How much to ask?

Your location?  
1st Amiga 2000:
Ram board (SLOW, useless to me) market value $10-18
Amiga board shows battery leakage already (worthless to me, i'm willing ot pay you for the chips in it though) you may get $30 for it
2 1571 Disk drives if they work $15-25 each.

2nd Set:
Amiga 2000 with 2091 $30-50 (I can't help but wonder if the batttery didn't corrode the motherboard either).
a yellowed C128 - $20.

and those values are pretty fair given the condition this stuff is in.  All my stuff looks 1000 times better, and i can post pics to prove it.

Well how much for yellowed C128 in your world?  Did you see Ebay?  $30-50 but you can't expect to get the same price on forums.  Anyway, at least I gave the poster some direction and tips, lets see you provide some prices? ;-)
