The Sinclair QL Forum

Tobias, Thank you for explaining, I have also read pages 17+ from The Technical Guide, now with better understanding. I somehow realised, I also need to put an extra padding right at the assembly end. ... dc.w 0 end To ensure the binary has even byte size, is all in words so to speak. Otherwise job ...

Tobias, Rich, Thank you for padding suggestions, it now works, I use 100 as a delay in below line, as otherwise it playes really fast moveq #100,d2 ; Play it very fast I am getting binary and when loaded into reserved memory and then called from S*BASIC it works as expected and plays Bach's Prelude....

They also wrote a machine code routine to play music on the QL which was published in the October 1986 issue of Sinclair QL World - http://sinclairql.speccy.org/archivo/docs/mags/QLWorld_1986-10.pdf Hi, I have typed the assembly as printed in the mag, unfortunately it does not seem to work for me. ...

Line 2100 does not make much sense, I have all of the magazines, so will see if there is an errata. Otherwise, I will have to work out the logic of the statement Hi, I believe the line 2100 may read PRINT#tab," "(1 TO (mov_num<10));mov_num;".";TO 4;"ABCD"(side+1);"...

Derek,

I will try to improve the code further, I am just wondering if it would be also possible to somehow restore system variables after restart.

Dear All, I have hand coded the assembly, compiled and run the binary. Pressing <CTL> <ALT> <7>, resets the machine, goes to the initial screen, but does not clear the RAM, but does reset system variables. I cannot quite make out from the scan, these addresses, so I hope I got them right. WARM_RESTA...

Tobias,

Many thanks, I was not aware of "<CTRL><ALT>7" - key combination, I will certainly try. I am just curious, where this trick is documented.

Also, can I somehow achieve <CTRL><ALT>7 by a program?

Many thanks
Tom

Hi All, I have a plain QL setup that is, JS ROM, 8049 and TK2. I use SER2 to transfer data, SER1 as mouse port, and seldom SER1 to printer output. I sometimes experience problems with serial line, after exchanging data with PC, while reseting the BAUD will not help, and I need to reboot the machine ...

Rich, Derek, All,

I found this link for DEMO download, possibly only GERMAN version.

Rich,

I have found this archive reference to DI-REN, dates back to 1996-1997, not sure it is of any use.
