The Sinclair QL Forum

Nice, Dilwyn. INKEY$ need a channel, though, Better use a combination of SUSJB and KEYROW perhaps? Of course, if you close the channels. Only wrote that example to explain how to read absolute pointer positions from S*Basic without resorting to extensions. And your extension is perfect, much easier...

Not had time to try it out (I'm useless at games anyway), but looks absolutely superb.

To explain a little how it's done, and preserve this information for the future, as this is a potentially useful technique for those very rare cases where you need to read the absolute pointer position, here's a small demo of it written in BASIC. It only works on systems with pointer environment - I...

There is a manual for the CST RAM Plus card at https://dilwyn.qlforum.co.uk/docs/manua ... amplus.pdf (in case you didn't get one with it).

Thank you Per, saved me time writing an equivalent. Not tried it yet, looks a bit like what I would have done and straightforward enough.

The simplest might just be to open a tiny window, eg 0x0a0x0, and read the pointer with RDPT. If you really cant use an open channel for whatever reason there is my S\CRXY and GPT toolkit commands. SCRXY reads the size of the screen and GPT gets the current pointer position - both without the need ...

To save me reinventing the wheel, anyone know how (or if?) a program with no open CON channel can monitor the absolute pointer position on the screen? Happy to be told it's not possible or if I'm a fool to even think of trying it. It's for a little personal program which sits quietly in the backgrou...

Nice! Heard about those instore demo boards, but never seen a real live example. Thanks for the picture.

Never seen one of those before - what type is it (or is it homebrew) ? As you say, ties up the expansion slot. And depending on where in the memory map that puts the ROMs, might not allow expansions like Trump Card which use space allocated for ROMs to make up the difference between 640K total RAM a...

Yes, one of my QLs has a very old QLEA ROM switcher board where I can switch between a Sinclair and a Minerva internally. It even has different colour LED for both. The Minerva could do with updating at some point, it's not one of the more recent ones. The other QL has one of Marcel's QL-SD-ROM devi...
