Hmm. I wonder if most people are familiar with 7Zip? I have to use Windows at work, and this is the "zipper/unzipper" of choice. It's free and better than just about anything I've had to use in the past.

Right-click a zip file and "open with 7Zip" or "extract here" and it's done.

The web site is at https://www.7-zip.org/ and from there the list of files covered is:

* High compression ratio in 7z format with LZMA and LZMA2 compression.

* Supported formats:
Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.

* For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
* Strong AES-256 encryption in 7z and ZIP formats

That should be enough for everyone! Of course, we have to convince "most people" to get their finger out and do something for themselves! :) :)


Cheers,
Norm.

The reason for not implementing this down-able SD Card image was there was little adverse opinion on users not having the knowledge to create SD Card images and how to write boot files. So I did not do it.

I would go for ZIP format, because this needs no 3rd party software to be installed on any OS.

I would not fear the skills of people to write an Image to an SD card, just propose them Win32DiskImager. Anyone using Linux normally has the skills to do such tasks anyhow. :D

Hi,

I will consider this, what Q68 SD Card images would be required?

Hi,

A backup SD Card image is now available at:

https://www.qlforum.co.uk/downloads/q68/Q68-2019-12-30.zip

This a compressed 4Gb SD Card image, which includes:

SMSQ/E v3.34
QL/E v3.19
Black Phoenix v1.5
Q-Dock
Qpac2
Sample boot files
Documentation on FAT drive

The image file should be unzipped and use WIN32IMAGER to write to a 4Gb SD Card.

The image creates:
FAT32 partition with QWA container files, SMSQ/E QWA file
FAT partition with Q68, QL/E documentation, SD CARD Format software.

Replacement SD Cards are available priced:£10 plus postage

I can produce any specific type of SD Card for the Q68.


Regards,

Derek
