The Sinclair QL Forum

Hello Stephen,

I did not know that Xenix was foreseen to become MS-DOS. However if they could not make a "simple" system like MS-DOS compatible with an "advanced" system like Xenix, certainly based on all the best theories about system software, then:

- either they had utterly bad programmers at ...

Excuses I do not come every day.

From 1976 to 1995 only single tasking microcomputers were accepted by the public simply because multitasking systems based on academic research were not usable with the then available microprocessors. Except the QL with a completely different system software. Indeed ...

OK a few words about this analogy. The semaphore/mutex/lock concept is associated with waiting lists of threads/processes when another one already "took" the permission to access the shared data structures to read or possibly modify them.

This is like traffic lights protecting a crossroad. The ...

Hello @SinclairSociety

I had the same question back in the beginning of the 90's, 25 years ago. I contacted Tony Tebby who just moved to France. And he explained to me during months, because I am not a computer scientist, why QDOS/SMSQ is different, maybe better.

Hello Vitaly,

The Super Gold Card was sent only today (20 February). Expensive! So I hope that you will receive it in a few days...

OK, so I will leave the heatsink as is (it would also have made a smaller parcel). About the memory of SGC, I understand that the max is 4MB. To receive back a clone of Super Gold Card that works exactly like the one I will send to you is enough for me to be "paid". And do not bother about the time ...

Hello Tetroid (Vitaliy),

So Dave does not need a SGC, my mistake because of a message about a file with equations above. And Marcel informed us on his blog that he can wait for your clone to test his new developments.

So this Super Gold Card is for you.

About price: what about sending me one of ...

Hello from France,

I have an unused Super Gold Card that I would send to either Tetroid to the far east, or Dave to the far west, or to Marcel, Germany.

It is one of the first produced, I got it from the hands of Stuart Honeyball himself during a show, maybe in 1993 (I have not found the invoice ...
