That is not necessarily the whole story. I have a 500 with 8372a Angus
but because I haven't changed the appropriate jumpers yet, my ami still
thinks its got 0.5 meg chip, 0.5 meg fast. (I suppose I had better get
around to changing, at least when I get more memory above the current
one meg - I've had my ami with 1meg for 2 years now! rev6a too).
To be sure which Agnus you have I recommend you either
 1. open up your 500 and have a look inside (you'll have to sooner
    or later to put 2.0roms in.
 2. use a program like Jon Potter's (at least I assume its his)
    SysInfo program (which was on megadisc 19 or 20 I think) and
    also should be around for ftping.
BTW which jumper do I change for 1meg chip - I cannot remember which
or where to look in my chaotic disk and magazine collection.

Also, and I've asked this before, is it true that you can put an 8372b
Agnus in a rev6a A500, with appropriate memory for 2Meg chip. Can some
one confirm or refute (and supply some backing evidence/more info)

Cya,
