For Windows95, DOS and LINUX (release 0.90)

Last update of this page: 19990130. QLAY and QLAYW release, with executables and source code.

QLAY, what is it?

Design idea of QLAY is to fully support the Sinclair QL hardware. All original I/O is emulated. There is no focus on adding emulation for hardware extensions like floppy or hard drives, video cards etc. One exception is made: Native File Access allows access to the DOS/Linux file system. With these hardware components emulated, all original QL/QDOS software can be executed on QLAY. Newer QDOS versions are thus supported as long as they run fine on the original QL hardware.

QLAYT tools 0.90 is the support program for QLAY. (56k)

Access DOS files in QLAY as WIN1_, and many other features (19990130).

QLAYT provides a set of tools and general support functions for the QL emulator QLAY. The tools are needed because the QL and it's operating system QDOS have some pecularities that do not match well with most other Operating Systems. Most obvious difference is that QDOS files consist of two parts: a header block and the actual data file. To allow transparent access from the emulator program to the native file system it's needed that the file header is stored separately.

The QLAYT program takes care of inserting or extracting files into/from a directory file. It knows about datasize fields. And will import and export files from other QDOS compatible systems and QLAY's MDV file format.
