But, on a 464 with ROMs enabled and config 3 (c3 etc) is chosen we see:
&0000-&3fff: base ram &0000-&3fff &4000-&7fff: upper rom &8000-&bfff: base ram &8000-&cfff &c000-&ffff: upper rom

== Software ==
Dobbertin supplied [[RDOS]] as a optional ROM to use the memory expansion as RAM disc with 444 KB free. They also supplied CP/M 2.2 and Plus with full support of the RAM disc. Other software using this RAM expansion: [[Discology]], Xexor, [[Cosmos]], [[On File]], [[Punishment]], [[Disc'o'Magic]], [[Pyradev]], Alyssa Database, [[CPC Word]], [[FutureOS]] and [[ParaDOS]]. Arnor software like Prowort ([[Protext]]) and Maxam [[MAXAM]] II also support the usage of the RAM disc.
