Did anyone hear about QNX which was the product of QUANTUM
SOFTWARE SYSTEMS?
They (QSS) sent us the price list as follows:
QNX $650 Multi-User, Multi-Tasking, Real-Time O.S.
C $300
QDOC $300 Text Formatter
QDOS $60 DOS Emulator
QMAIL $150 mail system
QMENU $150 Menu Package
QSPELL $199 Real-Time Spelling Checker
TED $50 Terminal Editor
We orderd a demo disk. It seems to me that their system is very fast. However,
I don't know if it is ?NIX-like O.S. They also sent benchmark results
as follows:
OS Computer Processor Measusre(msec) Normalized(msec)
------------------------------------------------------------------------
QNX IBM-PC 4.7MHz(8088) 1.35 1.4
UNIX ONYX 4MHz(z8000) 6.56 12.3
XENIX ALTOS 5MHz(8086) 10.4 14.1
UNIX CODIA 8MHz(68000) 5.34 15.2
XENIX Intel-286 5MHz(80286) 4.93 20.7
UNIX FORTUNE 6MHz(68000) 10.5 22.4
Question: Does anyone have the experience on QNX?
What is your opinion about it?
Is this QNX another ?NIX-like? If it is not, how
much difference is there between System V/4.2 BSD and QNX?
Have you ever tried to run QNX multitask or multiuser?
(QNX says that it can support 17 users. Is it true?)
I will summarize all the information and post it. Thanks in advance.
