Ardie,
The so called "FATTER AGNUS" will give you allow all of 1 MEG of
memory on your A2000 motherboard (or the 512K motherboard and the 512K
expansion memory of an A500) to be used as CHIP RAM. So you will still
have a total of 1 MEG.
I think all you do is change the chip, and maybe reconfigure a jumper
or two. I be able to tell you for sure tomorrow, as I have one being
delivered then and will be installing it.
Just because it does not add any memory though, don't be fooled into
thinking it is not an important upgrade. Many people I have talked to say
it is one of the least expensive ($100.00 or so) and most important
upgrades you can make. A 512K Chip Ram Amiga that is multitasking might
have 512K available memory, but possibly most of the Chip Ram full. I have
had system crashes that I think are because operating close to full on the
Chip ram side, even though I had 200K of memory available.
I let you know more after I install it at do some experimenting.
Mike
