came from the net or an Amazing Computing article.  Here's what
it did:

	- moved 256K of Kickstart Ram into useable ram 
	  (there's a call to a program called "addmem ..." in startup-seq)
	
	- he burned his own PROMs (KS 1.2) 
	  and put them where the KickRam went.

I took the box apart recently and saw that I have a Rev A motherboard.
The daughterboard had a few changes made to it.

HERE'S MY QUESTION:  is anyone familiar with this modification and
how does it affect my chances for expansion.  I'm thinking of adding
some more RAM, maybe a HD.  What about putting in 1.3 ROMs (or 1.4). 
Could these go where the PROMs are now?

Thanks in advance for any information.  I realize that most of the 
discussion on this topic probably occurred 3 years ago and I'm a
little behind the times with my little A1000.
