Update - 8 June 2008

A new version (v1.03) of the TapeIO package is now available. This contains a couple of bugfixes (see the what's new page for details). Additionally, the %TAPELIST command is now enhanced and provides details such as data array names, BASIC autorun line numbers and CODE start/length.

Also, I have added the following programs to the additional software page. These have been patched to work with ResiDOS:


Update - 10 May 2008

A new version (v1.02) of the TapeIO package is now available. This contains a bugfix; files ending at address 65535 were considered to potentially overwrite the ROM, and loaded in slow mode. These files now correctly load in fast mode.


Update - 6 May 2008

ResiDOS v2.07 is now available! This contains a number of bugfixes. There is also an updated version of the TapeIO package, with a bugfix. For full details of the changes, see the what's new page.


Update - 6 April 2008

A version of ResiDOS is now available for users of the MB02+ and MB02+IDE interfaces (with more than 128K of SRAM)! This can co-exist peacefully with BS-DOS, provided that you do not install the BS-DOS RAMdisk driver, which will overwrite SRAM used by ResiDOS.

Additionally, an updated version of ResiDOS for ZXMatrix interfaces (in ZXUSB mode) is available; now at v2.06, this provides various fixes over the preliminary version that has been hosted here.


Update - 16 March 2008

ResiDOS v2.05 is now available!

As well as a raft of bug-fixes, there are a couple of major improvements: firstly, ResiDOS will now detect a single drive whether it is configured as a slave or master (previously only master drives could be detected singly); and secondly, upgrade files are now available to copy direct to your card/disk, so tape installation is only required if there is no version of ResiDOS installed on your interface already.

Support has also been added for the new second drive option of the ZXCF+ and ZXCF+2 interfaces, as well as an optimised version for the ZXCF+2 and a new version (still in development) for the ZXUSB interface on the new ZX-Matrix interface. Full details of these interfaces may be found on Sami Vehmaa's Homepage.

Full details of all changes can be found on the What's New page.

Additionally, the IDESpeed benchmark has been completely revamped, and now includes 4 speed tests. It now also runs on ResiDOS; previously it was only available for the +3e.


Introduction

ResiDOS is an extension to ZX Spectrum BASIC that operates with various add-on interfaces providing extra memory and hard disk or compactflash/SD card interfaces.

ResiDOS installs itself into your interface's onboard RAM together with a modified copy of the Spectrum ROM, and then provides you with extra BASIC commands for accessing files on the hard disk or compactflash card, and using the extra RAM on your interface. It also provides a comprehensive task manager which can be reached using the NMI button and allows you to instantly switch between a number of programs or games running on your Spectrum.
