of the 1541 Ultimate.
Key changes:
MircoSD instead of SD cards
no optional Ethernet until further
notice

1541 Ultimate II announcement
Dear 1541 Ultimate enthusiasts,
Some of you might have noticed that
the order form has been temporarily
closed, and many questions and
rumors' have been going around about
the future of the 1541 Ultimate. The
reason behind all this, is that
behind the screens I have been
working on a successor of the "1541
Ultimate". How this unit will be
called has not yet been determined,
but it could be something as simple
as "1541 Ultimate II" or "Ultimate
Cartridge".
What is it, and why was it designed?
Basically, it is a scaled down
version of the 1541U. It will provide
similar functionality, although some
things have been changed. It will no
longer support full-size SD-cards,
but only MircoSD, or "Transflash".
Also, Ethernet will not be supported
until further notice. It will support
tape emulation out of the box
(without the need for special FPGA
images) and it will provide a
real-time clock function with battery
back up. Audio output has been
significantly improved, which might
seem useless for just the drive
sounds, but this enables the creation
of FPGA images that provide
additional sound channels of useful
quality. The power consumption has
been reduced as well. There is one
extra cool feature that will not yet
be disclosed ;-)
And last but not least...
This unit will come with a case! At
least, that is the plan; there are
some negotiations going on with
manufacturers for plastic insertion
mounding. It seems feasible to have
this done, although it's pricy for
low quantities. A prototype is
3D-printed this week; the prototype
board is already there and functional
Now, speaking of the case....
Since I like to keep the high
compatibility with the 1541, the big
DIN connector is still there on the
board. It might be an option to use a
custom connector for this, with a
custom cable that needs to be made
for this unit, but to be honest; this
does not have my personal preference.
I would need to have these made
separately, and stock them separately
as well. So, let's say that the big
DIN connector is a fact, how do we
enclose this? There are two options;
which are shown below:
And the second option is:
As you can see, the first one has a
"strange" bulge, but is for the rest
rather elegant, while the second one
is symmetrical, but bulkier. Which of
the two it should be, I don't know..
Maybe I'll open a poll for this, what
do you think?
Availability: It will still take
around 12 weeks before these units
can be delivered; which means late
October 2009. Price: I tried to keep
the price acceptable. Due to the
case, it has to go up just slightly
though. The selling price including
tax is ? 125; (excluding: ? 105).
Please let me know what you think.
Regards,
Gideon
Open sourced!!
The software part of the 1541
Ultimate is from now on Open Source!
Although the hardware still needs to
be documented, people can already
check out the source code, edit it
and build new applications for the
1541 Ultimate! The source is released
under GPL 3.0, which in short means
that every addition to the source
code will also need to be open
sourced and the code or parts thereof
may not be sold. The full license
agreement can be found in the 'root'
(trunk) of the SVN archive.
In order to build the software, you
need to do the following:
Install Cygwin, or run under Linux.
Make sure you have:
GNU make in order to run the
makefiles.
GCC compiler, in order to build the
conversion tools.
Install CC65 (http://www.cc65.org),
and make sure you have the required
environment variables and path set.
Install a SVN client package (either
command line in Cygwin) or a
graphical client such as Tortoise SVN
Check out the repository from
http://svn.xp-dev.com/svn/gideonz_
1541Ultimate/
Go to the trunk directory and type
'make'.
At this point, the archive is
read-only. If you are a developer and
want to make a significant
contribution to the 1541 Ultimate,
please contact me and we can discuss
being a write-user on the archive.
Bug fixes from others can be E-mailed
as patches, which I'd happily merge
with the archive.
Happy programming!
