Re: What makes the OS for QL any better, different, unique ?

From this perspective, QL was much compromised design, can be viewed as simple, higher level of integration led to just a few IC chips used. H/W and system extensible, compact and nice industrial look. Yes, PCs had better keyboard, but mind the price. Interesting about QL paths, encoded in the file ...

Re: What makes the OS for QL any better, different, unique ?

Well, "a single file" is how the Finder presented it but it was two parts True, but still two files, compared to various settings, tweakings, paths, directories, prefixes, suffixes, registrars, uuids, security files, etc, etc. I know, is an imprint of evolutionary development, old legacy ...

Re: What makes the OS for QL any better, different, unique ?

Hi Ben, Yes, you are right, it works as long as you still pass the event loop. It was an unfortunate example, need to correct my statement, I tried to compare sort of break functionality across systems ~ `Ctrl-C'. EDIT and probably the app has to be programmed that way, please see the programmer's r...

Re: What makes the OS for QL any better, different, unique ?

Not sure it was mentioned here, on cooperative systems, you cannot write loops while (true) ; This locks entire system, on preemptive you can, however is sometimes difficult to find badly formed loop end conditions. On Apple Mac, you pressed Apple [shredder] Key plus dot [,], to escape from locked a...

Re: What makes the OS for QL any better, different, unique ?

Finder/Multifinder wouldn't let you (may have something to do with wanting to protect the resource fork...dunno why else they made that decision) The resource fork contained executable `CODE' blocks 16/32K each, plus a jump table blocks, acting as page file, no virtual memory needed! That's what I ...

Re: What makes the OS for QL any better, different, unique ?

Hi, Reading first document `25 years have gone by since the launch of the QL' The ill-fated XENIX system should give an idea of the slowness of Unix. When this was launched (just after the QL) on an IBM PC XT platform (about 4 times fasler than a QL with 10 times as much working memory) Not sure I g...

Re: ST Basic - inspired by QDOS?

Yes, indeed. Remember my 1st ST 520 machine, had just owner's manual + quick basic manual, listing keywords only.
There was no Logo manual either, these had to be bought from ATARI corp. separately.

Re: ST Basic - inspired by QDOS?

Hi, Just paying a visit after a while. ST BASIC was not a bad prog in my opinion, it introduced a novelty of windowing, 4 distinct windows, list, edit, output and command. Was not of the fastests, that is for sure, but featured builtin debugger, with trace capability! It did not catch on, lack of pr...

Re: Custom QL Retrobrighting

Hi,

Cool. Just wondering what is that brighting formula, something women use to dye their hair, that is peroxyde based paste? Unfortunately my missus uses mahagon colours. Not useful for my ATARI ST machine.

Re: John Conway: Game Over

Hi, Nice prog in commemoration of Conway. Over the summer I did some reading on `Surreal Numbers' (only half understood), a new maths apparently also founded by Conway. The theory further leads to `Strategy Games', with interesting property, that for some games a winning strategy exists in the domai...
