Hi,

I used SOX to convert WAV files to UB format that the SOUNDFILE commands will play.

I have some classical and rock songs converted plays on Q68 and Q60 at normal speed.

I am trying to write some keyword documentation for the Q68.

Can anyone tell me if the CACHE_ON, CACHE_OFF, and PROT_DATE commands have any effect in the Q68.

I suspect that they don't, but I just want to check.

Hi Martin,

I do not think they have any effect on the Q68, but I have email Wolfgang Lenerz for clarification.

The Q68 has no cache that could be handled by CACHE_ON and CACHE_OFF, and, to my knowledge, PROT_DATE is only implemented for the SuperGold Card (or was it the plain Gold Card?).

No they don't. I worked to implement cache on the Q68, but too much bad luck.
It is more likely to be implemented on the Qzero.

Hi,

I have just informed the the Q68 Ethernet driver was missing from the Q68 SD Card.

This can be downloaded from the QL Hompage:
https://dilwyn.theqlforum.com/internet/NETdriver114.zip
https://dilwyn.theqlforum.com/internet/N ... 14Docs.zip

I had only included the QoEdriver extenstions.

My apologies for the omission.

Thanks all for the feedback. I just wanted to be sure that I could mark these keywords as having no effect in the Q68.

Hi,

I have another question about the Q68 for the documentation I am trying to do.

I have been playing with the various display modes, and I have a question about the 16 bit modes.

I found some documentation about the 16 bit mode for the Q40/60

Code: Select all

MODE 33 (Q40/Q60) 16-bit colour

lowest address byte  highest address byte
7 6 5 4 3 2 1 0      7 6 5 4 3 2 1 0
G G G G G R R R      R R B B B B B I

The 'I' bit is an intensity control, common to red, green and blue. In
effect, it doubles the levl of colours otherwise available, since the
format allows 5-bit components in 15 of the 16 bits used per pixel.
The High and low address bytes seem to be the other way round in the Q68. But my main question is the 'I' intensity bit.

It does not seem to make any difference to me. But it might just be my eyesight.

Is that bit used in the Q68?

Hi Martin,

What documentation are you referring to?

The Mode 33 image files from the Q60, display okay on the the Q68.

In the SD Card sent with all Q68, in the directory PICART, there are zipped up PIC files I converted on the Q60.

This is the hardware manual, Q68 is compatible: http://www.q40.de/download/harddoc.pdf

It should make a difference. Probably easiest to see if you write 64 different grey levels.
