Logicworks is available for the Amiga, sort of.  If you look in older
issues of _Amiga_World_ you will see ads by Capilano Computing, makers
of Logicworks.  I ordered this software about 10 months ago.  A few months
after I ordered, I received ``version 0.9'' at no cost.  This is a preliminary
version, lacking some very important features such as the ability to create
device libraries, print your schematic, cut and paste type editing, etc.
Capilano sent this out at no charge to all who had ordered as a show of good
faith, claiming that they had run into some problems, but they were working on
them.

This preliminary version is great, though.  It allows the user to enter a
logic design as a schematic.  It knows about the basic parts, such as
flip-flops, muxes, AND gates, OR gates, etc.  Also has some simple I/O in
the form of probes, hex display, etc.  Also, it will simulate the entered
circuit, producing a timing display in the lower window.  It uses the
standard Intuition type of Amiga menu selection that we've all grown to love.
I am a "soft-head" who has had to become more hardware literate (for my
employer) in the past year, and I have found Logicworks to be very useful
as an educational tool.  Unfortunately, in its present form, lacking the
ability to define more complex devices, it is not really useful for real
design work.

By last December, I had been using KS/WB 1.2 as my default boot-em-up
on the Amiga, and I had discovered that Logicworks 0.9 did not work well
under 1.2.  Further, my hardware `wa' had grown, and I wanted the ability to
create more complex circuits.  I had heard absolute nothing from Capilano
in the intervening six or seven months.  They still had not charged my credit
card for Logicworks, either.  I wrote them a letter asking about a ``real''
version, with device libraries, printing ability, 1.2 support, etc.  I also
told them that I thought their program was fantastic.  The bad news is the
reply I received, quoted below:

            /* yes, this is a "Dear John" letter  :-)  */

Dear John:

Thanks for your letter regarding our LogicWorks package for the Amiga.  We
appreciate your encouragement and support, but unfortunately there haven't
been enough others like you to make it economically feasible to continue
development of the Amiga version. Just so we're not leaving people in the
lurch, we will be releasing a version which works correctly under 1.2 within
the next couple of weeks.  We will notify you at that time and you can
purchase that version for $99.95.  Beyond that, we will not be doing any
further development unless something dramatic happens in the Amiga
Market to change our minds.

                                   Sincerely,
                                   Chris Dewhust

This is a sad commentary!  Shades of Turbo-Pascal!  I want to emphasize that
this was not a completely vapor product.  Capilano has been very honest with
me, providing me with a pre-release version at no charge.  I did not ask for
this, they just sent it out to everybody who had ordered.

Maybe a rush of interest in (and orders for) the Amiga version would
change their minds.  As for me, I won't be sending in my $99.95 for a
crippled version of the program that happens to run on 1.2.  I still
have my 1.1 kickstart, and on those rare occasions that I want to run
a crippled version of LogicWorks, I will boot my Amiga with 1.1.

Sorry this is so long, but it's a subject I've wanted to bring up in this
forum for a while now, and the question posed by Flynn seemed like a good
opening.
