Re: Reverse Engineering

Hi,
What about reverse engineering the QL itself ?

I seem to recall that the rights belonged to Alan Sugar Trading ?

And that QL Tinkering was allowed ... on the hardware.

But any other reverse engineeering is of course subject to such permission having been obtained.

Re: My next game on ACT - 1st problem random number within a range of.

Hi,
I have written some routines to emulate all superbasic's random functions.

But if ACT cannot acces superbasic, then no doubt you cannot use my routines either ?

Catch 22...

Steve.

Re: Beyond Super Gold Card

Hi Derek, Here is my new (rich text file) PASTEable version of the 'forgotten stipples' program, from WordPad. Do not LRUN it : LOAD it and type 'start' (to set up the channels), then RUN. Hit the 's' key to cycle through new hues ; OR 'q' key to cycle through QL stipples ; OR 'n' key to input any h...

Re: Beyond Super Gold Card

Hi Tobias, For the screen base, I tried CHAN_L(0,50) or SCR_BASE or SCR_BASE+$30, and variants, but still no success... except on my SGC (which has no colour monitor!). My QPC2 is set to 512,256 resolution, but as this is emulated, the mapping onto a high resolution screen must complicate BLOCK x &a...

Re: Beyond Super Gold Card

Hi Derek, Yes, I did try using the program using Simon Goodwin's Chans_code extension to get the screenbase address, but to no avail. (I am using QPC2). The 'new 'hues' might be useful for people with original QLs or GC or SGC . I still wonder how those machines were able to echo one stipple anywher...

Re: Beyond Super Gold Card

Hi Folks, I see that one of the main subjects of this thread is that the QL is limited to 8 colours, or 256 if you include stipples. But QL stipples only use two colours, combined in four patterns. Back in december 1993 Quanta printed a little program I wrote, using 'four-colour stipple' combination...

Re: Replacements for Zx8301 / Zx 8302 / IPC

Hi, After changing the keyboard membrane three times, I gave up, years ago. At a show, Tony Firshman fitted an external keyboard, passing its cable through the microdrive extension slot, (onto SuperHermes ?). No problems since ! Dilwyn supplied the keyboard. Everything still works fine : SGC, ROMdis...

Re: Travelling Salesman Program - Video

Hi Tomas, Optimal tour length is calculated using an LKH program. Shrink's percentages quoted are relative to that program. To get the outer polygon, first the southmost coordinate is found, then the outer nodes going clockwise. But, the C++ code uses 'convex hull' recursive routines.The outer polyg...
