In a BASIC Extensionion you should also be able to safely use the BASIC buffer.

The most annoying thing IMHO is that uEmacs warps the pointer to some unexpected place if you select a menu item. I keep searching my mouse pointer in that program. Isn't it similar in QD? When you click on an item with the mouse from the editing window, you first have to look back at where you ...

I would of liked more integration with the Extended Environment, but QD does all that, I use both to write programmes.

I think the big thing to sort out is the mechanism for loading and executing code that either stops the OS task scheduler and disables interrupts, or both? Also, I'm not clear, though I am sure many here are, if it is possible to return to the operating system after this step or if a restart is ...

Even today, most of the vi commands have left their traces in muscle memory.


I’m using QED on the QL and I still keep trying to use vi keystrokes even though I haven’t really used it since the early 00’s


I used to have a colleague whose text files sporadically had an arbitrary "ZZ" at the ...

Its amazing how dependent we have become from comms infrastructure.

On the topic:
"Back then", I never understood why someone would want to cope with ...

Dave,

no, "owning" the machine (disabling multi-tasking and interrupts) is really a piece of cake - some machine code instructions and it's yours. "Coming back" from that state is similarly simple.


; go to supervisor mode and switch off the scheduler

I favour a utility to do flash programming.

The timing loops can be avoided by using a facility that most flash vendors provide - which is a 'busy' bit that can be read - if it's still set, you loop around until it's cleared - then move onto the next bit/byte/block and so on.


That's called ...

Writing a Flash update program isn't really rocket science - you write some magic byte sequences to some magic addresses with proper timing. Writing a generic flash updater, however, is. You not only need to detect the exact ID of the part (that information can be queried from the chip), you also ...

Today I received ... the keys to our new house in Dyke, a small village near Forres up here in NE Scotland. It's taken three years but we've finally found a house! The bad news is, the mobile phone reception there is worse than it is here, so our hope of mobile broadband working better than here ...
