Talk:Sinclair QL

message: Although the computer was rather advanced for its time..the japshung..
Was it, really? I seem to recall that in fact its major failing was that it was nowhere near as advanced for its time as it should have been. Contemporary of the Mac, which really was a "quantum leap" in computing for the masses - sphincter at a price. The QL was stuck with a very old fashioned operating system design, old fashioned mass storage (as the 3.5" floppy age was about to dawn), and certainly nothing like a GUI. It had "windows" of a sort but they tiled up the screen into, at most, 4 sections. They didn't overlap. Each ran one DOS-like shell or session. The term QL was little more than hype (or maybe wishful thinking). Sure, it may have been a quantum leap from the Spectrum, but in absolute terms, very much an also-ran. The only thing it 
did get right was its CPU choice, which was very good for its day.Graham 
:Maybe. At the time I worked for a computer company where, aside from the minicomputers we were programming, we had a Mac and a QL: the Mac was the toy we drew pictures on when we had long compiles going, whereas the QL was seen as a huge step up from the 8-bit Micros of that era. I think the Mac was significantly more expensive too. Mark Grant 15:57, 12 July 2006 (UTC)
replies: text: Even though the QL was quite different than many other computers of the time (although, compared to the first Mac, the QL had a color output on both monitors and TV screens), and did have its shortcomings, it was certainly an extremely expandable computer.  My father's QL, by the time he stopped adding things to it, bore very little resemblance to the QL he bought in the mid-1980s.  Microdrives were horrible little things to use, so he eventually added four disk drives: two 5¼" and two 3½" - the first time I had actually ever used the latter.  The compatibility with the Atari 2600 joysticks was genious.  Virtually any kind of printer available at the time could be used with the QL, too.  Processor power could be greatly enhanced with the Gold Card, Super Gold Card, etc.  My father even installed a patch to allow a regular PC keyboard to be used instead of the somewhat awkward QL keyboard, though this did require some technical know-how, as well as a drill to put a hole through the QL case.  So, with a little bit of patience and a bit of elbow grease, one really could turn the QL into a real powerhouse of a computer. --Ericdn (talk) 06:44, 6 March 2009 (UTC)
thread_title: Although the computer

message: Since 1984. we are talking about is still a huge 8-bit computing era, Sinclair QL
was a quantum leap from them, and to not yeat existing Amiga and Atari. 
 -  QDOS has a concept of OS, compared to Commodore or Sinclair ZX series. This is
    nice OS, even multitasking compared to MS-DOS of the time. It even includes
    the best BASIC (SuperBASIC) ever built in ROM of home computer and is
    also a last computer with it. This both bonus. Compared to later GUI of
    Commodore 64, Amiga Workbench, early MacOS and early Windows QDOS sucks,
    but with further expansions, even after Sinclair went broke, similar
    GUI/mouse concept was introduced for QL and sucessors.
 -  Microdrive is a fair solution. It offers a 100K storage for 128K computer.
    C-64 and PPC floppies of the time were 180K Single desnity. And you
    get two of them enabling easy backing up, copying etc.
    Latter, and interfrace for floppies and hard drives was introduced.
-   It was not only good CPU but first home computer with good keyboard, 2 mass
    storage devices included, hi res graphic and bussines package bundled.
    Also you had a 10 microdrive package included, so it shipped with blank media too.
 In short, it was a good balance, a computer bridging home and personal computer era,
 but tried to be sold to early,with bad company behind it that cound`t even ship
 the orders. 
- Choice of CPU: As I recall, the 68008 chip was 16-bit internally (& thus a leap forward from 8-bit chips). Unlike the 68000, though, the cheaper 68008 used an 8-bit data bus thus bottlenecking the chip. Sinclair chose the 68008 for budget reasons, but did not therefore gain the full benefits of 16-bit technology. Two steps forward & one step back doesn't make a quantum leap.
 Yes, yes, but never forget that famous 68 000 CPUs that run Amigas 500/600/2000, Macintosh,
Atari ST ... had everything same, just could adress more memory. And they didn`t use
over 512K as standard for several years. So at the time this was smart budget decision,
much better than a Intel of that time.
- Use of Non-Standard Budget Hardware: Low pricing was part of Sinclair's business strategy. This meant keeping costs down & one way that was done was by using cheap hardware. E.g. the membrane keyboards on the ZX80 & ZX81 & the infamous "dead flesh" keys on the Spectrum; the small thermal printer which burned output onto rolls of silver toilet paper; and of course the microdrives, which used a thin loop of video tape in a small, hard casing as the storage medium. Was this better than cassettes? Yes. Was this as good as floppy discs? No. Microdrives didn't have the storage capacity of the 5.25" 360Kb floppies, let alone the new 720Kb ones. At least the QL had a pretty decent keyboard.
    I agree with Spectrum expiriences but QL was different story - hardware and software
costed about 3 times as similar ones for Spectrum and you could get good printers,
floppy drives, expansion cards offering a lot of power. Floppies were about 360K
standard of that time, but floppy drive unit costed about half price of QL. So
again, for this price better microdrive than tape system of C-64 or Spectrum.
* Not to mention that the microdrive was far more robust, faster and actually more reliable than 5.25" floppies. Lars T. 16:49, 24 November 2005 (UTC)

