Tag Archives: SD card interface for QL

QL-SD Page

Now that QL-SD is available via SellMyRetro.com, albeit in small numbers so far, I’ve set up a page where you can download the manual, software starter pack and the BDI (Block Device Image) specification for emulators, thanks to Peter Graf for supplying the software and documents. I hope that as QL-SD becomes more widely available and used, this page can act as a source and repository for documents and files relating to the QL-SD

The page is at http://www.dilwyn.me.uk/qlsd/index.html

Also, thanks to Graeme Gregory, a version of qltools has been developed specifically for use with the HxC floppy disk emulator. This is available from http://www.dilwyn.me.uk/files/index.html

And while on the subject of QL-SD, most people choose to install one QL-SD, usually in the MDV2_ slot, leaving MDV1 free to work as a microdrive. For those who would like two QL-SD per QL (e.g. backup?), Paul Veltjens who builds these devices has confirmed it’s possible to install a second SDHC adaptor as device name SDC2_. Paul says he then needs to set a jumper differently and a cable with three connectors, one for your QLROMEXT and two for the two sd card interfaces.

Pictures below from Peter Scott:

The picture below shows the finished product – all you see is the SDHC card protruding from the MDV1_ slot of Peter’s albino QL.

No price set for this yet, so if you require such a setup, please ask Paul via QL Forum.
