Here's a pic of of a prototype of a wonderful new peripheral for the QL: http://www.flickr.com/photos/petrip/5118906714/ And yes, it actually does something. This bad boy can display a byte decoded as BCD on its glorious two digit LED display: http://www.flickr.com/photos/petrip/5118293873/ Showing the result of poke 99072,66 :-D Nice! Learning electronics with the QL is loads of fun. There was a *lot* to learn for a software guy just to be able to do this one simple thing in hardware. Now that the hard part of interfacing with the QL is halfway there (no reads yet, just writes...) rest of the way to a fully working ethernet adapter should be easy ;-) Really looking forward to replacing pretty much all of the 74xx logic circuitry with a single Xilinx CPLD and starting to work towards hooking this baby to an Arduino microcontroller. Next week's agenda is building a JTAG adapter for the Xilinx chip so that I can program it. Whoops, need to learn Verilog first. Well, that's part of the fun :) If I had the time I would like to do such self-study experiments too. Keep on going! Cheers'Urs ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

The nearest I came to being able to fix this was to use the extra parameters of the WTV and WMON commands on QPC2 to move the basic windows out of the way instead: WTV ,32,256 WMON ,0,256 One day, I might search for '512' and '256' in the binary of QLib and see if these can be patched if they are really hard coded... :-( Dilwyn Jones ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

I got mine and a starter kit for about £50 all in. I always wanted a breadboard when I was younger and playing with electronics, couldn't ever afford one back then. The Arduino stuff is amazing, I really can't wait to start playing with those. I share Norman's history with breadboarding: always wanted to do it but first couldn't afford it and then didn't have the time. superHermes looked very like Petri's for a long time. Considering how critical and fast the main data link to the QL was, it was quite amazing it worked at all. It's actually very comforting to hear that comment about superHermes! So I'm not the only person fooling around with a jumble of jumper wires before committing to PCB:s. I also was concerned about the relatively high clock speed on the QL expansion bus when connected to the breadboard but quite a few people on various discussion forums seemed to agree that a breadboard should be able to handle approximately 10 MHz before the capacitive effects of the rails on the breadboard start to kick in. /Petri ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

There is one keyword for the Outline (necessary), built in QLib's inbuilt extension code, one to activate the pointer in a loop to detect, where the ponter is on screen for selecting the items. All loose items, their select/unselect colors and little borders are done under SuperBASIC. A clever little toolkit for small applications (if one knows how to use it). Other keywords (like REL_A6) seem to be used for generating the compiled code . Perhaps the SuperBASIC pointer loop detects, if 512x256 is reached, remind the time, where QLib was written. If it is done in SuperBASIC, it would be very difficulty to find these locations. If it is done in the MC procedure for activating the pointer, it is possiblemaybe.
