(which also limits the usable RAM).  See:

http://www.vintagemacworld.com/lc_card_faq.html

"Macs which have an LC-compatible PDS slot AND which support 24-bit memory
addressing can use the card. System 7.0 through to System 7.5.5 support
both 24- and 32-bit addressing on suitable Macintosh models; from System
7.6 onwards, Macintosh system software does not support 24-bit addressing.
To enable 24-bit addressing, use the Macintosh Memory control panel."
