ResiDOS Downloads

The latest release of ResiDOS is v2.30.

For first-time installs, you can download the installer program for your interface in TZX or TAP format. Suitable software (such as playtzx or an emulator) for transferring this to tape for loading to your Spectrum is available from the World Of Spectrum website. (If you have a divIDE+ you may be able to copy the TAP or TZX file to a card/disk and load it from there using an existing firmware such as FATware.)

Once you have a version of ResiDOS installed, you can upgrade to later versions with one of these three options:

The BASIC loader program, which can be copied to your disk and used to upgrade to new versions of ResiDOS, is provided below:


ResiDOS for ZXATASP


ResiDOS for ZXCF (and ZXCF+)


ResiDOS for ZXCF+2 (and ZX-Matrix in CF mode)


ResiDOS for ZXUSB (ZX-Matrix in USB mode)


ResiDOS for divIDE Plus

Until a firmware selector is available for divIDE Plus, ResiDOS will not boot up automatically when you power on the Spectrum. To enter ResiDOS once your Spectrum has booted, enter the following commands exactly as shown:

    POKE 18455,237: POKE 18456, 65: POKE 18457, 199
    RANDOMIZE USR 18455

ResiDOS for MB02+ (and MB02+IDE)

This version requires a minimum of 256K SRAM onboard your interface. It also requires an MBIDE interface for hard disk/CF access (the MB02+IDE has this built in). It should also work if you have both an MB02+ (without MBIDE interface) and a divIDE connected to your Spectrum at the same time.

Note that you should not install the BS-DOS Ramdrive utility, as this will overwrite areas of the SRAM used by ResiDOS.

Until an updated bootrom is available for MB02+, ResiDOS will not boot up automatically when you power on the Spectrum. To enter ResiDOS once your Spectrum has booted (into BS-DOS or the standard ROM), enter the following commands exactly as shown:

    POKE 18711,237: POKE 18712, 65: POKE 18713, 199
    RANDOMIZE USR 18711

ResiDOS for ZX-Badaloc


ResiDOS for ZXMMC+


ResiDOS for divIDE (standard) with Velesoft's SRAM expansion
