Re: Some speed tests on QL hardware

Hi All,

Just got a result from a friend with an AMD, w10, 1.46Ghz, Qemulator :
fast mode gets 16551 loops, 128k mode gets 141. ( speed factor of x117 ! )


What speed does a real 128k QL achieve ? (In order to define speed factor = 1...)

Regards,
Steve.

Re: Some speed tests on QL hardware

Hi All,

In the retabbing by Bwinkel67, read ' +/-% ' column. Many thanks for the retabbing.

Steve.

Re: ZXSimulator

Hi again,

Unfortunately, the tabbing in the timing figures got removed by the site ..... Spaces between colons were removed !

Perhaps the site administrators could look into this ?

Best wishes,

Steve.

Re: ZXSimulator

Hi Bwinkel67, You have mentioned that assignments are slow. I have timed the main SMSQ/E operators, which all return roughly similar speed timings, (including coercions). Printing with AT or CURSOR barely slow timings, and BORDER width has little effect. But assigning x=y then x=y+y*y-y/y only slows...

Re: Beyond Super Gold Card

Hi per, The program now appears to be correct with all QL and QPC2 MODE combinations. Graphics ouput is OK with QPC2v3.31, but one pixel wrong with QPC2v4.02 !

Re: Beyond Super Gold Card

Hi per, Yes, I have done a fix for this problem, in as much as I now get 256 colours. But that still leaves a problem wuth QL stipples : If I tweak for these, the mode 4 then mode 8 screens are often offset by 1 pixel ! I will report back as soon as I understand the reason for this..... Many thanks,...

Re: Beyond Super Gold Card

Hi All, The QL to QPC2 screen transfer program is now finished, (in so much as are my requirements). Modes 4 and 8 are catered for. There is no point in using SCR_XLIM or SCR_YLIM etc, as they return the size of the full QPC screen, irrespective of the actual size used. I manipulate binary string$ i...

Re: ZXSimulator

Hi Bwinkel67, There is another trick to print smaller charcters fast : 1 : Using standard font characteristics : 2 : Define your font characters, placing your pixels in the top left-hand corner. 3 : Print, using CURSOR for justification. (Beware of margins). 4 : The rom drivers then print at normal ...
