Hi Kevin,

 > How fast do you plan for the timer to go (interrupt)?

Well if you'll read the articles I've posted, you'd see that we plan on it only
'popping' once as a single-shot.  We'd disable the (F)IRQ flags inside the
interrupt routine immediately.  The 12-bit number will need to be changed/reset
for each/next period needed by the application(s).

 > Have you written any code yet? - kev

I've not written any 'useful' code for the timer yet.  Eddie Kuns on Delphi
responded with F$SSWI probably being the fastest AND most flexible way of doing
things, of the three I mentioned in that last text file.  I'm also not going to
update my MFConv/MFPlay package until we get some support for the timer
completely wrapped up and some standards set, again as I mentioned.

Mike Knudsen brought up some of the questions I had in the text file.  I'm very
sure several people are waiting for some of these ideas to congeal so we can
get on with this project.

I'm kinda worried, still, about a sentence in your "Inside OS9" book I got from
FHL quite some time back.  Page 7-1-6, fifth paragraph:  "Storing a $00 at
$FF94 seems to stop the timer."  But Page 7-1-2 says "FF94 Timer MSB .. Write
here to start timer", and Tandy's Service Manual concurs on page 12. Confusing.
And I suppose I store the LSB before the MSB?  (how wierd; can't do a simple
16-bit STore, then, huh?)

I'm very pessemistic when it comes to our Community trying to work together on
such things:  Shoot, we lost our only User Group; and Tandy has ditched us; and
we're having to wait sometimes weeks and months for replies on what we need to
have and where to go next.  Not to mention 99% of the readers couldn't care
less about what we're trying to do!  On the networks I can access, that is.

And I can't access the networks I need to ask these questions on.  Most
importantly whether any other machines/systems have such timer support as I
asked in my original text file several months ago.
