Replace the IWM (Integrated Woz Machine) chip with a SWIM (Super Woz Integrated Machine) chip and replace the original ROM chips with the ones containing updated firmware for the SWIM chip. Good luck finding either. ROM and SWIM upgrades were also made for the Mac II to add 1.44M floppy drive support and also to correct a bug which limited the size of SIMMs usable in Bank A. I don't know if the SWIM chip for the SE and Mac II are the same. The ROMs are not. -- ----- You received this message because you are a member of the Vintage Macs group.
