I have a Jumbo tape drive running on Xenix 2.3.2 Using the 'standard" QIC-40
driver supplied with Xenix. It seens to work fine. I have never had a crash,
although I do get an error the first time the drive is accessed after a boot.
After that error everything works fine. I don't doubt that CMS's driver is buggy
but if you can use the one supplied with Xenix what is the incentive for them
to fix it?? :>)

It would be nice if they would supply enough info for us to write our
own drivers, but like everyone else who tried, I was told that they could not
supply any info. I really don't like dealing with a company that is so
uncooperative, I probably won't buy any more of their drives because of that.
It is worth paying extra to deal with a responsive company!!
Anybody know of a "responsive" tape drive manufacturer???
