Re: Q68 Notice 3 - Update

From a note on the other thread - it mentions 'fast ram area' What is that? Is this automatically available or are specific drivers required to harness it? The way I understand it there is an area where your code (or / and data accessed to if in this memory area ?) will run much faster. Very intere...

Re: Q68 Powered Arcade Game

Yes Peter, it is why I am very excited by your system, with its area of very fast RAM. For the incentive, to me, it will not be money because of the small users base, but most certainly contributions (coding, or 'simply' optimising some source code, graphics, original tunes and so on). Of course if ...

Re: Q68 Notice 3 - Update

Is anybody else but me interested in a highcolour arcade game for the Q68? Or is this totally unrealistic, after no QL arcade game was written in two decades? It sounds like Zarchos optimized routines could help. Could money be an incentive? Something like a mini-kickstarter where 10 people pledge ...

Re: Q68 Notice 3 - Update

Speed reduction: Considering you might want to plot sprites, there is a way to do that extremely fast, without masks, and most of the time with no loading of the 'background' to insert your sprite shape in it. The reason I want a Q68 is to adapt what I have completed writing for the Archie ('chunky...

Q68 Powered Arcade Game

Speed reduction: Note that, even if the contention created by video circuitry eats a lot of memory bandwidth, the 256 and 64k colour modes are way easier (and faster) to handle than the original QL modes: Setting a pixel in mode 4 or 8 means ⋅ pick the word containing the pixel from video...

I am going to be a pain in the a... but could the moderator delete not Q68 related posts, please (including mine). Thanks. Keeping threads readable should be evrybody's concern. We owe that to the fab work by the Q68 designer (to me). No offense, forgive me, I am a little bit to french (=very frank....

Re: Q68 Notice 3 - Update

In due course, would live to hear more about the spec of the expansion connector - one of the 'features' of the original QL that keeps me glued is the simplicity of designing add-ons using 8-bit, legacy speed components, prototyped on a breadboard or wire-wrapped. One day I might grow-up and enter ...

Re: Q68 Notice 3 - Update

Seems a little inconvenient if Derek ships them to me first and I must unpack/pack/post again. How about visiting the German Sinclair meeting next spring and let me sign them "live"? ;) Takes place on March 9-11 near Fulda. Hey hey ! Excellent proposal and a great opportunity to visit aga...
