It wouldn't be removed in normal use, and there was plenty of software
(not written in BASIC) that could be loaded without removing the ROM
PAC. However, anything in another PAC would require the removal of the
BASIC PAC, because there is only one slot.
Three items I know of came as replacement ROM PACs: the DEV PAC (Exidy's
assembler and editor - but there were others that just loaded from
disk/cassette), the WP PAC (word processor, but again there were others)
and firmware for one of the non-Exidy disk interfaces (most used only
the S100 expansion bus but one also used a PAC for its bootstrap rather
than putting that on the expansion bus).
There was also an EPROM PAC from a third party, so users could create
their own PACs.
