If anyone needs specifics, let me know by email. Tell me where you bought your 1M Agnus. (You should try asking them for instructions first). Adam NOTICE ------ If your Amiga is still under Commodore warranty, you may void that warranty by handling chip replacement yourself. Please keep that in mind, and consider having an authorized Commodore Amiga Service Center perform this replacement. -- Adam Keith Levin -- CATS Commodore-Amiga Technical Support 1200 Wilson Drive / West Chester, PA 19380 (215) 431-9180 BIX: aklevin UUCP: ...{amiga|rutgers|uunet}!cbmvax!adam
