I have what seems a earlier edition 2000 here, with a 4.1 rev MB. It had Kickstart 1.2 in it when I got it, but put in 1.3. Has 1MB Chip, not sure which Agnus is in it, I think Fat? Problem is I cannot get it to display a PAL screen in WB. When I invloke a PAL command screen goes black, if I type in NTSC it goes back to normal screen. But some games that load into PAL work fine? Its weird. Also I thought all 1MB Chip machines had the PAL capability?
