/* ROMDOS formats */
[[Category:Expansion ROM]][[category:Disc Operating System]]ROMDOS was the most successful high-capacity disc operating system (DOS) published for the CPC. Originally developed by [http://www.tyndalearchive.com/Brewer/author.htm Dave Instone-Brewer] for [[KDS]], it was later resold by [[Siren Software]].
ROMDOS shipped on a single 16k ROM, though a RAM-resident version, RAMDOS, was also available. The ROM was essentially a modified version of the standard AMSDOS ROM, with support added for 80-track and double-sided formats. As a result, the format of the disc was detected automatically, just like standard AMSDOS - a big improvement over competing systems such as [[MS800]].

== ROMDOS XL ==
The file management utility suffered from severe limitations, such as a maximum 40k file size for copied files. In addition, the changes introduced some severe bugs to ROMDOS, initially including a loss of automatic format detection.
Though some of these bugs were later removed, ROMDOS XL never regained its place in the market, and [[ParaDOS]] became the most popular high-capacity DOS.Whereas in Germany the famous [[X-DDOS]] was the most popular DOS. == Manual ==* [[File:Ramdos.pdf|Manual]] == Adverts == * ACU Jan 1989 page 15. == Download == * [[media:RomDOS .zip|ROM DOS ROM]] * [[media:Rdosxl40.zip|ROM DOS XL 4.0 ROM]] * [[media:Rdosxl48.zip|ROM DOS XL 4.88 ROM]]
