Welcome.

Let's explore the world of esxDOS software for ZX Spectrum 48KB and 128KB/+2A/+3 computers (and compatibles, incl. ZX-UNO) with DivIDE, DivMMC, DivSD storage interfaces or the MB03+ Ultimate interface.

Download: 36.2 MBytes 7zip archive (updated 2021-02-14)

Every piece of software is split into normal single zx-files with (or without) +3DOS FAT headers. You can copy and move these files both on your Linux, Windows or Apple computers as well as on the original ZX Spectrum and use same SD/CF cards between them.

The good news is that emulation files and old-storage legacy files, like TAPs or TRD images, are not needed at all. Thanks to the esxDOS, new software supports LOAD/SAVE files directly from/to SD and CF cards.

Copy the whole content, all directories and included files, to a FAT32 formatted CF, SD or MicroSD card.
NOTE: Do not copy SYS and BIN folders, if you are using another version of the esxDOS system.

Speed test (esxDOS v0.8.7): Try the HQ Digital Audio Player Demo by LMN128 in the MB03PLUS/LMNHQDAP folder. It takes only 1:27 minutes to load 15 megabytes of data into the MB03+ in the DivMMC mode. A direct access to files stored on FAT formatted SD cards is super-fast.

ZXDIR ROM

helps you work more comfortably in ZX BASIC and esxDOS, using these enhancements:

• DIR (renamed CAT) at the place of the COPY keyword
• tilda sign at the place of the pound sign
• abbreviated keywords (RAND, CONT, GOTO, SCR$ etc.)
• cursor movements in EDIT zone up and down
• INPUT, LET, PRINT, OUT, IN hexadecimal numbers, up to &FFFF
• several small bugs in original ROM repaired

It is a slightly patched version of the ZX Spectrum ROM and all its improvements are very small and hardly interfere with the old ZX ROM code at all, thus guarantee (unlike most modified sophisticated ROMs) a high compatibility with ZX Spectrum software.

ZXDIR ROM does not contain modified BASIC commands. Nowadays new cmds can be performed otherwise, by the esxDOS "DOT-commands" stored in the BIN system folder.

esxDOS-compatible patched ZX ROMs

• ZXDIR3.ROM with DIR, tilda, edit. cursor and hexadec. input
• ZXDIR2.ROM with DIR, tilda and edit. cursor
• ZXDIR1.ROM with DIR and tilda only

• "Pretty" ROM, modified by E. Likov
• GAMA81 ROM, modified by M. Pikula
• 64Char ROM, modified by Busy
• GOSH Wonderful ROM, modified by G. Wearmouth
• GROOT ROM, modified by H. de Groot
• IMC ROM, modified by I. Collier
• Derby PRO, a 64KB +3ROM by A. Owen
