[[category:Expansion ROM]][[category:Operating System]]The ultimate A [[DOS]] for 3.53½" drives, coded by [[Executioner|Richard Wilson]] and initially marketed by [[Quantum Computing]].
ParaDOS was a complete replacement for the standard 16k [[AMSDOS]] ROM. The first 8k was a patched version of the standard AMSDOS code, with the second 8k used for the large-format patch code and a user-friendly disc utility (accessed by the |DRIVE command without any parameters). Among the functions of the utility were fast file copying and batch erasing.

Among the functions of the utility were fast file copying and batch erasing. ParaDOS largely supplanted [[ROMDOS]] as the OS of choice among CPC usersAMSDOS replacement. Unlike ROMDOS, ParaDOS made no check for the presence of an AMSDOS ROM on sign-on. This enabled it to be used in ROM 7 as a direct replacement for AMSDOS, improving compatibility with programs which unthinkingly initialised ROM 7 alone. This, however, also cast some doubts on the propriety of its intellectual property stance. It is likely that ParaDOS would have been questioned more rigorously had it not been introduced towards the end of the CPC's commercial life. Unlike other expansion ROMs ParaDOS has no checksum in address &FFFF. This fact should be considered when performing f. e. a ROM integrity check or similar. It the usual checksum algorithm is used the checksum is &26. There is a special version of ParaDOS, it's called [[VaraDOS]] and has the Vortex format enabled by default. The Vortex format is the standard format for 80 track - doublesides drives, it was initially introduced by [[Vortex]] GmbH, then supported by all bigger producers of expansions and extensions for the CPC like [[Dobbertin]]. It's also supported in a variety of [[CP/M]] systems and [[FutureOS]]. == Systems Cartridges with Parados == * [[Media:English System + Parados.rar|English System + Parados.rar]]* [[Media:French System + Parados.rar|French System + Parados.rar]]* [[Media:Spanish System + Parados.rar|Spanish System + Parados.rar]] == Systems Cartridges with Varados == * [[Media:6128plus_English_VaraDOS.CPR|English System + Varados]] == Manual == * [[Media:parados.pdf|ParaDOS Manual in English]] (pdf)* [[Media:Manual_parados_espanol.pdf|ParaDOS Manual in Spanish]] (pdf)* [[Media:Pdos-ddb.txt|ParaDOS DDB and DPB documentation]] (txt) == Downloads == * [[Media:Parados_v1_0.rom|ParaDOS 1.0 ROM]] * [[Media:PARADOS_1-1.ROM|ParaDOS 1.1 ROM]] * [[Media:ParaDOS_1-2.ROM|ParaDOS 1.2 ROM]] * [[Media:ParaDOS_1-2+.ROM|ParaDOS 1.2+ ROM]] == Links == From the Winape web of Richard Wilson on the others downloads section you can download : - ParaDOS ROM - ParaDOS Source http://www.winape.net/downloads.jsp ==See also== * Review of ParaDOS in Amstrad Action (issue 99)[[image:ParaDOS_AA_review.jpg|thumb|200px|none]] * Second review (!) in Amstrad Action (last) issue 117{||-| [[image:Parados AA117 p17.jpg|none|thumb|200px|AA117_review]]| [[image:Parados AA117 p18.jpg|none|thumb|200px|AA117_review]] |} [[category:Disc Operating System]] [[category:Expansion ROM]] [[category:Manual]]
