You're not very specific as to which C revision ROMSs you refer.  I assume
you're talking about the Rev. C BASIC.  I don't know if you can still buy the
Rev. C cartridge, but an easy solution would be to find a friend with a 130XE
(which has Rev. C BASIC), save to disk (from DOS 2.5 menu option K) the
BASIC cartridge ($A000-BFFF), then write an assembly language header to
precede the file you just wrote.  The assembly language header will have to
disable the BASIC ROM on your XL, then load the disk BASIC into the underlying
RAM, then reset RAMTOP to $A0, then clear the screen (by opening and
closing device #0).  Then, just do a JMP $A000 and your Rev. C BASIC from
the disk will run on your XL.
