but surely the code can be fed into the samc compiler no - sam vision erm it looks close?! are you sure that as teh filled in cube rotates it wouldnt be easier to drop to mode1 couldnt you fill 64 pixels of colour witha single byte attribute square only need to work out how many you could get away with seems a bit jerk how many frames does it take to draw? have you tried the echologia demo with the dma and mb-02+ in real spectrum - not sure if they are using the dma tah much some models take 3 to 7 frames to draw wouldnt a sam dma be a wee bit faster than the quoted 17jb per frame velesoft reckon the dma datagear interface handles in on128k also do you need masterdos to detect an external sam - its only another 3mhz but what about those register hungry emulators like the apple and oric or whatever its called oreo - isnt that a biscuit? did you catcht eh text font.... its taken me a loooong time silver paint tonight pressure sensitive keyboard membrane here i come! - didnt realise the 128keypad had a pic controller in it dont they go up to 80mhz! theres development kits in maplin £44 or build it your self for £25ish grade b=£20 http://www.maplin.co.uk/Search.aspx?menuno=12483