...deliveries only started, slowly, in April.
So, what was the date wheb QL was told to be seld ? What to compare April with ?
This was something that Sinclair always did.  They would start taking orders months and months before they had any hope of ever having a single unit ready to ship.  I bought a ZX Spectrum in May 1982, and was told it would be delivered in 28 days.  After about 6 or 7 weeks I received a letter from them saying it would now take 6 months!  I told Sinclair Research that I wanted my money back, and finally, in September I got a refund, but only because I turned up at their Camberley office and said I wouldn't leave until they gave me the refund.  They eventually did, after I had stood there from 10.30am until 6.30 pm.
They were always a bunch of amateurs and their computers were a pile of cack.    —Preceding unsigned comment added by 81.178.228.93 (talk) 21:19, 15 October 2007 (UTC)

thread_title:  Bingo 

message: "Plagued by a number of problems from release, particularly bugs in the QDOS operating system and SuperBASIC which led to multiple releases of the firmware."
Can the author identify any "bugs in the QDOS operating system" [Comment added by TT - see Talk for Sinclair QDOS ]
"Multiple releases of the firmware". 
After the launch of the QL the "software development team" moved out of Sinclair Research's main building into a building site owned by the company to try to decide what sort of system software the QL should have, based on the expectations raised by the launch. The result was the first test version for sending to an evaluation panel: FB (named after Francis Burdett? the Sinclair driver who drove me back from my meeting with Sir Clive at which I resigned). Versions PM, AH, JM followed at about weekly intervals. These test versions included early versions of a rapidly evolving SuperBASIC. There was also a side test version TB that was after JM, but I do not know whether this was seen outside Sinclair. 
3 bugs were found in the operating system in test version AH. The next test version JM had what was the final test version of QDOS (final, because no bugs were or ever have, as far as I am aware, been found in this version of QDOS) this was also sent to testers bundled with SuperBASIC in ROM (the microdrives still did not work reliably enough to ship software on). This version of SuperBASIC differed from the AH version in that the parameter order for one of the graphics commands was changed and there were some minor fixes.
As testing failed to uncover any more problems in JM there were no more test versions and it became the first release version.
So you can ignore all the rubbish that has been written about it: JM was actually released before any QLs, flaky or or not, were shipped. I had already given my notice - the day the first QL was shipped I walked out of the door, never to return. The rest is chaff. Sinclair shipped flaky QLs with ancient development versions of the operating system, graphics and SuperBASIC in a dongle hanging out the back either because 1) (the "official internal" version) buggy software was more acceptable to the press than faulty hardware 2) those who had developed the software had left the company in disgust over the premature launch - slandering them seemed a good way out a deep hole. "Les absents ont toujours tort" - always blame those who are not there.

thread_title:  Facts please 

message: Has anyone ever seen one of Linus Torvalds alleged QL programs, the Assembler and the game Cool Man (Pac Man clone)? Or are these things just legendary pieces of code that might exist on his own old floppies somewhere? Nixdorf (talk) 12:38, 1 March 2009 (UTC)
thread_title: Dig up Torvalds programs

message: This was tagged for tidying up in Jan 2009 (per WP:TRIVIA) and AFAICT has remained that way since. I'm now removing it, and here's a link to the section before doing so. Text copied below, refs retained in previous version of article (not copied here, so as not to clutter the talk page).
* Linus Torvalds, creator of the Linux kernel, owned a Sinclair QL in his youth and used it to learn programming.
* The QL's Intel 8049 Intelligent Peripheral Controller actually ran at a higher clock speed than the 68008 CPU (11 versus 7.5 MHz).
* When connected to a normally-adjusted TV or monitor, the QL's video output would overscan horizontally. This was reputed to have been due to the timing constants in the ZX8301 chip being optimised for the flat-screen CRT display originally intended for the QL.
* QLs built by Samsung for export markets had DE-9 sockets for the RS-232 and joystick ports, instead of the unusual and UK-specific BT630W (similar to BS 6312) sockets found on UK-built QLs.
* External QL Microdrives appeared on QL accessory pricelists but were never produced. However, ZX Microdrives could be connected to the external Microdrive interface and performed flawlessly on a QL (actually offering higher reliability than the built-in ones).
