The Sinclair QL Forum

I would try it in Q-emuLator with both Sinclair and Minerva, to see if is a Minerva issue in general, or specific to Q68.

Most games use the keyrow IPC QDOS trap. On Sinclair ROMs, the trap works fine when the rest of the OS is halted or disabled.

I would use an existing tool. Exiftool is pretty good and it works on most operating systems (except QDOS, until someone ports Perl to it). As an example of usage, here is a command from a Windows script I wrote in 2010 that copies images from the camera to folders based on date: exiftool -r -d E:\F...

Interesting idea, I wonder how it sounds, given the low quality of the QL internal speaker.

Does T1 still mainly use the original tracks and components layout, or was it entirely redone?

Never mind, I eventually found the info here: http://www.qlforum.co.uk/viewtopic.php?t=3048

The service manual shows the connections here:
I guess Sinclair left it as implicit that the other end of the cable has the same pinout.

Forget what you labeled the "mDrive bus": That's the PCB connector on the side of the QL, for external microdrive units, and it has a different pinout. In your case, my understanding is that you'd like to connect the MDV replacement's connector to the connector on the QL motherboard. From ...

Nice project! Glad to see you are still QL-active!

I'm assuming the kb row required is input via a rd of x18003 and the 8 bits are returned via x18021 - but I may have this wrong. The keyboard is connected to the 8049 and the ZX8302 only provides a serial link to it. Unless you change the ROM to use a different communication method, you would have ...
